- Description: Aggregate stability and aggregate size distribution on soil surface that is impacted by rain drops affect soil erosion yet little is known about less weathered coarse textured soils. The objectives of the current study were to determine (i) the aggregate stability and associated aggregate fraction size distribution and (ii) the impact of the initial aggregate size on the aggregate stability and the resulting sediment fraction size distribution following rain drop impact in some quartz dominated coarse textured soils in the Eastern Cape Province. Soil samples for this experiment were collected from 14 ecotopes on the surface with a natural slope between 7.5 to 11% and at the depth between 0 to 0.2 m in the Eastern Cape Province. In each ecotope, twenty-five different spots were sampled using a spade at depth 0 to 0.2 m in other to eradicate biasness and ensure homogeneity. Thereafter, the soil samples were mixed to make a composite sample. The composited soil samples were then placed in rigid containers and taken to the soil science laboratory of the University of Fort Hare, Alice Campus where analyses were carried out. The soil properties were determined by passing the < 5 mm soil sample through a 2 mm sieve. The total Na, Ca and Mg contents in the soil samples were also determined using the wet digestion with sulphuric acid method. The total Soil organic matter content (SOM) was determined by the process known as weight loss on ignition. Thereafter, the fraction size distribution and aggregate stability was done by passing < 5 mm soil samples through a 3 mm sieve. The obtained calibrated aggregates between 3 and 5 mm were oven dried at 40o C. Thereafter, five gram (5g) of oven dried calibrated aggregates was immersed in a 50 mL deionized water in a 250 mL beaker for 10 minutes. The soil material left was transferred to a 0.053 mm sieve already immersed in ethanol and moved five times in the ethanol to separate < 0.053 mm from > 0.053 mm fragments. The remaining > 0.053 mm was re-immersed in ethanol and further oven dried at 40o C for 5 minutes. Thereafter, the > 0.053 mm fraction was transferred from 0.053 mm sieve, oven dried at 40o C, dry sieved using Digital Electromagnetic Shaker on a six column of sieves: 2 mm, 1 mm, 0.5 mm, 0.25 mm, 0.106 mm, and 0.053 mm. The aggregate stability was determined using the resulting size distribution in seven classes by calculating the mean weight diameter (MWD, mm). The soils were very stable, moderately stable or unstable. The presence of smectite and cultivation as opposed to pasture lowered aggregate stability. The studied soils showed three different aggregate size distributions. Unstable soils were dominated by 0.106 – 0.25 mm aggregate size and showed a positively skewed aggregate fraction size distribution. Aggregates finer than 0.106 mm were limited because of the coarse nature of the soil texture. Moderately stable soils broke down to both micro aggregates, 0.106 – 0.25 mm and macro aggregates, 2 – 5 mm giving a bimodal distribution. The aggregate size distribution in the very stable soils was dominated by the aggregate fraction size 2 – 5 mm and a negatively skewed aggregate fraction size distribution. The smaller the initial aggregate size the higher was the aggregate stability but the reverse was true for splash erosion. It was thought that the short 5 minutes duration of the rainfall might not have been enough to cause a total breakdown of the aggregates. Alternatively, ecotopes that were dominated by primary soil minerals such as quartz showed different breakdown behaviour compared to those containing secondary minerals such as kaolinite or smectite.

- Description: The study took a qualitative approach to the analysis of the effect of the politics-administrative interface on municipal service delivery. It was a case study of the Mnquma local municipality in the Eastern Cape Province. The researcher developed a keen interest in researching on the topic because the political infighting and clashes between politicians and administrators of the municipality have caused a public outcry for the root causes of the infighting to be effectively addressed and redressed. It is hoped that the findings and recommendations of the study will help, reshape public policy implementation, service delivery and fostering of mutual cooperative relations between politicians and administrators both at local government level and any other sphere of government in South Africa. The study, is categorized into five chronological chapters, with chapter one (introduction and background), chapter two (literature review), chapter three (research design and methodology), chapter four (data analysis, interpretation and presentation) and chapter five (conclusions and recommendations). The researcher used a sample size of 40 respondents who were selected using snowball sampling, a non-random sampling design spread accordingly over both politicians and administrators. Data collection was made possible through an open-ended questionnaire, interviews, observations and documentary analysis. Various reports and media statements were also used to augment this empirical study. The study also used an in-depth qualitative data analysis technique which was descriptive in nature and the study made numerous deductions and findings based on the collected and collated data. Findings of the study were, inter alia, too much politicization of the public sector, interference between politicians and administrators into each other’s affairs and vice versa and adverse effects of cadre deployment which are damaging service delivery. The study made numerous recommendations which included, inter alia, training and development of administrators and politicians on their respective roles and responsibilities, enforcement of the politics-administrative interface as a mutually beneficial approach to service delivery, need for proper interpretation of Acts and policy documents and the enforcing of section 139 interventions into municipalities.

