- Description: This study is a part of an environmental research project aimed at providing assessment information to the grain-size distribution, mineral compositions, sedimentary structures and coastal erosion and rehabilitation methods along the Swartkops estuary, a recent developing industry area of South Africa. The methodologies used in this study comprise desk study of literature, field geological investigation and sampling, and laboratory analyses including grainsize analysis, thin section microscope study, XRD mineral composition study and SEM-EDX grain surface texture and composition analyses.The basement and surrounding areas of the Swartkops estuary consist of three formations: the Enon Formation of mainly conglomerate, the Kirkwood Formation of sandstone and mudstone, and the Sundays River Formation of dominantly mudstone with sandstone, which integrated as Uitenhage Group of Cretaceous sequence with modern estuarine sand and alluvial sediments filled in the entire basin. Grain size analysis is a useful tool to assess hydrodynamic environments. The grain size parameters showed that most of the Swartkops estuary sediments are moderately sorted with very few well and poorly sorted, coarse to fine skewed in grain size distribution.Whereas the Bluewater Bay beach sediments are mostly fine grained, well sorted, fine to coarse skewed in grain size distribution. The bivariate scatter plots are an indication of shallow marine environment by beach and coastal processes with the influence of water flow and wind influence during transportation and deposition processes. Mineralogy studies revealed that the Swartkops estuary sediments are dominantly composed of minerals such as: quartz, calcite, feldspar (orthoclase and plagioclase), aragonite, clay minerals (smectite and illite), and salts such as NaCl and MgCl2. Skeletal carbonate minerals (shell fragments) are more than chemical precipitated carbonate minerals. Quartz is the most abundant detrital mineral observed in all the sediments and it comes from inland and transported into the estuary and the beach by fluvial streams, whereas skeletal calcite/aragonite is the most abundant biogenic carbonate derived from sea side and transported by marine currents. The study shows that grain surface textures reveal the existence of several features that reflect the depositional environments. Observed grain surface textures by microscope and SEM include V-shape pits, upturned pits caused by mechanical crashing and corrosion during transportation; crystalline precipitation of calcite, quartz, salt and clay by chemical precipitation and crystallization; dissolution pits and pores formed by dissolution, and burrow and boring by biogenetic activities. The grain surface morphologies are closely linked to different formation mechanisms and depositional environments. Well-developed sedimentary structures have been found in the beach and estuary, including sand dune, sand ridge, straight and sinuous ripple, ripple marks, aeolian nail marks, high angle tabular cross bedding, antidune, rill mark, rhomboid mark, swash line, mud crack, gravel pavement, interfering ripples, flat topped ripple mark, linguiod mark, asymmetric sinuous ripples, dendritic pattern on sandy beach, boring and bioturbation, burrows desiccation cracks and water escape hole. Different sedimentary structures are reflective of different hydrodynamic conditions and depositional environments. Coastal erosion is a major problem for damage of road, bridge and properties in the industrial areas in Swartkops, which is also a task for this study. The author had suggested some practical mitigation-methods to local government, such as groins, revetments, shoreline hardening, planting of vegetation, and vertical walls, bulkheads, sills, which could be useful for the protection of coastal erosion. , Thesis (MSc) -- Faculty of Science and Agriculture, 2021

- Description: Pre-harvest technology of shade net is environmental friendly and was found previously to improve fruit growth and yield. In addition, it reduces wind blemishes and sunburn, and effectively act as a buffer against climate fluctuations, such as excessive light, wind and hail damages. However, commercial shade nets are capital intensive; therefore, it is important for farmers to understand its impact on fruit quality that is desired for export market and assess whether the investment is profitable to the industry or not. It was brought to attention that several citrus cultivars grown in Addo, Eastern Cape under 20percent commercial shade net shows sensitivity to chilling injury (CI); however. no information is yet documented about the impact of this technology on fruit quality. To determine the efficacy of 20percent-shade net technology in relation to the control (no shade net), the present study was designed with the objective to compare internal and external quality parameters of ‘Washington and Cambria’ navels, ‘Valley Gold’ mandarin, and ‘Eureka’ lemon fruit grown in shade netted orchards and stored at low temperatures (4 and -0.6°C) for 30 days in Addo area, Eastern Cape. Internal quality attributes assessed includes juice content, °Brixpercent, titratable acid (TA), °Brix:acid ratio and average number of seeds. External quality data assessed include rind colour, and fruit size, firmness/texture and fresh weight loss. For chilling injury, fruits were evaluated by examining the degree of rind pitting and assigning levels of severity namely 0, 1, 2 or 3 where 0 = no pitting detected, 1 = 1 pit, 2 = 2 or more pitting detected and 3 = severe pitting detected. The post-harvest experiments were done on fruits harvested from commercial citrus orchards in Sundays River Valley, between Kirkwood and Addo (33° 34' 0" South, 25° 41' 0" East), in the Eastern Cape Province of South Africa, over two harvesting seasons (2018 and 2019). The ‘Eureka’ lemon and ‘Washington navel’ fruit were collected from Allendale farm; the ‘Cambria’ navel fruits from the Nuwelande and Olifantsbos farms; and the ‘Valley Gold’ mandarin fruits from the Dunbrody/Unifruitti farm. The quality attributes were recorded in the Laboratory of the Citrus Research International (CRI), Port Elizabeth, Eastern Cape, South Africa during Season 1, and in the Horticulture lab of the University of Fort Hare (UFH), Alice, Eastern Cape, South, Africa during Season 2. The experimental layout was a typical pseudo randomised completely block design (RCBD) (not truly randomised) whereby treatments tested were subjected over time (pre-test, post-test). The two treatments i.e. shade vs. control (no shade net) could not be randomly allocated to orchards due to the practical issue of working on a commercial farm, . The sub-factor consisted of three postharvest treatments: Ambiemt temperature (at 0 days storage), 4°C and -0.6°C storages for 30 days. Secondly, an experiment to evaluate the impact of petroleum-based wax mixed with 2-(4-thiazolyl) benzimidazole [thiabendazole (TBZ)] (TBZ: 500 mg.L-1) on shade net vs control fruits was conducted. The fruits were stored at 4°C and - 0.6°C (coated) for 30 days and were evaluated after 7 days storage at room temperature. Shade net did not significantly affect the internal quality attributes of citrus fruits. The 20percent- shade net promoted size of ‘Washington’, ‘Cambria’ navels and ‘Valley Gold’ mandarin, whilst rind colour was not affect. Firmness loss was higher on ‘Eureka’ lemon and ‘Washington’ navel, regardless of the growing conditions and cold storage duration. Rind firmness of ‘Cambria’ navel and ‘Valley Gold’ mandarin were not significantly affected by shade net and storage duration. ‘Eureka’ lemon was found to be more sensitive to CI. However, the application of wax+ TBZ eliminated CI on all 4-cultivars. Therefore, it is recommended to apply wax+ TBZ in packline to eliminate CI and fungal development. , Thesis (MSc) -- Faculty of Science and Agriculture, 2021

