The article presents the materials of studying the milk productivity of local and imported sheep breeds and their crossbreeds. Udder and nipple measurements were taken from the studied sheep, and udder volumes were calculated on the basis of the measurement data. By the method of control yield, milk production has been studied during the suckling, milking period and lactation. The highest milk yield for a total lactation of 365.66 liters was obtained from Ostfrizian ewes and on second place the Assaf breed with a productivity of 355.52 liters, from the crossbred ewes ♀ Tsigay x ♂ Ostfrizian for lactation was obtained 290.15 liters of milk, and from ♀ Karakul x ♂ Awassi 326.30 liters with a reliable difference of P ≤ 0.001 to the average data for the groups. The chemical composition of milk at Karakul sheep is significantly higher (P ≤ 0.001), compared to the average for the studied breeds, and at Ostfrizian sheep and their crossbreeds with Tsigay ♀ Tsigay x ♂ Ostfrizian, the percentage of fat is lower, the other indicators are also significantly higher.
