As a result of the researches unequal effect of boars of Yorkshire, Duroc and Landrace breeds of Canadian selection at reproductive traits of pure-breed and cross-breed of sows is determined. It is also determined that sows of Great White x Belarusian Meat and Belarusian Meat x Landrace breeds had the highest index of reproductive traits within boars of Landrace breed, when the heterosis level of multiple pregnancy compared to control group animals was 14,4 and 17,6%, on milkiness - 4,2 and 5,5%, on litter weight at weaning - 14,0 and 16% correspondingly.
