Breeding-Genetic Parameters of Productiveness Traits of Belarusian Meat Breed Sows at Crossing with Landrace Breed Boars

Abstract

As a result of researches it was determined that Landrace Breed Boars influence positively at reproductive traits of Belarusian Meat Breed sows, but individual influence of boars of separate lines was not equal. The mean square deviation and variation ratio at Belarusian Meat Breed sows’ reproductive traits during crossing with Landrace Boars was higher than that of purebred sows. It shows the presence of significant resources for further productiveness growth. It is determined that selection of sows on multiple pregnancy factor decreases live weight of piglets, and so the sped of their further growth. The average live weight of a weanling is in straight dependence on macro-farrowing. Selection on macro-farrowing and live weight factor of a sucking piglet will influence the speed of growth.