- Description: Since the dawn of democracy in 1994, South Africa has promulgated a number of progressive legislation and programmes in an effort to improve the well-being of its citizens. There is legislation and prescripts designed to provide policy and legal basis for a concerted and coherent pursuit of public participation in South Africa. There are various pieces of legislation that provide overarching principles and norms to guide the concerted enhancement of public participation in the local sphere of government. In spite of the plethora of policies and programmes, communities in various places continue to engage in service delivery protests. This study critically analyzed the implementation of public participation policy as a legislative core value for local government, with specific reference to Mbombela local municipality. In doing so, it critically explored the extent to which Mbombela local municipality involves the local communities in matters of local government such as in strategic decision making, the development of the IDP, performance management and in service delivery processes. The study employed a qualitative research methodology, relying mainly on secondary written sources of data, which reported on public participation and public administration. These sources include books, journals, internet sources, government legislation and policies. Data was also collected from Mbombela local municipality through interviews with municipal officials, members of ward committees, community development workers and the public. This study has found that Mbombela local municipality (MLM) relies primarily on ward committees, ward- based meetings and the Speakers outreach as mechanisms to facilitate public participation. The municipality seems to regard public participation as a crucial aspect in that a public participation unit was established; however the municipality is using a low level of participation, with limited power by citizens to influence strategic decisions. This means that communities and community organizations are involved on matters of the municipality only through attending community meetings therefore such meetings are not sufficient for effective public participation as communities should also be involved in more strategic and influential means such as participating in steering committees, development and economic forums. This study further found that some of the ward committees are not effectively functional as a result of lack of commitment from ward committee members, unavailability of some ard committee members due to their permanent job commitments and due to the difficulty that is caused by the vastness of some of the wards. This study also revealed hat there is no feedback provided to ward committees by the municipality on the ward committee reports that are submitted to the municipality on monthly bases, as a results some ward committee members are demotivated. This research study concludes that Mbombela local municipality is not effectively implementing local government legislation in respect to public participation.

- Description: This study was primarily carried out in order to assess the sexual risk behaviours of people living with mental illnesses as well as their vulnerability to HIV infection. It sets out the basic realities of the interaction between mental illness and HIV/AIDS and its impact on individuals and communities. This study explores the implications for health policy and practice, and suggests how to provide better support and assistance in the empowerment of people living with mental illness as far as HIV and AIDS is concerned, including community support. It was also the aim of this study to look into the factors that expose this group of people to HIV infection as well as to understand the link between HIV/AIDS and mental illness. It also tested the inclusion of people with mental disabilities in HIV and AIDS prevention and education programmes. The research was conducted on the basis of a qualitative research design. A semi-structured interview schedule was used in broad based interviews to gather information from caregivers or guardians of people with mental disabilities as well as the professionals in the mental health sector. The results of the research revealed that people who are living with mental illnesses are a vulnerable group as regards HIV infection. It also conveys that this group of people presents with sexual risk behaviours, which increase their vulnerability to HIV and AIDS. In addition, there are many barriers against the inclusion of this group of people in HIV and AIDS prevention and education programmes and, as a result, they are often excluded from participating in such programmes. Importantly, the findings of this study acknowledge that there is a two-fold relationship between mental illness and HIV/AIDS. It indicates that mental illnesses are still regarded as mysterious in the community and there is much stigma and discrimination towards the mentally ill, increasing their vulnerability to HIV infection. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2013

