The purpose of research is improving the efficiency of use of feed concentrates for lactating cows newly calved by use in their feed the rapeseed meal and camelina meal. The feasibility of using protein components obtained from the seeds of cruciferous crops – canola and winter camelina has been determined in two trials for Hoilstein cows of Black-Motley breed. In the first trial it has been found that the inclusion of 5.0-10.0% rapeseed meal in animal feed provides the 1.4-3.4% increase in protein milk yield. Introduction into the feed 10.0-15.0% of camelina meal provides the 2.8-4.2%. Increase of milk production within the animal of experimentsl groups (in terms of milk 4% fat). The best indicators of cost per 1 kg of 4% fat milk have been found to be in the 2nd and 3d experimental groups: 8.53-8,57 MJ OE; 135-137 crude protein; 343-348 g of combifeed. Replacing of sunflower meal by 15.0% Camelina sativa in the combifeed-concentrate has raised nutrient digestibility of feed ration compounds. Profitability level of milk production has been 7.5 abs.% higher than the control.