- Description: This study sought to explore the experiences of foster care youth who had exited the system within a period of three years in Makhanda Town, Eastern Cape. The coping mechanisms employed by foster care youth after exiting the system, and the policies, legislations and support services available were explored. The study adopted a qualitative research method. Non-probability sampling was employed to recruit 23 foster care youth who had exited the system within three years in Makhanda Town. In addition, 6 professionals dealing with statutory cases, three (3) foster parents and one (1) key informant were selected. Data was collected through the use of face-to-face semistructured individual interviews with foster care youth who had exited the system. The focus group discussion was held with professionals dealing with statutory cases and the ward councillor. The researcher analysed the data thematically. The study findings revealed that long term and comprehensive planning was important so as to provide a consistent and all round support to the fostered youth during the pre and post foster care phases. It was established that for most foster care children, the lack of a complete plan affects their transition from their biological home through the foster care system. Consequently, they come out more vulnerable than when there were initially placed in foster care. The study highlighted the serious need for training and job placement for the youths, a structure that is currently non-existent. The study recommended that the Department of Social Development (DSD) should make it compulsory for statutory social workers within the foster care domain to come up with individualized and personalized plans that outline the needs and deliverables for each child placed in the foster care system. Importantly, DSD must create a framework that is endorsed and accepted by all stakeholders so as to achieve the best interest of the child in all situations. Furthermore, the study recommends that DSD should employ more social workers to address the current human resources shortages in foster care units. Lastly, the study recommends restructuring of placement system to be less paper-work for effective and efficient, integrity, and quality of the service provision. , Thesis (MSW) -- Faculty of Social Sciences and Humanities, 2021

- Description: Invasive alien plants (IAPs) are introduced species that constitute a self-sustaining population, consistently producing offspring in large numbers and at considerable distances from the parent plants with the potential to spread over a large area. Species invasions are one of the main conservation threats today and have caused modification of ecosystems, particularly in coastal areas. Therefore, Port St Johns Local Municipality (PSJ LM) was an appropriate study site to evaluate the local awareness and perceptions of IAPs. The study investigated the local community’s perceptions of invasive alien plants' uses and ecological impacts. Information about the local awareness and perceptions of invasive alien plant species in PSJ LM was gathered through semi-structured interviews, observation and guided field walks with 120 participants between February and April 2021. The participants included 30 people working on the alien plant eradication project in PSJ LM (Wards 1, 2 and 3) and 90 randomly selected community members. The data collected were entered in Microsoft Excel 2016 programme and analyzed for descriptive statistical patterns using Statistical Package for Social Studies (SPSS) version 22.0. Biological invasion by IAPs was ubiquitously perceived, with participants working on invasive alien plant eradication project in the area exhibiting more scientifically based knowledge on IAPs than ordinary community members. Invasive alien plants in the area appear to have adverse environmental and socio-economic impacts, as the participants are not benefiting from these plant species. Similarly, costs of eradicating these species were also acknowledged. The ability of local community members to identify IAPs is vital in effective management of the spread of these species. A total of seven invasive IAPs were recorded. Evaluating the perceptions of local people towards IAPs provides valuable insights for development planning and future management programmes focusing on biological invasions. The study will provide a basis for an enabling policy and institutional environment that provides a coherent framework for the sustainable management of IAPs in the Eastern Cape Province. , Thesis (MPhil) -- Faculty of Science and Agriculture, 2021

- Description: The benefits of participating in sport have been well documented and great emphasis has been placed on the role that it plays in the development of character and social skills, apart from physical and psychological benefits. Sport represents an optimal means of enabling children and adolescents to meet their daily requirements for physical activity to maintain health. Conversely, despite all of the widely acknowledged benefits, participation in sport among children and adolescents continues to decline throughout the world. Although a great deal of research has been conducted to identify barriers to participation in sport, most of it has concerned poor, rural, disadvantaged, or other marginalised groups. As a consequence, a large proportion of the research has attributed low rates of participation in sport to practical barriers, which usually take the forms of either logistical problems or a lack of resources. The aim of this study was to identify the barriers to participation in sport among adolescents in an affluent, urban setting, at an international school in Cape Town, South Africa. The Barriers to Sport Participation Questionnaire was used to identify the social, personal, and practical barriers that affected 107 adolescents who were enrolled in the school. The data was analysed by means of the SPSS (IBM, Version 27) software package and seven significant barriers were identified. Fear of academic failure, environmental constraints, and lack of interest were identified as the primary barriers, thereby emphasising the significant influence of personal barriers, rather than practical ones. It was also found that the influence of particular barriers was greater on females than their male counterparts and that the respondents who either did not participate in sport themselves or were from households in which other members did not do so were more adversely affected by some barriers than the others. Significant correlations were found between some grades and certain barriers, the most notable being those between respondents in Grades 7, 9, and 10 and the fear of academic failure barrier. In light of these findings, it could be concluded that the global decline in participation in sport among the youth is a complex problem and that particular barriers, which might not have been identified in previous research, could be particularly influential in affluent environments. As it is evident that as barriers can be specific to particular groups and settings, the optimal means of overcoming them is unlikely to be found through the adoption of a one-size-fitsall approach. Instead, further research and customised interventions are required. , Thesis (HMS) -- Faculty of Health Sciences, 2021