- Description: The study investigated local institutions amongst Agri-park project beneficiaries: A case of Dutywa Agri-park in Mbashe Local Municipality. Specifically, the dissertation sought to: investigate formal and informal institutions pertaining to land, rangeland management and support services, extension services amongst Agri-park beneficiaries, and explore options with communities to strengthen these institutions for the application of the Agri-park projects. The role of local institutions in economic development has received steadily increasing attention from researchers, policy makers and development practitioners. , institutions can be defined as the formal and informal rules of the game that have been formulated to rule people‟s behaviour and transactions. Informal rules may include among others, customs, norms and standards, religion, indigenous law while formal rules may include laws, constitutions, policies, markets and firms. This study used a survey design, quantitative and qualitative research methodologies involving the use of questionnaire. The data for this study was collected from 114 households which are Agri-park project beneficiaries, the extension officer, project site manager and local economic development officer. The data were collected through face to face and telephonic interviews. Institutional Analysis and Development (IAD) framework and Statistical Package for Social Sciences (SPSS version 20.0) were used for descriptive analysis in order to identify the existing local institutions and how they should be strengthen. The results showed that a number of local institutions do exist. The main findings of this study were as follows: (1) Project beneficiaries were aware of their stakeholders and that they knew the roles and responsibilities of each stakeholder in the project. (2) Traditional leaders were aware about the project and that they have a major role to play. (3) Project beneficiaries have organized themselves into groups of co-operatives and their co-operatives are registered with the Department of Agriculture. (4) Project initiators are going to transfer the ownership of the project to these communities after it becomes well established. (5) There was a mutual agreement of youth employment rotation in the project between these four communities. (6) The condition of lease agreement for a land where the project currently running is 9 months renewable contract with the rental payment of R 6300.00 per annum. (7) The lease agreement gives the church a property right to reclaim the land should payments not be made. (8) Project beneficiaries possess some agricultural skills and that they have received various training. The study recommended that there is a need to strengthen these rules and regulation for the project to become more efficient and productive in the long-run. , Thesis (MSc) -- Faculty of Science and Agriculture, 2013

- Description: Although Small and Medium Enterprises (SMEs), arguably, make up a significant part of economic development in many countries, these enterprises have continued to face challenges especially in developing countries like Kenya. With Information Technology (IT) being considered a critical component of the survival of SMEs, many are striving to invest in it. However, a number of these SMEs are still far from realising the full potential of their IT investments. In today‟s challenging and dynamic business environment, SMEs need to leverage both internal and external knowledge, exploit it to help improve and maintain their competitiveness, and consequently, their survival. This study has endeavoured to address the IT adoption strategy challenges experienced by SMEs in Kenya and other developing countries, as these have been largely flawed. The study has explored on the way in which these enterprises can build strong Absorptive Capacities (AC) and exploit these to improve their IT adoption processes through a model of AC. To achieve this, a qualitative, interpretive case study research approach was employed in this study. The findings of this study suggest that although AC plays a critical role in the performance of SMEs in Kenya, many of these enterprises have low levels of AC. It also became clear that all the SMEs that participated in the study had not attained maturity in their IT adoption process. However, SMEs that exhibited strong AC employed the use of more superior IT adoption processes than did their counterparts with low levels of AC. From the results of this study an IT Adoption Strategy Improvement Model (ITASIM) has been developed to help SMEs improve their IT adoption strategies. The model focuses on improving SMEs‟ AC and injecting these alongside the elements of a good strategy in the SMEs‟ IT adoption process. Furthermore, in order to help in the effective implementation of ITASIM, implementation guidelines have been developed.

The study was conducted after a realisation that despite not receiving much support from city by- laws, poor and low income households of Harare continue to engage in agricultural activities yearly. The desk research method was used to acquire information from a vast of secondary data sources. The secondary sources which were qualitative in nature provided the research with broad literature on urban agriculture and poverty in Harare, Zimbabwe and the world at large. However, a case study research design was employed whereby an in-depth analysis of the topic focused on poor and low income farmers of Harare Province. Literature reviewed and analysed was organised into themes and categories that portrayed urban agriculture as a crucial tool for alleviating poverty. It was also viewed as a tool that can be used as a sustainable livelihood. Despite other factors affecting the performance of urban farmers, lack of clear policies and city by- laws that guide agriculture in the study area proved to be a huge hindrance. Therefore, to achieve sustainable livelihoods and reduce poverty, the research suggested that instead of different pieces of city by- laws governing the practice in Harare and Zimbabwe there is need for one clear urban agriculture policy. It was concluded that the government and city authorities remain the key to unlocking UA‟s full potential by providing formal support to the practice by organising formulation of an inclusive urban agriculture policy that will be understood by every citizen.

