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.
