Increase of breeding capacity of sows of Wales breed

Abstract

The purpose. To estimate the level of breeding capacity of sows of Wales breed in comparison with other breeds and its place in swine breeding according to basic localization in view of preliminary work on increase of genetic potential of productivity by complex of attributes. Methods. Results are given of selection-breeding work in swine breeding of Kharkov oblast. Genetic potential and degree of its realization is calculated. Results. Outcomes of work on increase of the level of genetic potential of productivity of sows of Wales breed are brought. Analysis of modern state of breed is carried out. Place of the breed in swine breeding on its basic localization is specified. The part of the breed in pedigree facilities of Kharkov oblast makes 62,5% of general livestock. The level of breeding capacity of sows is estimated and values of SIVJS index are calculated. Conclusions. Use in selection process of the developed methods of selection has provided increase of the level of breeding capacity of sows of domestic population of Wales breed. That in the further will reflect in status of the breed on its basic localization in Ukraine.