- Description: The research attempts to investigate the effectiveness of coordination in the State Ministry of Cabinet Affairs (SMCA), Jonglei State government, South Sudan. The objectives of the study were to identify coordination functions of the state Ministry of Cabinet Affairs, challenges and its role in promoting ethics and good governance in service delivery in Jonglei State. Quantitative and qualitative data was collected from a sample of twenty one respondents which included the State Deputy Governor, Directors of SMCA and Secretariat through questionnaires and interviews. This explored the functions; roles; and its organizational hierarchy which promotes ethical delivery of services and good governance. The study further discusses the levels of the implementation processes and the possible challenges facing SMCA. The results of the study reveal that the SMCA lacks qualified staff, unclear job descriptions and as a result it impinges on coordination and implementation of strategic plans and service delivery within the directorates. The study therefore recommends that for effective and efficient service delivery in promoting ethics and good governance, training of the human resource, recruitment of competent staff, clear job descriptions, regular performance appraisal and effective communication among others are paramount. The study further recommends that gender equality and equity should be addressed in order to meet the Millennium Development Goals (MDGs) in the community.

- Description: Human trafficking is a social problem that has left no state or country immune to its effects. Literature indicates that human trafficking causes economic social and physical disruptions. Families are left broken and communities divided and children left homeless. Its victims are mostly women and children who come from low socio-economic status. Studies have been conducted on the roles of Non-Governmental Organisation`s across the globe but reports on the roles of NGOs in the Eastern Cape are unknown. This study reports on the roles of Non-Governmental Organisation`s (caregivers) in the Eastern Cape. This investigation is an exploratory qualitative study. A purposeful sampling strategy was used to recruit the Non-governmental organization (caregivers). In depth open ended interviews were conducted. The theories of Interpretative Phenomenological Analysis (IPA) and socio-ecological theory were used to discuss the findings of the study. The findings of the study were categorized into four main themes including; knowledge of human trafficking, causes of human trafficking, roles of non-governmental organization (caregivers) in the Eastern Cape and strategies available in the Eastern Cape Province. The findings showed that human trafficking is present in the Eastern Cape. Abused and neglected children are more likely to become potential victims of human trafficking. The caregivers play a huge vital role in the fight against human trafficking. Lastly, the strategies implemented are not as effective as they would have been if adequate legislation was passed against human trafficking.

- Description: This study investigated the relationship between SAPS performance management and measurement assessment patterns and public perceptions of the effectiveness of SAPS. The Performance Management System (PMS) and the Performance Measurement System (PMS1) of SAPS were investigated and it was looked at whether there is a correlation between them. The two internal measurement systems i.e. PMS and PMS1 were compared with the perception of the community about service delivery effectiveness of SAPS. Seven police stations in the Queenstown Cluster participated in the study. Semi-structured interviews were used to gather data from the Cluster Commander, Station Commanders, Production personnel and members of the community. The findings indicated that SAPS has challenges in implementing PMS. Matters of honesty and trust were seen as contributing factors to these challenges. The internal performance management tools do not take into consideration the needs of the community. This transpired on the results of internal performance management which indicated police stations and their members to be performing satisfactory while the community is not satisfied with the police station performance.

- Description: This study examines the impact of children’s grants on household access to food, education and health care. In the face of increased poverty and socio-economic inequalities, social grants are a critical poverty alleviation intervention implemented by the government of South Africa. The children’s grants are offered as part of the social security system which is provided for in the Republic of South Africa Constitution of 1996 and the Social Assistance Act of 2004. The basic needs conceptual framework is the lens informing the focus of the study. Among other major findings, the study reveals that (a) childrens grants play a critical role in improvement of access to food, health care and education, (b) childrens grants are used as collateral, to access short term loans, and (c) social networks and home gardens play a significant role in aiding children’s grants to ensure household access to food, education and health care.

