However, conception rate was not independent (P < 0.05) of provinces, body condition score and body frame size. Cows in KwaZulu-Natal (66 percent) had significantly higher (P < 0.05) conception rates than those in Limpopo (44 percent) and Mpumalanga (60 percent). Cows of body condition score of ≥ 3.5 (72 percent) had a significantly higher (P < 0.05) conception rate than those of body condition score of ≤ 2.5 (66 percent) and 3 (48 percent). Large (82 percent) framed cows had a significantly higher (P < 0.05) conception rate than small (49 percent) and medium (55 percent) framed cows. Cows in Mpumalanga had more chances to conceive than those of Limpopo and KwaZulu-Natal with odds ratio of 0.605 and 0.863, respectively. Cows in KwaZulu-Natal were in much better body conditions than those from the other two provinces. Cows of body condition score of ≥ 3.5 had more chances to conceive than those of body condition score of ≤ 2.5 and 3 with odds ratio of 0.592 and 0.388, respectively, and the difference was significant (P < 0.05). The study recorded a 100 percent calf survival rate following synchronisation and timed artificial insemination. The breed type, parity, age frame size and lactation status did not significantly influence calving response following oestrous synchronisation and timed artificial insemination (P > 0.05). However, calving rate was not independent of provinces, districts and body condition score (P < 0.05). Calving rate in Mpumalanga (58 percent) and KwaZulu-Natal (54 percent) was significantly higher (P < 0.05) than that recorded in Limpopo Province (36 percent). Calving rate of Gert Sibande (61 percent) and Ehlanzeni (50 percent) districts in Mpumalanga and Zululand (50 percent) and Harry Gwala (61 percent) in KwaZulu-Natal was significantly higher (P < 0.05) than that of the Capricorn (32 percent), Mopani (23 percent and Waterberg (30 percent) in Limpopo Province with the exception of Vhembe (44 percent). Cows with body condition score of ≤ 2.5 (60 percent) had a significantly higher (P < 0.05) calving rate than those with a body condition score of 3 (43 percent). Cows in Mpumalanga had more chances to calve than those in Limpopo and KwaZulu-Natal with odds ratio of 0.076 and 0.537, respectively. Additionally, quantitative data was collected through in-depth interviews using a semi-structured questionnaire. Data collected was managed and coded into themes using the Nvivo Version 11 software programme. Themes and issues that emerged were analysed and interpreted using critical social thinking and systems thinking. The results of the study revealed many factors that could compromise the implementation and adoption of ARTs in the study areas. The general feeling amongst cattle farmers interviewed was that government should address these challenges. A shortage of bulls was the main cause of the low cattle reproduction rate. The Nguni breed type cattle was perceived as the ideal cattle breed for rural areas by respondents. Oestrous synchronisation and artificial insemination can be applied under communal and emerging farming systems with success. From the study results, breeding with small framed animals such as the Nguni type breed under communal and emerging farming systems makes a lot of sense because the breed is known for its low feed maintenance requirement. Furthermore, cattle stakeholders should co-operate and work together to address many of the constraints facing cattle productivity and the implementation and adoption of ARTs in rural areas.]]> Wed 12 May 2021 23:37:40 SAST ]]> Effect of stage of lactation on milk yield, somatic cell counts, mineral and fatty acid profiles in pasture-based Friesian, Jersey and Friesian × Jersey cows https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11819 Wed 12 May 2021 23:33:58 SAST ]]> Incidence of Staphylococcus species in bovine milk: their antimicrobial sensitivity in selected antibiotics and Usnea barbata lichen extracts https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11829 Wed 12 May 2021 23:17:28 SAST ]]> Some performance characteristics of wooled sheep in the sweet and sourveld communal rangelands of Eastern Cape Province, South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11825 Wed 12 May 2021 22:29:05 SAST ]]> Time budgets, avoidance distance scores-related behaviour and milk yield of pasture-based Jersey, Friesland and cross bred cows https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11817 Wed 12 May 2021 21:01:56 SAST ]]> Effects of feeding Moringa Oleifera leaf meal as an additive on growth performance of