- Description: The exposure of livestock to antimicrobials for treatment, prophylaxis, or development advancement can select for antimicrobial resistant organisms that can be transmitted to humans. Salmonella as a significant zoonotic microorganism can go about as a likely supply of antimicrobial resistant determinants. Salmonella is a zoonotic pathogen that causes food and waterborne infections. It affects wild and domestic animals, and humans, by causing a number of infections including Salmonellosis. Salmonella species infect humans through the consumption of contaminated meat, like beef, chicken, pork etc. This study aimed to determine the molecular characterization and antimicrobial resistance profile of Salmonella species isolated from effluent discharged from the Fort Hare Dairy Farm in Raymond Mhlaba Local Municipality. Polymerase chain reaction (PCR) was used for the molecular confirmation of the presumptive Salmonella isolates targeting both ompC gene and typh gene. Standard disc diffusion method was used for the antimicrobial susceptibility testing (AST) as recommended by the Clinical and Laboratory Standards Institute. The confirmed Salmonella isolates were tested against 12 test antimicrobial agents and were screened for antimicrobial resistance genes (ARGs) including blaTEM and amp for beta-lactams, and tetC for tetracycline. The research showed that the effluent discharge from this farm is contaminated with Salmonella. Presumptive Salmonella densities were ranging between 1,7 ×102 to 6,1×102 CFU/100ml, out of 83 presumptive isolates recovered, 61 were molecularly confirmed Salmonella typhimurium. The most prevalent Salmonella species found in this study was Salmonella typhimurium, which was more abundant in the final effluent discharges than in the water samples. This may be due to the contamination from farm animal faeces. The susceptibility against 12 different antibiotics by the recovered Salmonella typhimurium were examined, and Salmonella typhimurium isolates was notably resistant to azithromycin, ampicillin, amoxiclav, but less resistance were seen on doripenem , meropenem and ciprofloxacin but none of the isolates were resistant to norfloxacin. Antibiotic results obtained from this research suggest that Quinolones (Norfloxicin, Ciprofloxacin and Nalidixic acid), and Carbapenems (Meropenem and Doripenem.) were the most effective antibiotics against Salmonella. Forty-eight percent of isolates were found to be resistant to more than 3 antibiotics from different families thus considering them to be multidrug resistant. Resistant determinants ampC, blaTEM and tetC were detected on resistant isolates. Misuse and overuse of antibiotics on animal producing farms put human lives at risk as it promotes the emergency of multidrug resistant bacteria. Findings of this study revealed that animal producing farm pose a threat to the community as they harbour and promote the emergence of multidrug resistant Salmonella typhimurium. , Thesis (MSc) -- Faculty of Science and Agriculture, 2021

- Description: The exposure of livestock to antimicrobials for treatment, prophylaxis, or development advancement can select for antimicrobial resistant organisms that can be transmitted to humans. Salmonella as a significant zoonotic microorganism can go about as a likely supply of antimicrobial resistant determinants. Salmonella is a zoonotic pathogen that causes food and waterborne infections. It affects wild and domestic animals, and humans, by causing a number of infections including Salmonellosis. Salmonella species infect humans through the consumption of contaminated meat, like beef, chicken, pork etc. This study aimed to determine the molecular characterization and antimicrobial resistance profile of Salmonella species isolated from effluent discharged from the Fort Hare Dairy Farm in Raymond Mhlaba Local Municipality. Polymerase chain reaction (PCR) was used for the molecular confirmation of the presumptive Salmonella isolates targeting both ompC gene and typh gene. Standard disc diffusion method was used for the antimicrobial susceptibility testing (AST) as recommended by the Clinical and Laboratory Standards Institute. The confirmed Salmonella isolates were tested against 12 test antimicrobial agents and were screened for antimicrobial resistance genes (ARGs) including blaTEM and amp for beta-lactams, and tetC for tetracycline. The research showed that the effluent discharge from this farm is contaminated with Salmonella. Presumptive Salmonella densities were ranging between 1,7 ×102 to 6,1×102 CFU/100ml, out of 83 presumptive isolates recovered, 61 were molecularly confirmed Salmonella typhimurium. The most prevalent Salmonella species found in this study was Salmonella typhimurium, which was more abundant in the final effluent discharges than in the water samples. This may be due to the contamination from farm animal faeces. The susceptibility against 12 different antibiotics by the recovered Salmonella typhimurium were examined, and Salmonella typhimurium isolates was notably resistant to azithromycin, ampicillin, amoxiclav, but less resistance were seen on doripenem , meropenem and ciprofloxacin but none of the isolates were resistant to norfloxacin.

- Description: This study examined water struggles and rural people’s experiences of waiting in South Africa’s Eastern Cape Province. Primarily, it investigated how such struggles connect to people’s experiences of waiting for water services. In essence, the study demonstrates how experiences of waiting are profoundly shaped by subjective meanings that the rural people attach to water at a local level. Thus, the study connects rural water politics to contested meanings over natural resources in South Africa’s communal areas. The empirical analysis in this study goes beyond the largely urban focus in the focus in the politics of waiting – mainly in the informal settlements, slums and other urban peripheries. The study presents some of the less known struggles of rural dwellers, particularly their experiences of waiting for water service provision from the state. South Africa’s Constitution promotes the right to clean water. Despite all the progress made by the democratic government, it is still evident that people in deep rural areas of South Africa are in a very precarious situation when it comes to accessing clean water. The study utilised Auyero (2011) concept of the politics of waiting to examine the poor people’s experiences of waiting for water. The study adopted a case study of Lower Didimana village. The researcher conducted a range of qualitative research techniques – the key informant interviews, focus group discussions, observations and semi-structured interviews. The study found that rural residents of South Africa continue to wait for long periods for water service provision in the current democratic era. Moreover, they are still faced with severe challenges of accessing water; as a result, they are left with no better option but to use traditional ways of retrieving water. It also found that there are strong cultural and spiritual claims that rural dwellers attach to water. To them water is not just only a physiological need which could be addressed through efficient state service – the provision of sufficient tap water. Water is deeply connected in human existence. Just like land, water is a cultural as well as spiritual resource. As such, rural experiences of waiting are not limited to state agency and how the poor experience the state, but are also influences by local struggles over meanings of water. Finally, the study reveals the limitation in state policy on water provision, which is locked in a purely engineering use based paradigm, which mainly strives to address (technically) scarcity of drinking water. However, the findings of this study demonstrates that drinking is just one function of water. Although villagers try to mobilise to engage the state while waiting for water service they articulate other claims that connect to diverse water meanings. Such meanings are barely captured in contemporary literature on rural politics of water. As such, although water is increasing becoming scarce in rural South Africa and the state intervention is increasingly demanded, villagers’ experiences of waiting in Lower Didimana remain strongly connected to what water means to locals. , Thesis (MSoc Sci) (Rural Development) -- University of Fort Hare, 2021

