Abstract

The milk yield of Bushuev cattle bred in the extremely hot climate of Syrdarya region was 2742 kg in the first lactation, 3412 kg in the second lactation, and 3597 kg in the third lactation. According to the herd with high milk productivity in 4-6 months, in the III-lactation, 700 kg more milk was milked from dairy cattle than in the I and II-lactation. It was observed that the coefficient of milk production of cattle increases with the increase of lactation periods. The difference between them was 100-200 kg. The results of the analysis showed that the highest live weight was observed in the III-lactation group of cattle and was 468 kg. According to the results of the inspection carried out on the farm, the fat content of the milk of the cattle in the herd was 3.9-4.1%. The average fat content of milk was 113.4 -164.7 kg. Feed consumption of 1 liter of milk obtained from Bushuev dairy cattle was equal to 1.15 feed units. The average amount of milk milked from one head of cattle in the farm was 3572 kg. The unit of feed consumed during lactation was 4107 kg.
