The main trend in the development of the pig-breeding branch of the Republic of Belarus is to improve the productive qualities of the breeding stock. The questions of the optimal live mass and insemination age of the female pigs are analyzed. The studies on the perfection of replacement pigs growing technology at industrial complexes are carried out. The reproductive qualities of the herd replacement pigs during the insemination, their impregnation capacity and the number of piglets got from one female are displayed. It is determined that passing gilts to the insemination section is good to carry out considering individual traits of animals' maturation. Their live weight should be not less than 115 kg. It lets us cut the growing period at 14 days (5.4%) and the quantity of gilts not in rut – at 3.4%. Early transition of pigs in the industrial area of a complex promotes better adaptation and lets us get 1.4% more farrowing without the litter size decrease. Sows of industrial herd of a complex should correspond to transitional type parameters that are able to resist unfavorable factors of industrial technology
