The influence of feeding conditions of suckling piglets on their growth in the subsequent periods of cultivation is investigated in the article. The aim of the scientific and economic experiment was to establish the effect of suckling piglets on increasing the productivity of lactating sows and growth, development, feed consumption and etiology and foraging activity of piglets both in the suckling period and after weaning from sows. For this purpose, 4 groups of sows with three heads in each were formed on the principle of analogues. Five days after farrowing, 10 piglets were left in each nest during weaning. This took into account their live weight at birth and at 5 days of age. The sows of the control group fed 10 piglets, while the sows of the 2nd, 3rd and 4th groups fed 20, 30 and 40 piglets, respectively. After the piglets reached 5 days of age, the suckling regime, except for the animals of the control group, was artificially regulated. To do this, sows were expelled for the time provided by the scheme of the experiment on the playground, where they received according to the norms of feeding standard feed. The suckling piglets received cow's milk and weaning from a place where they were fed, and had free access to feed according to age. As a result of research, it was found that reducing the number of suckling pigs per day to 8-24 times compared to raising piglets with free access to the uterus leads to more eating of feed in suckling and subsequent periods of pig breeding. At the same time, in young pigs, which previously adapted to the consumption of feed during the weaning period and had a regulated weaning, there is an increase in live weight, average daily gain, weight and volume of the stomach and increase their productivity. It is proved that the conditions of the regulated subsystem significantly affect the multiplicity and duration of consumption of breast milk by piglets
