The growth and development of replacement gilts of different precocity and age depending on the terms of transition from herd-producer to the market area of a complex was studied in the conditions of the Republic of Belarus. Animal transfer into new housing conditions affected the early maturing and super early maturing breed pigs of experimental groups. It was determined that moving of replacement pigs into the market area of the complex at the age of 115 days made it possible to obtain higher indices of swine productivity. Fertilization rate of sows of the first experimental group after the first insemination made up 77,6%, that was higher on 6,2% and 9,5% in comparison with the control and the second experimental groups, respectively. The advantage of the first and second experimental groups over the control one was stated in a higher multiple fetation on 0,4 heads and heightened heavy litter indices on 0,1 kg; the quantity of weanling was higher on 0,6 and 0,5 heads, on litter weight at weaning was higher on 7,1 and 3,8 kg, respectively