- Description: Small to Medium sized Enterprises (SMEs) play an essential role and can be described as the crucial bread and butter of the South African economy. They have the potential to create employment and skills development opportunities pertinent for sustainable economic growth. The unfortunate part is that South African Small to Medium sized Enterprises have the lowest survival rates in the world, resulting in high rates of business failure and job losses. This is because the South African economy does not favour SMEs, which are often burdened with structural hurdles including access to funding, lack of access to markets, inadequate skills, uncompetitive regulatory frameworks and technological disruptions. A developing economy such as South Africa cannot grow if companies facing financial difficulty are constantly liquidated. This is because the liquidation system does not offer companies an opportunity to restructure and possibly function within the context of raised concerns. In order to facilitate sustainable SMEs growth, the legislature has come up with statutory mechanisms to support SMEs and save them from total liquidation. Most recently, the Companies Act 71 of 2008 Chapter 6 introduces a business rescue mechanism applicable to all business structures established under the Act. The purpose of business rescue is to provide companies in financial distress with opportunities to reorganise, strategize and come up with useful corporate reorganisation measures which are useful and efficient in saving the financially distressed company and possibly yielding a better return for the creditors than would have been the case if the company was liquidated. This new enactment is seen as both an improvement and necessary reform from its predecessor, judicial administration which has widely been condemned as a failure. However, despite this improvement, the application of the current business provisions to SMEs is questionable. Although Chapter 6 of the Act makes provision for SMEs, it also presents a number of stumbling blocks, including the fact that services of business rescue practitioners are out of reach for most SMEs in South Africa. The purpose of this study is to consider challenges faced by SMEs in the practical application of the current business rescue provisions. This study further emphasizes the importance of South African SMEs, whilst looking at their challenges and how the Companies Act 71 of 2008 provisions, regarding business rescue, assists SMEs. The study looks at the impediments of certain provisions of business rescue and proposes recommendations. , Thesis (MA) (Laws) -- University of Fort Hare, 2021

- Description: The epidemic of overweight or obesity conditions has become a public health concern in South Africa, and signifies major challenges of chronic diseases affecting the healthcare sector. Recent years have noted the increasing prevalence of gamification and development across all age groups. The rapid adoption and use of gamification as a tool to improve adult motivation and engagement when monitoring their health and wellness is an essential form of health intervention. Gamification allows its users to keep track of their health in real time and encourages an active healthy lifestyle behaviour. Research has found that there are factors that may inhibit the behavioural intention of adults to use gamification for health monitoring in the long term. These factors include cost or membership fees associated with gamification that uses Discovery Vitality and privacy concerns. The main aim of this research study was to develop a framework to influence the behavioural intention of adults to monitor their health through gamification making use of Discovery Vitality as the case study. The self-determination theory was used as the theoretical framework to ensure continuance usage of gamification for sustained health monitoring. A qualitative research approach was chosen for this study. The purposive sampling technique was selected to identify 20 adults between the ages of 18-59 years that are members of Discovery Vitality in East London, South Africa. Interviews were conducted with the 20 participants to identify the factors that will influence their behavioural intention to make use of gamification to monitor their health. After data collection, thematic analysis was used to analyse the data and the data provided by the participants was organised and summarised into relevant themes to answer the main research question. The study developed a framework which incorporated the four constructs of the self-determination theory, namely perceived autonomy, competence, relatedness and satisfaction of basic psychological needs for sustained health monitoring. The study also developed the five factors influencing the behavioural intention of adults to continue using gamification for sustained health monitoring. These factors are known as: broad appeal, applicability and accessibility through mobile technology and pervasive sensors, development and accomplishment, employment of creativity and feedback, and lastly social influence and relatedness. The recognition of weight loss, tracking and monitoring of physical activities and medication adherence was found to positively influence the behavioural intention of adults to continuosly use gamification to monitor their health. , Thesis (MCom) (Information Systems) -- University of Fort Hare, 2021

- Description: Female Genital Mutilation (FGM) is still rampant in many Kenya communities, especially the Maa and the Pokot speaking people, despite communication strategies and programmes instituted to eradicate the cultural practice. Female Genital Mutilation is a procedure that intentionally alters or cause injury to the female genital organs for non-medical reasons. The gains of eliminating FGM resulted from robust communication strategies introduced by the United Nations and the Kenyan government to educate and raise consciousness regarding the dangers of FGM practice. However, despite widespread communication efforts worldwide, at least thirty-one countries are still practising FGM. West Pokot County in Kenya has an 86% rate as a county that still practices FGM. The statistics are an indication that communication alone cannot achieve the desired goal as long as the communities feel that these organizations and their communication expects are looking down upon their culture, beliefs and practices. As far as FGM is concerned, attitude change is vital in communities to understand the dangers. Members of communities are often left behind or not consulted when developing strategies for eradicating FGM. Emphasis should be drawn on the involvement and ownership of such development programmes. Lack of participation from the communities seems to be the key reason for the failure of the campaigns to encourage people into deserting FGM practices. Therefore, this study evaluated communication strategies and explanations of why there is still a high level of FGM practice regardless of the prevalent consciousness of the consequences of its continued practice in West Pokot County, Kenya. This study adopts a mixed methodology (qualitative and quantitative) research approach. Convenience and purposive non-probability sampling techniques were subsequently used to select samples for this study. In-depth interviews and focus group discussions were held with the different community members in West Pokot County. There were five focus groups with nine participants in each focus group, making 45 participants for the focus group discussions. The collected data were interpreted and analysed thematically. This research showed a remarkable disparity between the community members ranging from their opinion and perceptions on the best and effective modes of communication to eradicate female genital mutilation and an alternative rite of passage. Another critical finding of this study indicated that beads of bondage linked to the community sanctioned rite of passage are another traditional practice that is endangering the lives of the girl child in Lokornoi, West Pokot County. Hence, this study proposed using mass media (newspapers, radio, television) using their vernacular language, which they understand and other interpersonal communication strategies (elders, chiefs and religious leaders) to eradicate FGM. Also, communication groups can involve communities to encourage a sense of ownership, which was the biggest reason for the communities to resist leaving FGM practice. This research suggests a need to develop alternative ways of communicating the message and that interpersonal channels are necessary to eradicate FGM in Kenya. , Thesis (MSoc Sci) (Communication) -- University of Fort Hare, 2021

- Description: The study aimed at investigating the management of students’ residential records at University of Fort Hare (UFH) and Rhodes University (RU). The objectives of the study were to: Investigate the residential policies and records management policies of the University of Fort Hare and Rhodes University; Assess the records management practices at the University of Fort Hare and Rhodes University; Determine how records management affects the process of allocating accommodation to students at the University of Fort Hare and Rhodes University; Identify areas of possible improvement of records management and student satisfaction concerning accommodation and allocation in both institutions. To achieve these objectives, the study used both qualitative and quantitative research methodologies. The data were collected using self-administered questionnaires and face-to-face interviews. A purposive non-probability sampling technique was used to select the participants of the study. Out of the targeted sample size of 39, the researcher administered questionnaires to 29 respondents and only 28 questionnaires were returned while 10 participants were interviewed. Therefore, a total of 38 staff members were included in the study. The qualitative data collected was analysed using thematic analysis while quantitative data collected was analysed using descriptive statistical analysis. The findings of the study showed that UFH and Rhodes University mostly make use of capturing process as one of the essential processes of records keeping used to allocate accommodation to students in their institutions. More importantly, the findings also revealed that there are different challenges faced by both universities. One of the challenges hindering student residence records at the University of Fort Hare (UFH) includes a lack of records xv management knowledge and incompetence. This might be because there are no records management personnel to take responsibility for student records. On the other hand, Rhodes University is faced with the unavailability of information sources, which might be attributed to a lack of information technology. , Thesis (MLIS) -- Faculty of Social Sciences and Humanities, 2021

