Abstract

The article presents the expediency of using valine in the feeding of growing quails of meat direction of productivity. The studies were conducted in the conditions of research laboratory of feed additives of National University of Life and Environmental Sciences of Ukraine. The experiment was conducted with growing Pharaoh quails. It was selected 500 daily quails. Birds were placed in 20 cages with 25 heads in each. In the formation of analog groups, the body weight of the birds was taken into account. Quails were fed full-fledged mixed fodder, which was balanced by energy and other nutrients. The feed for the quails of the control group contained the natural level of valine, and the experimental groups additionally L-valine according to the experimental scheme. Observed a relationship between the level of valine in feed and feed conversion (R2 = 0.7359). The most effective level of valine in mixed fodder for quail, which is grown for meat, to obtain a sufficiently large body weight with a low level of feed intake per unit of growth is at 121-day age 1.68% and at 2235-day age 1.23%.
