REPRODUCTIVE CAPACITY AND DAIRY PRODUCTIVITY OF COWS IN THE CONDITIONS OF KAMYSHENKA LLP, AKMOLIN

Abstract

The authors of the article present the results of studying the reproductive ability and milk productivity of black-and-white and Simmental cows in the conditions of Kamyshenka LLP in the Akmola region.In the structure of the herd, the specific weight of cows is 46 %, which is insufficient for dairy cattle breeding (in dairy farms, the specific weight of cows is 50-60%).Reproduction indicators, namely insemination for both breeds occurs at approximately the same age of 19.3-18.8 months.The average milk productivity of cows was at the level of 5460 kg per lactation for the herd, which showed an increase of 11% compared to the previous indicators. The fat content of milk is within 3.7% and the protein content is 3.23%. At the same time, the number of somatic cells, thousand units/ml was in the range of 282.1 thousand units/ml, which corresponds to the norm.
