INFLUENCE OF METHODS OF BREEDING ON THE REPRODUCTIVE QUALITY OF SOWS
The article presents the results of studies on the influence of breeding methods on the reproductive quality of sows. It was found that high fertility was observed when crossing the Queens of large white breed with boars of white short-eared breed of 10.2 piglets. The highest milk content-171,0 kg, obtained from purebred sows, crossed with boars breed Duroc. The best productive indicators of sows-primroses were noted at simple three-breed industrial crossing of sows of large white breed with boars of white short-eared breed and breed of Duroc, and also at return crossing of sows (KB x BK) with boars of white short-eared breed.
