Abstract

The study of the effect of protected carbamide in sheep nutrition is an urgent area of research in the field of animal husbandry. The article presents the materials of a scientific experiment aimed at developing norms for feeding “protected” urea as part of compound feeds for sheep of the meat and wool production line during lactation. Studies have established that the inclusion of compound feeds enriched with “protected” carbamide in the diets of lactating sheep contributed to an increase in economically useful signs and had a positive effect on the qualitative and quantitative indicators of milk. It was revealed that the amount of fat in the milk of animals of the experimental groups increased by 0.04 and 0.14 abs.%, protein – 0.02 and 0.05 abs.%, lactose – 0.04 and 0.11 abs.%. The caloric content of 100 g of milk increased by 0.65 and 1.91 Kcal, respectively.

Intensive growth of lambs was recorded during the suckling period, due to high indicators of milk productivity and milk quality in sheep of experimental groups.
