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 ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40402 Tue 07 May 2024 10:54:04 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11824 Thu 13 May 2021 03:17:47 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:27875 Thu 13 May 2021 03:09:14 SAST ]]> 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. All of the nutrients measured, except for fat, had negative intercepts that were significantly different (P < 0.05) from zero, indicating the presence of endogenous fecal losses. Tibiae length (TL) was highest in T2. The dried defatted weight (DW) was heaviest (P < 0.05) for T3 (11.20 ± 0.347) and T5 (11.08 ± 0.328). A positive correlation (r = 0.667; P < 0.01) between TW and DW was observed. There were no dietary effects on bone breaking strength (BBS), but T1 tibiae had highest resistance to breaking force (T1 > T4 > T3 > T2 > T5). Calcium was highest (P < 0.05) in T1; and lowest inT2 and T5. Phosphorus levels were lowest (P < 0.05) in T1; and highest (P < 0.05) in T5 compared. The highest Ca: P ratio was obtained in T4 (P < 0.05); while the ash percent was highest (P < 0.05) in T1. Drip loss increased as L* values increased; and a negative correlation was observed between L* and pH. On D1, C18: 0 and C22 in T2, while C15:0 was highest in T4. On D1, C20:2, C20:3n6 and C22:6n3 were highest in T2 (P < 0.05); T4 had the highest C18:3n6 (P < 0.05), while C20:2 was highest in T5 (P < 0.05). The P/S ratio on D1 was highest in T4; while n-6/n-3 was highest in T1; and n-3 was highest in T3. On D8, the n-3 was highest in T1 (P < 0.05). Results of the current study show that supplementation of M. oleifera leaf at additive levels of up to 5 percent of the bird’s DMI does have the potential to influence the bird performance without any detrimental effects on nutrient utilization, bird health, bone strength and/or meat quality, which can be concluded that MOLM enhanced the bird’s genetic potential for optimal productivity.]]> Thu 13 May 2021 01:45:03 SAST ]]>