- Description: Maize is the most essential cereal crop grown in Zimbabwe. This crop is produced across the country under different conditions and environments. The study focused on analyzing technical efficiency of A1 smallholder maize farmers in Chegutu and Zvimba districts under the Command Agriculture Scheme. Understanding technical efficiency is essential under developing agriculture, especially where resources are limited, and high population growth is quite common. In such a setting, increased output depends on efficiency improvements. The specific objectives of the study focused on estimating the level of technical efficiency, determinants of technical efficiency and the level of productivity among a randomly selected sample of 240 A1 smallholder maize farmers under the Command Agriculture Scheme. Purposive, cluster and random sampling techniques were used to collect primary data from the selected sample. The study applied the single-stage modelling stochastic frontier approach to assess technical efficiency of A1 smallholder maize farmers. The stochastic frontier results revealed that A1 smallholder farmers in Chegutu and Zvimba districts are technically efficient at 85 percent and 94 percent, respectively. The major determinants of technical efficiency varied across each district. In Chegutu district, major determinants of technical efficiency were basal fertilizer, labour and area of land cultivated for maize production, and all indicated a positive relationship with level of significance less than 10 percent and 1 percent (0.012, 0.000 and 0.000) respectively. In Zvimba district, major determinants of technical efficiency were basal fertilizer, topdressing and area of land cultivated for maize production, and all indicated a positive relationship with level of significance less than 5 percent, 10 percent and 1 percent (0.002, 0.021, 0.000) respectively. The study further estimated determinants of technical inefficiency. Main determinants of technical inefficiency in Chegutu district were age, maize farming experience and level of education. In Zvimba district, main determinants were maize farming experience, level of education, marital status, occupation status and other sources of income. The return to scale that measures the productivity level of farmers varied among the two districts in which farmers from Chegutu district had increasing returns to scale (1.43), whilst famers from Zvimba district had decreasing returns to scale (0.54). The study, therefore, argues that despite observed high technical efficiencies, Chegutu farmers could bridge their 15 percent gap between their observed output and the frontier output by focusing more on input usage with increasing returns to scale (1.43 percent). On the other hand, Zvimba farmers could bridge their 6 percent gap between their observed output and frontier output by focusing more on socio-economic drivers of technical inefficiency, given the decreasing returns to scale of their inputs (0.54 percent). , Thesis (MSc) (Agricultural Economics) -- University of Fort Hare, 2021

- Description: Maize is the most essential cereal crop grown in Zimbabwe. This crop is produced across the country under different conditions and environments. The study focused on analyzing technical efficiency of A1 smallholder maize farmers in Chegutu and Zvimba districts under the Command Agriculture Scheme. Understanding technical efficiency is essential under developing agriculture, especially where resources are limited, and high population growth is quite common. In such a setting, increased output depends on efficiency improvements. The specific objectives of the study focused on estimating the level of technical efficiency, determinants of technical efficiency and the level of productivity among a randomly selected sample of 240 A1 smallholder maize farmers under the Command Agriculture Scheme. Purposive, cluster and random sampling techniques were used to collect primary data from the selected sample. The study applied the single-stage modelling stochastic frontier approach to assess technical efficiency of A1 smallholder maize farmers. The stochastic frontier results revealed that A1 smallholder farmers in Chegutu and Zvimba districts are technically efficient at 85 percent and 94 percent, respectively. The major determinants of technical efficiency varied across each district. In Chegutu district, major determinants of technical efficiency were basal fertilizer, labour and area of land cultivated for maize production, and all indicated a positive relationship with level of significance less than 10 percent and 1 percent (0.012, 0.000 and 0.000) respectively. In Zvimba district, major determinants of technical efficiency were basal fertilizer, topdressing and area of land cultivated for maize production, and all indicated a positive relationship with level of significance less than 5 percent, 10 percent and 1 percent (0.002, 0.021, 0.000) respectively. The study further estimated determinants of technical inefficiency. Main determinants of technical inefficiency in Chegutu district were age, maize farming experience and level of education. In Zvimba district, main determinants were maize farming experience, level of education, marital status, occupation status and other sources of income. The return to scale that measures the productivity level of farmers varied among the two districts in which farmers from Chegutu district had increasing returns to scale (1.43), whilst famers from Zvimba district had decreasing returns to scale (0.54). The study, therefore, argues that despite observed high technical efficiencies, Chegutu farmers could bridge their 15 percent gap between their observed output and the frontier output by focusing more on input usage with increasing returns to scale (1.43 percent). On the other hand, Zvimba farmers could bridge their 6 percent gap between their observed output and frontier output by focusing more on socio-economic drivers of technical inefficiency, given the decreasing returns to scale of their inputs (0.54 percent). , Thesis (MSc) (Agricultural Economics) -- University of Fort Hare, 2021

- Description: The objective of this study was to determine the chemical composition and in vitro ruminal dry matter degradation (DMD) of Vachellia karro leaf meal-containing diets and their effect on feed intake and physiological responses of indigenous Xhosa lop-eared goats. Experimental diets containing 0 percent (Treatment 1), 15 percent (Treatment 2) and 30 percent (Treatment 3) Vachellia karroo leaf meal were mixed with grass hay and crushed maize. Samples of each diet were analysed for chemical composition and in vitro ruminal DM degradability. A total of 18 eight-month-old indigenous Xhosa lop-eared goats, initially weighing 20.81 ± 1.83 kg were randomly assigned to each diet in a Completely Randomized Design. The goats were confined in individual well-ventilated roofed pens and each dietary treatment had a total of 6 goats. The feed was offered at a rate of 3 percent of live weight twice a day, at 08:00 in the morning and at 16:00 in the afternoon. The experimental feeding trial lasted for 80 days, where 10 days was allowed for adaptation. Goat live weight, Average daily feed intake (ADFI), and Body condition scores (BCS) were recorded weekly FAMACHA scores and fecal eggs counts were also determined weekly. Blood samples were collected via vein puncture on the last day of the feeding trial for determination of glucose, total cholesterol, albumin and blood urea. Significantly higher (P < 0.05) crude protein (CP) and condensed tannins (CT) levels were observed in Vachellia karroo containing diets., while acid detergent fibre (ADF) and neutral detergent fibre (NDF) were significantly higher (P < 0.05) in the control diet. During early hours of incubation, DMD was similar (P > 0.05) across all dietary treatments. At 12 to 72 hours, the DMD was significantly higher (P < 0.05) in Vachellia karroo containing diets except at 48 hours. Correlation between DMD and NDF, ADF and fat was only visible at 24 hours. Fibre (ADF and NDF) were negatively related to DMD, while fat was positively related. A positive correlation was observed between DMD and DM, CP and ADFI. The body weight and BCS of goats was similar (P > 0.05) in all dietary treatments (P > 0.05). The ADFI was significantly higher (P < 0.05) in Vachellia karroo supplemented goats. Faecal egg count and FAMACHA scores were significantly higher (P< 0.05) in the control group compared to the Vachellia karroo supplemented treatments; while glucose levels were significantly higher in goats supplemented with Vachellia karroo compared to non-supplemented goats. Cholesterol levels were similar (P > 0.05) across all experimental groups. Goats consuming 30 percent of Vachellia karroo leaf meal had higher (P < 0.05) creatinine levels than the non-supplemented treatment. Urea levels were significantly higher (P < 0.05) in goats fed 30 percent of Vachellia karroo leaf meal than other treatments. It was concluded that the inclusion of Vachellia karroo leaves improves diet quality, diet degradability, average daily feed intake and physiological responses. , Thesis (MSc) (Animal Science) -- University of Fort Hare, 2021