- Description: The objective of the study was to determine sheep growth performance, fleece weights and wool quality characteristics in the sweet and sourveld communal rangelands of the Eastern Cape Province of South Africa. Data were obtained in 80 ewes aged two to three years, selected in four ecologically different communities. Two communities (Roxeni and Tyabane) were in a sweetveld area and the other two communities (Luzi I and Luzi II) were in a sourveld area. The ewes from Tyabane were nondescript, whereas ewes from Roxeni, Luzi I and Luzi II were crossbred between Merinos and non-descript sheep. Selected ewes were monitored for live weight, body condition scoring and fleece weight during shearing. Wool samples were collected from each ewe and were analysed for fibre diameter, comfort factor, clean yield, wool crimps, staple length, staple strength and the Position of break. Sheep from Roxeni were heavier (P <0.05) (39.9 ± 1.1kg) than sheep from Tyabane (29.8 ± 1.1kg). Sheep from Tyabane had the lightest (P <0.05) fleece weight (1.0 ± 1.1kg) and sheep from Roxeni had the heaviest (3.1 ± 1.1kg). There were no significant differences (P ≥0.05) between body condition scores of sheep in Roxeni and the Luzi communities. The live weights of the two-year old ewes were similar (P ≥0.05) to the three-year old ewes’ live weight. However, the three year old ewes had higher (P <0.05) body condition scores than the two year old ewes. Two year old ewes also had lower (P <0.05) fleece weight than the three years old ewes. Wool from Roxeni, Luzi I and Luzi II had lower fibre diameter (P <0.05) than wool from Tyabane. Roxeni sheep had the highest clean yield (P <0.05) of wool, followed by Luzi I and Luzi II; Tyabane had lowest clean yield percentage of wool. Wool from sheep grazing on sweetveld had a higher (P <0.05) clean yield percentage (74.3 ± 0.7%) than those grazing on sourveld (71.7 ± 0.7%). There were higher staple mid-breaks (69.5 ± 5.2) and lower base-breaks (30.5 ± 5.2) in sweetveld (P <0.05) than in sourveld, 7.5 ± 5.2 and 92.5 ± 5.2 for mid-breaks and lower base-breaks, respectively. It was concluded that sheep raised in the sweetveld and bred with purebred Merino rams had higher performance than the ones reared in the sourveld. The young upgraded ewes had a higher wool quality than the older ewes raised on communal rangelands.

- Description: This research study explored livelihood strategies that female headed households adopt in Magaso village of Mutoko district in Zimbabwe. The study intended to achieve the following objectives: (i) examine the existing livelihood strategies of female headed households (ii) explore the various challenges faced by female headed households and (iii) establish the support mechanisms in place for female headed households to cope with life challenges .The literature reviewed in the study was drawn from several researchers, and the study was shaped by the strengths perspectives and the liberal feminism perspective. The study was qualitative in nature and used interviews to collect data from fifteen (15) female headed households. The data collection process used an interview guide. The research employed a qualitative research design in the form of a case study cum a phenomenological study design. Data was analysed qualitatively using the content thematic data analysis which used interpretive approaches and presentation is textual rather than statistical. The study findings were the following: engaging in subsistence farming was found to be the main livelihood activity of the female heads; engaging in home gardens; exchanging labour for food; involvement in business; reliance on temporary employment from different agencies; reliance on handouts from government and other bodies; and household heads sanctioning child labour that compromises school attendance. Moreover, these female heads faced numerous difficulties ranging from emotional, social to financial problems that resulted in worsening the condition of women, and hence validating feminization of poverty among them. Several support mechanisms were discovered to be available for the female heads but they fail to produce to fruitful results to the lives of the female heads. The study made the following recommendations: mainstreaming gender education from childhood stage; efforts aimed at job creation; financial empowerment through setting up of micro schemes for rural women amongst; seeking the services of agricultural extension services to the female head farmers; improving the social services delivery in Zimbabwe equitably across genders and strengthening informal strategies to improve women‘s social capital. Lastly, the study concluded that little is being done in terms of policy formulation to make the support structures responsive to the female headed households especially in rural areas, hence the need for sustainable development through empowerment.

