MAQOLA ANNOTATSIYASI

The study investigated the milk productivity of Holstein cows imported from abroad under the conditions of Uzbekistan. During the research, it was found that the cows in Group II achieved the highest milk productivity during lactation. The milk yield of this group was higher by 499.0 kg (10.0%) and 881.5 kg (19.2%) compared to their counterparts in Groups I and III, respectively. The milk fat yield was higher by 18.2 kg (9.45%) and 32.5 kg (18.24%), the 4% milk yield was higher by 460.3 kg (9.57%) and 813.8 kg (18.27%), and the milk productivity coeffi cient was higher by 99.7 kg (9.745%) and 174.5 kg (18.39%) compared to Groups I and III, respectively.
