Description/Abstract

This study aimed to investigate the effect of age at weaning of calves on non‐ esterified fatty acids (NEFA) and reproductive parameters of beef cows. Animals (n = 65) were randomly assigned to three treatments after calving: hyper‐early weaning (W30) at 32 ± 0.89 days, early weaning (W75) at 77 ± 0.95 days, and conventional weaning (W180) at 183 ± 0.82 days. Body weight (BW) and body condition score (BCS) were evaluated at parturition (AP) and at 30, 45, 64, 81, 100 and 115 days postpartum (dPP). Blood samples were collected to analyze NEFA levels and progesterone (P4) at 30, 45, 64 and 81 dPP. Higher BW and BCS were observed from 64 to 115 dPP in W30 cows than W180 ones (p < 0.05). Cows subjected to W30 condition had higher levels of NEFA at 30 dPP compared to 64 and 81 dPP (p < 0.05). We also observed that cows from W180 group showed decreased levels of NEFA at 30 dPP compared to 45 (p < 0.01) and 64 dPP (p < 0.05). The highest P4 level was observed at 64 dPP in W30 cows compared to W75 and W180 (p < 0.05). We also observed higher CR of W30 (86%) compared to W180 (47%) at 45 dPP (p < 0.05). The overall pregnancy rate (PR) was higher for W30 (95.5%) than W180 (73.9%). In addition, higher BW at calving and P4 levels at 30 dPP were positively correlated with the possibility of pregnancy (p < 0.05). Improvement in BW and BCS were observed in cows subjected to hyper‐early weaning management. However, levels of NEFA decreased as the postpartum period progressed. We concluded that cows who weaned calves hyper‐early have greater chances of increasing cyclicity and PRs.

Description/Abstract

Climate change is now known to be a key threat to achieving sustainable development and poverty reduction targets, as well as attaining the Millennium Development Goals (MDGs), in Africa. Climate change is altering rainfall patterns, water availability, and sea levels; it is increasing droughts and the frequency of bushfires, and increasingly impacting on human health, agricultural productivity, forests and biodiversity. In this way, climate change will negatively affect the social, economic and environmental dimensions of human livelihoods in Africa.

Description/Abstract

Lesotho Agricultural College [LAC] is committed to providing professional education and training, promoting research and community outreach, providing guidance on commercialized agriculture, through combining quality theory, practicals and research methodologies. The College strives to remain relevant, forward-thinking, industry-related in developing graduates who are thinkers and practitioners. The College programmes involve practicals and theoretical knowledge facilitated by highly skilled academic professionals by ensuring that students are well equipped to enter the world-of-work confidently upon graduation.

With this intent, through the Department of Crops [CPD], LAC is engaged in collaborative partnerships with other Government ministries and Departments, NGOs, and commercial farmers to create a platform for internship. Through this initiative, the CPD placed the first group of students of Diploma in Agriculture (General) and Diploma in Agriculture (Crop production) for an internship at the Department of Agricultural Research [DAR] and to thirty-two (32) farmers who are actively engaged in horticulture enterprises in Lesotho. These enterprises and farms were selected based on their accessibility to the students. The internship ran from the 27th June 2022 to 22nd July 2022.
