BEHAVIORAL ACTIVITY OF COWS OF THE HOLSTEIN AND KHOLMOGORY BREED IN THE CONDITIONS OF ROBOTIC MILKING
The article is devoted to the study of the behavioral activity of firstcalf cows of the Holstein and Kholmogory breeds in the conditions of robotic milking. Holstein cows spend 13.4% more time in the standing position. They also spend more time on feed consumption - 385.6 minutes against 312.5. The process of chewing the cud lasts 33.4% longer in cows of the Kholmogory breed. The indices of food, motor and total activity were calculated. The index of food activity was 0.539 in the Holstein heifers, 0.579 in the Kholmogory heifers, the index of motor activity was 0.541 and 0.477, respectively. In terms of the index of total activity, the animals do not differ - 0.74. The milk productivity of cows of both breeds is positively associated with the duration of feeding (r = 0.35 and 0.26), lying (r = 0.44 and 0.52) and the chewing the cud (r = 0.66 and 0.34). Milk productivity in cows of the Holstein and Kholmogory breeds has the maximum relationship with the index of food activity (r = 0.61 and 0.47).
