Abstract
The purpose of the research was a comparative assessment of the growth dynamics of Kalmyk bull calves from birth to 15 months of age in breeding farms of the Republic of Kalmykia. The phenotypic parameters of animals in 18 breeding farms of the republic engaged in breeding purebred Kalmyk cattle were evaluated. At the age of 15 months, Calmyk bulls had an average live weight of 380 kg, the highest value in the farm ―Erketeni‖, SEC ―Hoshud‖, SEC ―Khanata‖ (393 kg), the lowest – in SEC ―Pervomaisky‖ (337.3 kg) (P <0.05). The animals with the highest live weight correspond to the elite-record class. A comparative assessment of Kalmyk bull calves by live weight allows us to draw a general conclusion that bull calves grow and develop in accordance with general patterns.
