The trial was carried out in the Institute of Forage Crops, Pleven in 2011. The objective was to establish the effect of substitution of 40% of the protein of soybean oil meal in the compound feed for dairy sheep by protein from brewers grains on the sheep milk amount and composition. Twenty-two dairy sheep of the Pleven Blackface sheep breed were used 35 days after lambing, divided into two groups according to milk yield, lactation number, live weight, body state and days after lambing. The sheep were fed with maize silage, lucerne hay and compound feed composed of maize, wheat, soybean oil meal in the one group, and in the other group 40% of the protein of soybean oil meal was substituted by protein from brewers grains - 0,450 kg DM/head. The content of feed units for milk was the same in the two rations, 1,10 FUM/kg DM. No significant differences were found in the milk amount at milking between the two groups. The obtained milk from the sheep for the experimental period of 161 days, including 77 days of feeding in confinement and 84 days of pasture feeding was 139,8 l and 138,8 l per head for feeding with rations with participation of soybean oil meal and for substitution of 40% of the protein of soybean oil meal by protein from brewers grains, respectively.