- Description: Beef breeds of cattle are predominantly raised through extensive grazing and produce the highest levels of enteric methane (CH4) through ruminal fermentation. The objective of this study was to evaluate the effect of breed, grazing, and age on enteric methane production and performance of beef cows as well as effect of breed and grazing system on ruminal fermentation parameters. Two separate studies were conducted; the first study evaluated the effect of grazing system, breed, and age on ruminal enteric methane production and performance of selected beef breeds. The second study evaluated the effect of the grazing system and breed on ruminal fermentation. In the first study, two breeds (Nguni and Bonsmara) raised under two grazing systems (communal and commercial) in a random complete block design were grouped into 3 age categories. Eighty-four cows aged between 24-120 months were randomly selected and grouped by age: group A (young adult cow, n = 7, 24-48 months old), group B (adult, n = 7, 60-80 months old), and group C (old adult, n = 7, 90-120 months) in either grazing system. Data were collected on methane production per day, body condition, and weight used to estimate dry matter intake (DMI), methane per DMI, and methane per body weight. In the second study, 40 cows of the same age group, parity, and physiological status were used. Ten cows per breed (Bonsmara and Nguni) in either grazing system (communal and commercial) were used in a random complete block design. Rumen fluid collection was done by the stomach tube method. Data were collected on ruminal ammonia-nitrogen (NH3-N), pH, Temperature, volatile fatty acids (VFAs). Older animals produced higher methane per head in the order of C > B > A; (P<0.0001). Performance parameters like Body condition score (BCS), body weight (BW), dry matter intake (DMI), and daily methane were higher (P<0.05) in Bonsmara. However, Methane per BW was higher in Nguni (P<0.05), and methane per DMI did not differ among breeds (P>0.05). Body condition, BW, and DMI were higher (P<0.05) in commercial grazing system. Contrary, daily methane production, methane production per DMI, and methane produced per BW were higher in communal grazing. In the second study, Ruminal NH3-N concentration ranged between 69.05 - 96.78 mg/L and was higher (P<0.05) in Nguni. It was also higher (P<0.05) in the commercial grazing system. Ruminal pH, temperature, total VFAs, and certain individual VFAs (iso-butyrate, valeric and iso-valeric) did not differ (P>0.05) among breeds and grazing systems. However, total VFAs were slightly lower in communal grazing (78.87 mmol/L) than commercial grazing (89.80 mmol/L). Acetate, propionate, butyrate proportions, and acetate to propionate ratio did not differ (P>0.05) among breeds but differed (P<0.05) between grazing systems. Acetate (P<0.05) and acetate to propionate ratio (P<0.05) were higher in the communal grazing system, while the reverse was true for propionate (P<0.05) and butyrate (P<0.05). Bonsmara produced more methane than Nguni under similar conditions, with Nguni uniquely producing more methane per BW, indicating host genetics influence. Communal animals and older animals produced more CH4 than commercial and younger cows regardless of the breed, indicating ruminal inefficiencies in very old cows. These results emphasize the idea that host genetics or breed, grazing system, and age influence methane output and performance. Hence, breeding strategies for hard-to-measure traits like methane production need to put all these factors into consideration. , Thesis (MSc) (Animal Science) -- University of Fort Hare, 2021

- Description: Boophone disticha (L.f.) Herb. is a bulbous plant native to southern African areas of the continent and spreads to tropical Africa. The plant has been noted in literature for its high toxicity and has a long lineage of its use in traditional medicine for the treatment of various diseases. Due to high demand in the conventional trade market, the plant's conservation status has been shown to be declining. The plant has been reported to cause human poisoning, which can lead to death, but the plant is still administered by an indigenous community to treat various diseases. This study investigated the therapeutic potential of B. disticha used by the people of Raymond Mhlaba municipality to show and verify its use in traditional medicine and how it can be used as a possible drug ingredient. This study was also set out to investigate the anti-mycobacterial activity of the plant for the first time for the B. disticha growing in the Eastern Cape region of South Africa. The phytochemical analysis of B. disticha was carried out on four different plant parts (i.e., roots, leaves, bulb inner and outer scales) and the plant was extracted using methanol and distilled water. The qualitative phytochemical analysis displayed the presence of tannins, flavonoids, phenols and alkaloids in all plant parts for both extraction solvents. Anthraquinones were absent in all the plant extracts. The detected phytochemicals (tannins, flavonoids, phenols and alkaloids) were quantified. The roots had the highest phytochemical content for methanol extract for each phytochemical tested [439.67±1.53 mg/g (QE) flavonoids, 2414.67±1.53 mg/g (GAE) phenols and 527.33±2.08 mg/g (GAE) alkaloids] compared to all the plant parts. Methanol extracts from B. disticha revealed highest phenolic contents (2414.67±1.53 mg/g GAE) for the roots, 1395.33±2.52 mg/g (GAE) for the bulb inner scales, 1560±1 mg/g (GAE) for the leaves and 1550.7±18.9 mg/g (GAE) for the bulb outer scales). The total flavonoid content of the bulb outer scales aqueous extract was not detected. The presence of significant amounts of phytochemical compounds indicates that B. disticha has a higher medicinal value and can be extensively investigated to extract bioactive ingredients that are useful to the society, and that could be sold for higher production than using synthetic drugs with side effects. The antimicrobial activity of B. disticha extracts (methanol and distilled water) was evaluated using micro-dilution bioassay in 96-well micro-plates against nine disease-causing bacterial strains (5 Gram-negative and 4 Gram-positive) and three fungal isolates. The results revealed that methanol and aqueous extract of B. disticha demonstrated very good activity, with Gram-positive strains being more sensitive than Gram-negative ones. Boophone disticha aqueous extracts displayed the best activity against Staphylococcus aureus with MIC and MBC values ranging from 0.39 to 0.78 mg/ml. The methanolic extract of B. disticha leaves and outer scales of bulb displayed good activity against Klebsiella pneumoniae at MIC 0.78 mg/ml. The methanolic extract of B. disticha bulb outer scales also displayed good inhibition against Proteus vulgaris at MIC 0.78 mg/ml, with the root extract exhibiting activity against Shigella flexineri (MIC value of 0.078 mg/ml). Concerning antifungal activity, B. disticha extracts showed very poor inhibition properties against the fungal isolates. Anti-mycobacterium potential of B. disticha extracts (methanol and distilled water) was evaluated using micro-dilution bioassay in 96-well microtiter plates. The plant parts tested were the roots, bulb inner scales, leaves and the bulb outer scales. The highest activity against Mycobacterium tuberculosis was observed with the root methanol extract at MIC 0.78 mg/ml. The anti-inflammatory properties of B. disticha were investigated using the 5-lypoxygenase (5- LOX) assay. The overall anti-inflammatory activity results for the B. disticha extracts were poor; at low concentrations, the plant displayed negative results. The leaves methanol extracts did show little activity at 0.4 mg/ml. , Thesis (MSc) (Botany) -- University of Fort Hare, 2021

