Milk Content and Milk Quality of Sheep of the Kazakh Fat-Tailed Semi-Rough-Haired Breed with Pasture Content

Abstract

The article presents the results of a study onthe effect of top dressing and feed additives based on humic substances on milkproductivity, the quality of milk of sheep of the Kazakh fat-tailed semi-coarsebreed, and the resulting cheese in pasture conditions. In total, 90 heads ofsheep of the Kazakh short-tailed semi-rough-haired breed were used in theexperiment. The Control Group (CG) of 30 sheep grazed on pasture grass, whiletwo 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 humicsubstances. As a result, after the first month of feeding, additional feeding had a positive effect on thedaily milk yield of ewes, where the experimental group II was statisticallysignificantly superior (P<0.05), i.e., it exceeded by 0.08 liters. In total,during lactation, the sheep of the second experimental group exceeded thecontrol group by an average of 10.8% in average daily milk yield. Also,additional feeding affected the quality of milk and cheese, Thus, theindicators of sheep of the II experimental group were superior in terms of thefat content of milk (P<0.01) and cheese (P<0.05).
