Artificial insemination of sows in modern farms producing high-quality pork is justified both economically and technologically. The studies were implemented on a herd population of 3,300 sows of the high prolificacy hybrid (YL) of Danish selection — PIC. For artificial insemination of sows was used next methods: cervical insemination (Conventional Artificial Insemination), Intrauterine Artificial Insemination. Analyzing the fertility of sows, prolificacy and the number of live-born piglets, it was found that with the same conditions, feeding, timing and methods of weaning piglets, as well as obtaining, evaluating, processing and using the semen of boars, for all experimental and control groups, the obtained results allow to optimize the methods of artificial insemination of sows, by reducing of semen doses volume and amount, and increasing reproductive indicators, maximizing the potential of physiologically mature sows of the 4^th–6^th parity.

Key words: sow, fertility, artificial insemination, semen dose, optimization