chicken, physico-chemical shelf-life indicators, fatty acid profiles and lipid oxidation of broiler meat https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11822 0.05) on PUFA, SFA, and n-6/n-3 ratio. Treatment 1 had a highest amount of malondialdehyde (MDA), treatment 4 had no effect (P>0.05) on MDA . Storage time had an effect (P<0.05) on MDA levels, except for on Day1 and Day7. Day2 had the highest amount of MDA (0.7±0.08). The use of MOLM as an additive in broiler diets reduced lipid oxidation in meat, and maintained the quality of the broiler meat during storage. It also did not have any adverse effects on the growth performance of broilers. Therefore, it has the potential to be used as an additive in broiler diets.]]> Wed 12 May 2021 20:59:33 SAST ]]> Effects of pre-slaughter handling on pork quality from a smallholder abbatoir https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11174 Wed 12 May 2021 20:14:21 SAST ]]> Effects of pre-slaughter sheep handling and animal-related factors on creatine kinase levels and physico-chemical attributes of mutton https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11810 Wed 12 May 2021 20:07:51 SAST ]]> Farmers` perceptions of livestock feeding and rangeland management: dynamics of soil, forage and cattle blood serum mineral levels in two communal areas of the Eastern Cape, South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11581 Wed 12 May 2021 19:14:03 SAST ]]> Factors influencing the hygienic quality of milk yield from smallholder dairy herds in the Eastern Cape Province, South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:35761 Wed 12 May 2021 19:09:29 SAST ]]> Consumer perceptions and values on beef quality: implications on beef markets https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11224 Wed 12 May 2021 18:40:00 SAST ]]> Manure production and nutrient management in pasture-based dairy production systems https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11812 Wed 12 May 2021 17:34:28 SAST ]]> Effects of Acacia karroo supplementation on the quality of meat from Xhosa lopeared goats https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11808 Wed 12 May 2021 17:26:35 SAST ]]> Time budgets, blood urea content, total protein and body condition scores as adaptive responses to seasonal dynamics by breeding Nguni cows and heifers reared on a sweetveld https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11826 Wed 12 May 2021 16:33:31 SAST ]]> Perceptions of rural consumers and the quality of mutton at purchase points in the Eastern Cape Province, South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11823 Wed 12 May 2021 15:59:03 SAST ]]> Effect of agricultural extension services on beneficiaries of the Nguni cattle project: the case of Ncera and Kwezana villages, Eastern Cape Province https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11219 Tue 07 May 2024 11:38:24 SAST ]]> Effects of pre-slaughter stress, sex and breed on blood stress indicators, heat shock proteins, glycolytic potential and lamb quality https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40402 Tue 07 May 2024 10:54:04 SAST ]]> Application of assisted reproduction technologies on the indigenous Nguni cows and heifers https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11828 Thu 13 May 2021 07:17:32 SAST ]]> Effects of different grazing system on forage production and seasonal parasite loads in beef cattle https://commons.ufh.ac.za/vital/access/manager/Repository/vital:34314 Thu 13 May 2021 07:12:00 SAST ]]> Effects of dietary supplementation on physico-chemical and consumer sensory characteristics of chevon from South African indigenous goat genotypes https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11809 Thu 13 May 2021 06:30:11 SAST ]]> Avoidance-related behaviour, bleeding times and the quality of meat from sheep slaughtered at a commercial and a municipal abattoir https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11818 12months) and breeds were used. From the commercial abattoir, 90 castrates and 110 ewes were used, while 66 castrates and 19 ewes were obtained from the municipal abattoir. Meat samples were obtained to determine meat colour, ultimate pH, temperature, cooking loss and tenderness. Correlations between bleeding times and meat quality variables were also determined. The two abattoirs differed in terms of technology and the procedures used, and this brought about different response behaviours in sheep at slaughter, bleeding times at exsanguination and the quality of meat produced. Animal-related