- Description: The main focus of this study is the challenges of rural tourism development in Zimbabwe. The study identified that there is a lack of sustainable interventions in the development of rural tourism which is catalyzed by the absence of rural tourism promotion strategy to support the sustenance of livelihoods through socio-economic transformation. Meaningful socio economic transformation in the African rural areas through tourism remains a major development challenge. Development initiatives through different forms of tourism in the rural communities, has to a less magnitude benefited the rural communities and have negatively impacted the socio–economic environment. A qualitative research methodology and case study design was employed in order to have a deeper understanding of the experiences of the society around this project. Face to face interviews and focus group discussions guides were used to collect primary data. Purposive and convenience sampling techniques was employed to select respondents. Data was analysed using the transformative theory and sustainable livelihoods theory and was organized into categories and themes. The study established that the absence of a strategy is caused by political instability, community conflict, lack of finance, marketing, poor communication, and limited knowledge of tourism. All the aforementioned reasons complement each other and poise a challenge to the sustainability of rural tourism development. For Zimbabwe to effectively transform its economy through tourism, the government needs to plan the process, formulate and implement relevant economic and social development strategies and policies. Although this dissertation is a case study of sustainable rural tourism in Zimbabwe, it can be used to appreciate the role of tourism in bringing about socio-economic transformation and sustaining livelihoods in developing countries.

- Language: English
- Type: Thesis , Masters , M Com (Business Management)
- Identifier: http://hdl.handle.net/10353/799 , vital:26498 , Small business -- South Africa -- Eastern Cape , Retail trade -- South Africa -- Eastern Cape , Liquor industry -- South Africa -- Eastern Cape , Social responsibility of business -- South Africa -- Eastern Cape , Liquor laws -- South Africa -- Eastern Cape
- Description: In the contemporary business environment, a plethora of retail literature exists which examine the influence of CSR on the business. However, literature that explores Corporate Social Responsibility (CSR) in the liquor retail sector has been relatively sparse. This study explored CSR in Small to Medium Enterprise (SME) liquor retail outlets in the Buffalo City Metropolitan Municipality, Eastern Cape, South Africa. The objectives of the study were to investigate the engagement of SME liquor retailers in CSR practices, to ascertain whether a relationship exists between providing employee training on responsible retailing of alcohol and CSR practices by SME liquor retailers, to investigate whether employee involvement in decision making influences CSR practices by SME liquor retailers, to ascertain whether a relationship exists between the practical actions to reduce alcohol-related harm and CSR practices by SME liquor retailers, to investigate whether SME liquor retailers do social good as an expression of CSR as well as to determine whether SME liquor retailers are influenced by stakeholders to engage in CSR initiatives. Both primary and secondary data sources were used in this study. A quantitative research design was used in conducting this research. Convenience sampling, a non-probability sampling technique, was used to select a sample of 94 from the sample frame of 123 SME liquor retailers. The survey method, by way of a self-administered questionnaire was used to collect primary data. The statistical Package for Social Sciences (SPSS) as statistical software was used to analyse data. The Chi-square test, Pearson correlation, and descriptive statistics were used to analyse data. The findings of this research revealed that Stakeholder influence, employee involvement in decision making and employee training in responsible retailing of alcohol have an influence on the CSR practices of SME liquor retailers. The study also identified the safety and practical measures that SME liquor retailers are practicing as a way of reducing alcohol related-harm. A recommendation to stakeholders, such as suppliers and government to find more strategies of influencing SME liquor retailers to practice CSR, was made. Lastly, recommendations were made to SME liquor owners and managers on how to improve their CSR practices.

