Exteriority of Holstein Cattle of Various Origins in the Conditions of the Tyumen Region

Abstract

The modern production of animal products depends largely on the quality of animals. Dairy farming is most often based on the use of Holstein cows as one of the most adapted to industrial conditions[1]. The Tyumen Oblast has been importing the cattle of this breed since 2006, and it was imported from different European countries, as well as was obtained as a result of the absorption crossbreeding of cows of the domestic black-motley breed [2–4]. Since the productivity of animals to a large extent depends not only on the origin, but also on the external qualities of animals, a study of the exteriors of the first exteriors of the Korovogolshtin breed was carried out. In the course of the study, it was found that both the origin and the ”farm” factor were influenced by the exterior quality of the animals. Moreover, the influence of the ”farm” factor was greater than the origin of cows. The cows of their own breeding, obtained as a result of absorption crossbreeding, did not differ significantly from the imported cows by the majority of external indicators. This allows us to conclude that the imports may be replaced by our own reproduction, including the use of absorption crossbreeding of black and motley and Holstein cattle.