- Description: Background: Cancer burden is a global public health concern. It is associated with high morbidities and mortalities worldwide. Over the past decade, there has been a constant increase in the incidence of cancer cases affecting mostly low-income countries and middle- income countries. South Africa as a middle-income country is also affected by this cancer rise. The limited access to oncology services contributed to the late presentation and late diagnosis. In the Eastern Cape, oncology services were previously offered in Port Elizabeth and East London only. Oncology unit was recently opened in Mthatha to decentralize oncology services in the province. The purpose of the study was to explore the experiences of patients with cancer regarding decentralization of oncology services at a public tertiary hospital in the Eastern Cape province of South Africa. Objectives were to describe experiences of patients with cancer regarding decentralization of oncology services at a public tertiary hospital in the Eastern Cape, and to describe the quality of oncology services provided by a public tertiary hospital in the Eastern Cape. Methods: a qualitative research approach with a descriptive, explorative, and contextual design was undertaken in this study, to get the perspective of the oncology healthcare service recipients on the decentralization of oncology services at a public tertiary hospital. An interview guide was used to get experiences of the cancer patients attending oncology clinic. Interviews were conducted to 19 participants on a one-to-one basis. With ethical consideration, all COVID-19 protocols were observed. All interviews were transcribed carefully against their audio-recordings. Field notes were also taken by the researcher on what was heard, observed, thought and experienced during the interview process. The concept of trustworthiness was used to ensure rigour throughout this study. Data was analysed by means of thematic analysis. Data was organized into themes using the Tesch’s approach to open coding in qualitative research. Results: seven themes emerged: 1) experience related to a high level of satisfaction with services provided and desired expectations, 2) waiting time, 3) availability of human and material resources, 4) attitude of health care workers, 5) appropriate treatment and care, 6) access to services, and 7) need for improved infrastructural facilities Many patients had positive experiences about decentralization of oncology services in the province. Most patients were happy about travelling short distances, a smaller number of days, using less money and the time it takes to see a doctor. They also expressed their satisfaction on the quality of oncology services rendered in the unit. The waiting times were acceptable, medicines available and staff had positive attitudes towards the patients. The study revealed that, there were complaints about infrastructure, poor hospital record keeping, and lack of resources. The themes which emanated from the recordings of the study showed that patients with cancer, attending oncology clinic at a public tertiary hospital had positive experiences in this decentralized oncology unit. The services rendered at the facility were of acceptable quality. Staff had positive attitude towards their patients. All patients were seen by the doctors within acceptable waiting time, and they all got their prescribed medication. Access to services was much improved in terms of distance, number of days travelled by patients to access the service and time taken to see the doctor for appointments. Conclusion: The hospital must improve its infrastructure, record keeping, security, and expand the services. Put more focus on cancer awareness programs. , Thesis (MPA) -- Faculty of Health Sciences, 2021

Objectives were to describe experiences of patients with cancer regarding decentralization of oncology services at a public tertiary hospital in the Eastern Cape, and to describe the quality of oncology services provided by a public tertiary hospital in the Eastern Cape. Methods: a qualitative research approach with a descriptive, explorative, and contextual design was undertaken in this study, to get the perspective of the oncology healthcare service recipients on the decentralization of oncology services at a public tertiary hospital. An interview guide was used to get experiences of the cancer patients attending oncology clinic. Interviews were conducted to 19 participants on a one-to-one basis. With ethical consideration, all COVID-19 protocols were observed. All interviews were transcribed carefully against their audio-recordings. Field notes were also taken by the researcher on what was heard, observed, thought and experienced during the interview process. The concept of trustworthiness was used to ensure rigour throughout this study. Data was analysed by means of thematic analysis. Data was organized into themes using the Tesch’s approach to open coding in qualitative research. Results: seven themes emerged: 1) experience related to a high level of satisfaction with services provided and desired expectations, 2) waiting time, 3) availability of human and material resources, 4) attitude of health care workers, 5) appropriate treatment and care, 6) access to services, and 7) need for improved infrastructural facilities Many patients had positive experiences about decentralization of oncology services in the province. Most patients were happy about travelling short distances, a smaller number of days, using less money and the time it takes to see a doctor. They also expressed their satisfaction on the quality of oncology services rendered in the unit. The waiting times were acceptable, medicines available and staff had positive attitudes towards the patients. The study revealed that, there were complaints about infrastructure, poor hospital record keeping, and lack of resources. The themes which emanated from the recordings of the study showed that patients with cancer, attending oncology clinic at a public tertiary hospital had positive experiences in this decentralized oncology unit. The services rendered at the facility were of acceptable quality. Staff had positive attitude towards their patients. All patients were seen by the doctors within acceptable waiting time, and they all got their prescribed medication. Access to services was much improved in terms of distance, number of days travelled by patients to access the service and time taken to see the doctor for appointments. Conclusion: The hospital must improve its infrastructure, record keeping, security, and expand the services. Put more focus on cancer awareness programs. , Thesis (MPA) -- Faculty of Health Sciences, 2021

- Description: Background: Cancer burden is a global public health concern. It is associated with high morbidities and mortalities worldwide. Over the past decade, there has been a constant increase in the incidence of cancer cases affecting mostly low-income countries and middle- income countries. South Africa as a middle-income country is also affected by this cancer rise. The limited access to oncology services contributed to the late presentation and late diagnosis.

