Abstract

The Holstein breed of dairy cattle is the most widespread due to its high productivity (7000–11000 kg of milk with 3.6–3.8 % of fat and 3.0–3.2 % of protein), good adaptability to a variety of climatic, feed and technological conditions, as well as a high feed conversion ratio. In this regard, the breeding of animals of this breed, including the pedigree breeding and the creation of optimal conditions for directional rearing of young animals, is of great importance for the economy of the Republic of Belarus. Any breed is characterized by a distinctive quality, a certain structure, and specific morphological and economically useful traits. The goal of our work was to analyze the main economically useful traits of two new factory lines Bukem 66636657 and Blitz 17013604 of the Holstein breed of dairy cattle of domestic selection. To achieve this goal, we used the UE “GIVC Minselhozproda” information database of pedigree dairy cattle bred at basic farms. It has been established that cows of new factory lines are characterized by high milk productivity rates, good reproductive performance and sufficient development regardless of breed line. The effective use of animals of new factory lines will increase the genetic potential of milk productivity of herds, allowing for obtaining high-value young pedigree cattle of domestic origin.