- Description: Community development programmes as livelihoods strategies have been central to rural poverty eradication, development thinking and practice in the past decade. But where do such perspectives come from, what are their conceptual roots, and what influences have shaped the way they have emerged? This study offers a historical review of key moments in debates about sustainable community development programmes and rural poverty reduction, identifying the tensions, ambiguities and challenges of such approaches. A number of core challenges are identified in this study, centred on the need to inject a more thorough-going analysis into the centre of livelihoods perspectives. The study was done as a first step to identify, at a local level, evidence of the contribution of such programmes designated to tackle poverty in rural areas in Buffalo Municipality and to establish the challenges faced in providing sustainable livelihood outcomes. This will enhance the capacity of livelihoods perspectives to address key gaps in recent discussions, including questions of knowledge, politics, scale and dynamics. It is of utmost importance to note that funds per see cannot bring the rural poor out of their situation, rather as the study posits, continued support, empowering locals with ongoing training on marketing and how to run business, a culture of savings as well as the development of participatory monitoring and evaluation mechanisms can bring about reduction in poverty through sustainable community development programmes and eventually leading to eradication.

- Description: The objective of the study was to determine the feed conversion efficiency (FCE), carcass characteristics, physico-chemical quality, fatty acid (FA) composition and shelf life of pork from pigs fed diets containing either 0% (T1), 2.5% (T2), 5% (T3) or 7.5% (T4) Moringa oleifera leaf meal (MOLM). Consumer health-related perceptions on pork and fatty acids were also investigated. Twenty four crossbred Large White x Landrace pigs of both sexes at 18 weeks of age and initially weighing 71.6 kg on average were housed individually and had ad libitum access to one of the four dietary treatments for a period of six weeks. Average daily feed intake (ADFI) and average daily gain (ADG) and feed conversion ratios (FCR) were calculated as an indication of FCE and pigs were slaughtered at an average live weight of 99.6 kg. Carcass traits such as back fat thickness (BFT), carcass temperatures and pH readings taken 45 minutes and 24 hours (pH45 and pHu) post mortem were recorded. M. longissimus thoracis et lumborum (LTL) samples were taken from each carcass for the determination of lightness (L*), redness (a*), yellowness (b*), thawing loss percentage (TL%), cooking loss percentage (CL%), Warner Bratzler Shear Force (WBSF), shelf life and FA composition. Furthermore a survey was conducted amongst 80 University of Fort Hare Students to determine their health-related perceptions on pork and fatty acids as well as their pork consumption frequency using questionnaires. The FCE of pigs fed on 0-5% MOLM (T1, T2 and T3) diets did not differ significantly, but the FCE of pigs fed 7.5% MOLM (T4) was significantly (p<0.05) reduced. No significant relationship was reported between inclusion of MOLM carcass characteristics and physico-chemical pork quality. There was however a significant improvement (p<0.05) in the shelf life of the pork from MOLM fed pigs in terms of colour and odour during 10 days of refrigerated storage (at 3±1°C). There was a significant (p<0.05) reduction in the total intramuscular fat (IMF) content and the saturated fatty acid (SFA) C18:0 (stearic acid) content and an overall non-significant (p>0.05) increase in the poly unsaturated fatty acid (PUFA) content of pork from MOLM fed pigs. The possible reason for this is that the feeding of MOLM was commenced when the pigs were at an advanced age and weight. The survey revealed that the majority of interviewed students consume fresh (39.7%) and processed (32.4%) pork two to three times a week, perceive pork to be generally healthy (70%) and the second most healthy meat type (39.5%). While the majority (55.4%) were aware of the health implications of FAs they did not know which FA classes pose more of a health risk (51.3%). In conclusion2.5% and 5% of MOLM in finisher pig feed did not negatively affect FCE, carcass characteristics or physico-chemical meat quality; significantly improved pork shelf life and reduced total IMF and SFA content of pork but 7.5% MOLM negatively affected FCE; and the majority of students perceive pork to be the second most healthy type of meat and are generally aware of the health implications of FAs.

- Description: The increasing population and the rapid economic growth in South Africa have led to higher consumption of food resulting in the generation of large amounts of waste. In addition, South Africa has plenty of biomass from cattle, donkeys, horses, goats, pigs, chicken and sheep. However, anaerobic digestion could be an alternative solution for the utilization of these kinds of waste due to its environmental and economic benefits. Therefore, the main focus of the research was design, construct a field batch biogas digester, monitor its performance when fed with co-substrates and model the methane yield for an optimized mixing ratio.
