The article investigated the productivity of Danish-bred piglets during rearing in small and medium-sized pig farms and large industrial complexes, as well as the effectiveness and components of rearing costs and the influence of pig farm size on them. In small pig farms, it was found that piglet survival rate during rearing was 0.24-0.45% higher and growth intensity was 3.15-5.46% higher during this period. The absolute gains were 0.59-2.50% higher and the weight of piglets at transition to fattening was 4.53-8.50% higher than in medium and large size farms, respectively. At the same time, animals in large farms had 4.15% lower birth weight, 3.17% absolute and 2.19% average daily gains and 1.60% lower weight of animals at transition to fattening compared to medium size farms. It has been shown that the most effective feed was used by animals reared in medium capacity farms. The feed cost per piglet was lowest for animals reared on medium-sized farms, 9.67% lower than for animals reared on small farms during this period, and 9.70% lower than for animals reared on large pig farms.
