Description
Summary:Our work provided for the study of the impact of directed reproduction of cows on the formation of highly productive healthy herds in the basic farms of the Republic of Kazakhstan. For accelerated replacement of herd and increase of number of highly productive cows in large farms for milk production one uses sexed semen at the first and the second insemination of primiparous cows obtained from highly productive mothers. The efficiency obtained from using this technique is 65-95% of individuals of the desired sex. Insemination was carried out by recto-cervical method using a tool AlphaVision frozen-thawed sexed semen divided by sex. The highest results of the fruitfulness of insemination with sexed semen in Agricultural production cooperative “Breeding Plant Almaty”, Individual entrepreneur “Karimov” and Kakpatas Kordai were obtained in the autumn-winter period and ranged from 58.1 to 65.2%, with an insemination index of 1.58-1.72. Economic efficiency when using the technology of artificial insemination of calves with sexed semen amounted to 10,040.2 tenge. When using sexed semen, an average of 92% of calves were obtained from bovine. Less insemination costs, the profit from calf production amounted to 76,109.2 tenge.
