The influence of the age of the first insemination of pigs on their subsequent productivity was evaluated. In the period from 2017 to 2020, 167 pigs were inseminated in the company Plemzavod-Yubileyny in the Tyumen region, which were divided into groups. Productivity indicators were analyzed based on the number of piglets born. In 2017, 12.5 piglets were obtained in group III, where the age of the first insemination was 241-253 days, and 12.7 piglets were obtained in group VI (281-311 days). In 2018, 101 sows were farrowed out of 164 heads (groups I, II, III), 1123 piglets were received from them, 1037 live ones were received. The largest number of piglets born was observed in group IV-12.4 units. In 2019, the largest number of piglets born was observed in group III-11.4 units. In 2020, out of 181 farrowings, 135 units were received, of which 1,528 piglets, of which 1,507.5 live.
