MILK PRODUCTIVITY OF TUVAN SHEEP AT DIFFERENT AGES
It is known that such factors as the survival of lambs, their development and the formation of subsequent productivity, are primarily ensured by the milkiness of the ewes. Even nowadays, during selection it has not been paid enough attention to the milk production of sheep, although the milk production of ewes is extremely important for the development of lambs. The article presents the results of a study of the milk productivity of Tuva ewes of different ages. The milk yield of the ewes was studied for the first 20 days of lactation, the average daily and one-time milk yields were determined, the chemical composition of the milk of the ewes was analyzed, the characteristics of the experimental sheep by age, live weight, and udder measurements were given. The article first describes the development of the udder of Tuvan ewes in connection with age. The results of the study revealed the age-related characteristics of the milk production of Tuvan breed of sheep.
