The research aims to study the reproductive indicators and dairy productivity of the modern Kazakhstan population of the Alatau cattle breed. The average duration of the dry period is within the physiological norm, being 60-75 days. As noted above, an increase in the service period can negatively affect herd reproduction. In this regard, some measures were taken to normalize the service period of 83.5, 79.6-83.5 days. The efficiency of the insemination of cows is 92-95%. In comparison with 2018, in 2019, milk productivity increased on average by 3.64% or 197.5 kg of milk, in 2020 by 5% or 268.8 kg of milk, in 2021-by 13.6% or by 736.7 kg of milk, but in 2022 there was a sharp decrease of 28% or 972.6 kg of milk Alatau cows during the first lactation produce milk in the amount of 5262.3±39.7 kg, with a fat content of 3.90% and a milk protein content of 3.25%. In the second lactation, the milk yield increases to 5788.9±51.0 kg, and in the third lactation to 5786.7±33.8 kg.
