Abstract
The results of the dependence of the milk productivity of cows on the use in the rations of sunflower and rapeseed meals are given. An introduction to the composition of diets for feeding cows of a dairy herd of sunflower and rapeseed meals has been proposed, which makes it possible to increase the protein content and improve the nutritional value of the rations. The use of rapeseed meal leads to an increase in p oorly soluble protein, which positively affects the performance of milk production of cows. The use of sunflower and rapeseed meals in the amount of 0.5 kg provides an increase in the milk yield of basic (3.4%) fat content by 13.3% and 17.1%, respectively, compared to the control. Inclusion in the rations of cows feeding dairy herd of rapeseed meal containing more, compared to sunflower meal, the amount of protein protected from splitting in the rumen, contributes to an increase in milk yield and fat content in milk of cows.