- Description: This study aimed to explore the experiences of unmarried fathers who are denied access to their biological children among amaXhosa communities in Mqanduli, Eastern Cape Province. This study also endeavoured to answer the following research questions: (i). what are the challenges encountered by unmarried fathers who are denied access to their biological children among amaXhosa communities in Mqanduli, Eastern Cape Province? (ii). what are government official's perceptions on experiences of unmarried fathers who are denied access to their biological children among amaXhosa communities in Mqanduli, Eastern Cape? (iii) What are the implications of denial of access of unmarried fathers to their biological children among amaXhosa communities in Mqanduli, Eastern Cape Province? This study adopted a qualitative approach within a phenomenological case study research design. A sample of forty participants comprising twenty unmarried biological fathers, seven statutory social workers, three presiding officers of children's court and ten cultural custodians was interviewed. The study revealed the following challenges: payment of pregnancy damages and bride price, unemployment, conflict with the maternal family, poverty, psycho-emotional breakdown, cultural responsibilities, terminated intimate partner relationship with the mother of the child, financial constraints, and lack of emotional and moral intelligence. The study recommends the development of a new 'family policy' to ensure integration of customary cultural practices and the legislative frameworks to provide a detailed parental-document to assist the new generation of parents in maintaining good parenting relations. Further, the study recommends the establishment of champions against absent and uninvolved fathers, where young men will explore fatherhood roles and develop educational and preventative strategies. , Thesis (MSW) -- Faculty of Social Sciences and Humanities, 2021

- Description: This research study was motivated by the fact that little is known about the topic and that older persons living in Mdantsane Township are heavily reliant on public transport such as taxis, trains, mini-taxis and buses which are, arguably, not suitable for transporting older persons. Through this research project, the researcher hoped to provide information which may contribute to better understanding of this phenomena, identify barriers in the transport system and get a better understanding thereof. This study utilized a qualitative research approach with an exploratory research design. Semi-structured interviews were used to collect data from 30 elderly persons living in Mdantsane Township, and thematic analysis was used to analyse data. Three themes and sub-themes were generated and later linked to the research questions namely: What are the experiences faced by older persons in using public transport? How do these experiences and challenges affect the quality of life of older persons using public transport? What do older persons view as potential barriers in using public transport? The findings highlighted that elderly people living in Mdantsane Township rely on public transport for participation in social and economic activities of the community as well as access to essential services. Consequently, lack of sufficient income among older persons affect their quality of life in relation to using public transport in that they cannot access all the services they need. They also indicated that there are several barriers for older persons against using public transport which include, concerns about personal safety, safety of items, public transport running late, behaviour of younger passengers and taxi conductors and lack of cleanliness among some drivers, to name a few. , Thesis (MSoc Sci) (Social Work) -- University of Fort Hare, 2021

- Description: Globally, food security is under threat from escalating population growth, new variants of diseases, climate change and livestock loss. Africa is vulnerable to food insecurity, with majority of the estimated 800 million suffering from hunger based in Africa. Intensification of production is a common strategy to counter the increasing demand for nutritional food to maintain and improve food security. The dairy industry is one of the leading agriculture sectors that has adopted intensification of production. The current study had two specific objectives; the first objective was to evaluate the dairy farmworkers’ knowledge and attitude towards mastitis, culling, and mortality in the southern part of the Eastern Cape Province. The data was collected from 106 dairy farm workers of different farm hierarchy in 5 out of 6 districts using questionnaire. In cases whereby a majority correctly answered a question, a point was awarded and a zero for incorrectly answered questions by the majority. A less than 50 percent pass rate was considered a poor level of knowledge, 51-69 percent pass rate was considered an average level of knowledge, and anything higher than that considered a good level of knowledge. The majority of the participants (64.2 percent) indicated that they consume unpasteurised milk even though they know its risks. There was no association (P>0.05) between workplace position, educational level, work experience, and consumption of unpasteurised milk. This study found that participants had a deficient level of knowledge of mastitis causing pathogens by attaining a pass mark of 1.60 out of a possible 10 (16 percent), and educational level was significantly associated with knowledge of Escherichia coli, Staphylococcus aureus, and Streptococcus spp. However, the participants (64.9 percent) showed good knowledge of clinical signs of mastitis, and this was attributed to the regular mastitis detection with California Mastitis Test (CMT, 60.4 percent) and a strip cup (83.0 percent). The participants had varying perceptions and limited knowledge (28.3 percent pass rate) about the major contributing factors of culling and mortality. The lack of dairy training courses and minimal use of other sources of information such as the internet might contribute to this poor knowledge and perceptions. The second objective involved identifying and describing the factors responsible for culling and mortality in dairy farms in the Eastern Cape province, South Africa. The factors were grouped into seven (7) major factors namely lameness and poor growth (2.33 percent), reproduction problems (35.86 percent), health factors (6.72 percent), production factors (7.11 percent), udder-related factors (3.42 percent), voluntary culls (4.86 percent) and miscellaneous factors (26.03 percent). The most frequent reason for culling dairy cows was reproduction problems which was mainly made up of infertility (7.9 percent), reproductive failure (89.9 percent), and dystocia (1 percent). Miscellaneous factors which mainly consisted of indigenous breeds (8.2 percent), and age (2.7 percent) accounted for the second most prevalent factors for the culling of dairy cows. All the farms recorded stock-theft as part of involuntary culling and accounted for 3.6 percent dairy cows that were culled. Poor milk yield and health-related factors such as red-water (33.8 percent), milk-fever (23.3 percent), and heart-water (6.8 percent) were amongst the major factors responsible for the culling of dairy cows. There were 1774 (13.67 percent) dairy cows that died in the study farms from 2015 to 2019 and causes of death were not specified except for drowning (0.01 percent) and snake bite (1 percent). This study exposed a gap in knowledge about the causes of mastitis, culling and mortality among dairy farmworkers in the southern part of the Eastern Cape Province. Furthermore, this study provided with a baseline information on the leading causes of culling and mortality. There is a need for further research on strategies of enhancing the knowledge of dairy farmworkers about pathogens of mastitis and specific causes of culling and mortality to mitigate the challenge they pose to food security. , Thesis (MSc) (Animal Science) -- University of Fort Hare, 2021
