In the article, the efficiency of two-phase rearing of piglets was compared with a change in the feeding system from dry to liquid feeding for different periods of the phases of this production cycle. It was discovered that animals reared in a one-phase system with dry feed had the lowest daily feed intake on average. In contrast, those in a two-phase system, with the second phase involving liquid feed for 9 days, showed a 14.8% increase in average daily consumption. This figure rose to 20.3% with an 18-day duration of the liquid feeding phase and further to 32.4% with a 27-day duration, compared to animals in the single-phase system. It was found that when the piglets were fed liquid feed for 18%, 35% and 53% of the total rearing period in the second rearing phase, their live weight increased by 3.4%, 7.9% and 12.2%, respectively, at the transition to fattening with analogues with single-phase top-up and 100% dry power supply system. The highest income was achieved in animals reared in two phases with a phase duration of 27 days on liquid feed, which was 6.2 % higher than in animals reared in one phase on dry feed, and 16.0 % higher in two-phase rearing with a second phase duration of 9 days and 7.3% higher than in two-phase rearing with a second phase duration of 18 days.
