Abstract
This article presents the results of milk productivity of the first lactation for 305 days of the Kazakhstan three-pedigree milk direction of Simtals cows of the Ertis type and their crosses (Ertis x red-motley holstein and Ertis x Simmental) bred in the conditions of the peasant farm Kamyshinsky of Shemonaikhinsky district of East Kazakhstan region. As a result of the study, comparisons were made of the volume of milk baked, as well as the percentage of fat and protein in the composition of the milk of the first lactation for 305 days of Simtal Ertis cows taken under control with the results of their crosses for the first lactation. Based on the materials presented, the volumes of milk of control milking in each month of lactation were compared; on the basis of these indicators, a lactation curve was shown for the first lactation of Simmental cows of the Ertis type and their crossbreeds.
