Effects of Vitanimal-based supplementation on dairy and economic performances of Borgu cows in Benin

Abstract

The main objective was to evaluate the impact of a feed supplement, Vitanimal (a mixture of husks and cotton cake), on the dairy performance of Borgu cows in a context of scarcity of fodder in the dry season and reduced pastoral mobility. The evaluation concerned a herd of 15 cows that had had at least two calvings at the Okpara Breeding Farm. The animals were divided into three groups: group 1, the control group, received only fodder from the farm’s natural and artificial pastures, salt blocks and water ad libitum; groups 2 and 3 received the same feed as the control with the addition of 2 and 4 kg of feed supplement, respectively. The quantities of milk produced and supplement refused were collected and quantified daily for 90 days. Analyses showed significant differences (p < 0.05) in the supplement intake between groups 2 and 3, and in the refusals (p < 0.05) which were greater in group 3. Vitanimal had significant effects on the cows’ performance. Daily milk production was 0.76 ± 0.35 kg, 1.04 ± 0.35 kg and 1.16 ± 0.46 kg in groups 1, 2 and 3, respectively. These quantities increased with the amount of supplement served. However, the group 2 diet was more profitable, with a 75% profitability rate compared to 25% in group 3.
