For the proposed research were used doses of semen obtained from two PIC boars and one Large White boar. Observations were extended from 16 months old boars up to 33 months. With the semen collected from the three boars were inseminated 567 half-breeds sows accommodated in household system. Sows were divided into two groups: the L1 group - comprising sows inseminated with 4 billions mobile spermatozoids /dose and L2 group - comprising sows inseminated with 2.5 billions mobile spermatozoids/dose. The average fecundity of sows in L1 group was 83.6%, insignificantly higher than that of sows in L2 group (82.4%). The average number of piglets obtained/farrowing at sows in L1 group was with 0.22 piglets higher than the number of piglets obtained at sows in L2 group (8.60 ± 0.2 piglets for L1 group; 8.38 ± 0.1 piglets for L2 group). The results show that the reduction from 4 billions to 2.5 billions the number of mobile spermatozoids/dose does not diminish the results of insemination.
