Comparative assessment of the productivity of pigs of different breed combinations

The urgent task of pig breeding is to improve the genetic structure of types and lines of pigs, as well as to create hybrid forms that are most effective under intensive technologies. This article presents studies of the offspring born by crossing pigs of a large white breed, the Duroc / Pietrain breed with an F1 parent pig. The experimental part of the work was carried out in the conditions of Znamensky SGC LLC. The object of the study were piglets born from the following paternal and maternal lines: large white X large white (control group), Duroc X F1 Libra (1st experimental group), Pietrain X F1 Libra (2nd experimental group). Each group consisted of 30 animals, the formation was carried out according to the method of pairs-analogues. The subject of the study was productivity of animals of the studied groups. The results demonstrate that when studying the growth rates of piglets at weaning, a significant difference was obtained in experimental groups 1 and 2 by 7.4% (p
