In total, 90 heads of sheep of the Kazakh short-tailed semi-rough-haired breed were used in the experiment. The Control Group (CG) of 30 sheep grazed on pasture grass, while two Experimental Groups (EG) of 60 heads were fed 300 g barley per day of barley, The second experimental group of sheep received a feed additive based on humic substances. As a result, after the first month of feeding, additional feeding had a positive effect on the daily milk yield of ewes, where the experimental group II was statistically significantly superior (P<0.05), i.e., it exceeded by 0.08 liters. In total, during lactation, the sheep of the second experimental group exceeded the control group by an average of 10.8 in average daily milk yield. Also, additional feeding affected the quality of milk and cheese, Thus, the indicators of sheep of the II experimental group were superior in terms of the fat content of milk (P<0.01) and cheese (P<0.05).
