Introduction to the diets of sheep-producers of wool (Jalgin merino) and meat-wool directions (Russian meat merino) productivity in the non-breeding and breeding period of the feed additive «corn Gluten» in the amount of 28 and 56 and 28 and 66 g per unit per day contributes to an increase in crude and digestible protein by 5,0 and 10,0 %, lysine by 1,52 and 3,0 %, methionine with cystine – by 5,2 and 12,7 %. In addition, the digestibility of dry matter of the diet (in the non-breeding period) is significantly increased by 3,85-6,74%, by 13,4-15,11% – raw protein, by 3,19-5,03% – raw fat, by 5,92-7,21% – raw fiber, as well as nitrogen-free extractive fraction – by 1,90-3,52%. Feed additive «corn Gluten» promotes a significant increase in the volume of ejaculate in breeding period by 2,45,7% and 2,8-7,0%, sperm activity and an indicator of resistance to 0,3-0,6 and 0,5-0,6 points and 450-800 units, sperm concentration – by 1,7-3,0 and 1,7-3,5 %, ewes’ fertility – by 3,0-5,0 and 2,0-3,0 %. The additional income from the sale of sperm products with an increase in the protein level in the diets of sheep-producers Jalgin merino and Russian meat merino by 5% is 3,63-4,32, and by 10 % – 8,20-10,26 thousand rubles.
