As a result of realized research it was revealed that in conditions of a pork production complex 'Domanovichi' the best indicators of efficiency (multiple fetation - 10.9 heads, milking efficiency - 68.4 kg, litter weight in 2 months - 186.1 kg) were obtained at sows of large white breed at crossing with boars of the pietrain breed in comparison with thoroughbred breeding (multiple fetation - 10,3 heads, milking capacity - 61.8 kg, litter weight in 2 months-160.3 kg), and obtained the mongrel young growth possessed higher (261g) intensity of growth (on 18 g or on 7.4% more than in a control group).