factors (breed, gender and age classes) had no effect on the avoidance-related behaviour of sheep slaughtered at the commercial abattoir, while these factors affected those sheep slaughtered at the municipal abattoir. These factors also had an effect on the quality of meat produced at both abattoirs. Gender and weight of the animals had effects on the bleeding times at exsanguination at both abattoirs. Bleeding times did no correlate with any of the meat quality variables, but correlations among meat quality variables were observed. Avoidance-related behaviour, bleeding times, and the quality of mutton from sheep slaughtered at a commercial and a municipal abattoir was affected by breed, age, and gender.]]> Thu 13 May 2021 04:49:31 SAST ]]> Perceptions of rural consumers on behaviour and beef quality of cattle slaughtered for traditional ceremonies in the Eastern Cape of South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11833 Thu 13 May 2021 04:40:31 SAST ]]> Effect of dietary inclusion of Moringa oleifera Lam leaf meal on feed conversion efficiency, meat quality, fatty acid composition, shelf life and consumer health-related perceptions of pork https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11827 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.]]> Thu 13 May 2021 04:03:48 SAST ]]> Effects of dietary inclusion of Moringa oleifera leaf meal on growth performance, physico-chemical attributes, oxidative stability and sensory quality of pork https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11836 0.05) on the physico-chemical quality of pork from LW pigs; although it significantly (P<0.05) increased a* and reduced WBSF values in pork from KB pigs. Pork from LW pigs receiving 5% MOLM had significantly increased (P<0.05) n-3 content of the subcutaneous tissue of LW pigs compared to KB, and also when compread to other treatment groups. In both breeds, the composition of PUFA: SFA and n-6: n-3 in the subcutaneous adipose tissue was significantly (P<0.05) lower in T2 and T3 than in T1. The n-3 levels for pork muscle from LW pigs receiving 2.5% and 5% MOLM, and from KB pigs receiving 5% MOLM, were significantly (P<0.05) lower. Inclusions of MOLM significantly (P<0.05) reduced the n-6: n-3 fatty acids in pork from both LW pigs and KB pigs. Consumer scores on sensory attributes (aroma intensity, initial impression of juiciness, first bite, sustained impression of juiciness, muscle fibre and overall tenderness and overall flavor intensity) significantly (P<0.05) increased as the level of MOLM inclusion in the diet increased; and higher scores were observed in fried meat than in boiled for most sensory attributes. It may be concluded that inclusion of MOLM in pig diets up to 5% improved the ADFI, a*, tenderness of pork without adversely affecting the FCR and other physico-chemical quality attributes; and resulted in desired increase in levels of n-3 and reduced the n-6: n-3 fatty acid ratio.]]> Thu 13 May 2021 03:31:39 SAST ]]> Effect of full and semi-scavenging rearing systems on crop contents and the quality of meat from village chickens during spring season of Eastern Cape, South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11807 Thu 13 May 2021 03:26:22 SAST ]]> Antioxidant activity and the quality of meat from goats and broilers supplemented with Moringa (Moringa Oleifera) leaves https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11803 Thu 13 May 2021 03:25:11 SAST ]]> Perceptions on ante-mortem welfare, quantitation of pain and pregnancy biomarkers, muscular fibre architecture and quality of Dohne Merino offal https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11824 Thu 13 May 2021 03:17:47 SAST ]]> Effect of post-slaughter handling on physico-chemical and microbiological quality of red meat along the distribution chain in the Eastern Cape Province, South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:27875 Thu 13 May 2021 03:09:14 SAST ]]> Effects of production systems and canola meal supplementation on carcass and meat quality characteristics of spent laying hens https://commons.ufh.ac.za/vital/access/manager/Repository/vital:34309 Thu 13 May 2021 02:00:02 SAST ]]> The effect of moringa oleifera leaf meal on growth perfomance, gut integrity, bone strenght, quality and oxidative stability of meat from broiler chickens https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11820 0.05) on the weights of the heart, liver, spleen, or the gizzard, although the bursa for T2 birds was the lightest (P < 0.05); while gizzard erosion score was highest in T2 birds.
