Milk productivity of mares

To determine the milk productivity of Kazakh horses of the Adai region in variants of selection and technological indicators of milk for the production of cumus in the conditions of the Mangyshlak peninsula of the Republic of Kazakhstan. The object of the study was the Kazakh horse of the Adai intra-breed type at "Taushyk" LLP (Tupkaragan District, Mangystau Region). Mares with a more pronounced milk production were selected and analyzed . they have investigated the quality of milk for further processing. A characteristic feature of the dynamics of milk sugar content during lactation has been identified. The highest lactose concentration was observed in the 4th month of lactation, followed by a decline. In the first two months of lactation, no significant changes in lactose content were detected. The milk produced by mares of the Kazakh Aday breed is characterized by a high content of fat and lactose and therefore meets the technological requirements for koumiss production. According to the research results, it was found that the homogeneous selection of parental pairs cup-shaped + cup-shaped ensures the yield of offspring of daughters cup-shaped 70% and rounded 30%. With the improving heterogeneous selection of rounded + cup-shaped, the yield of mares with cup-shaped udders was 60% and rounded 40%.
