The aim of this paper is to follow the results of sows’ cervical inoculation with doses containing 2, 3, 4 and 5 billion mobile sperm/ dose and sows intrauterine inoculated with 2 billion sperm. There were inseminated 256 gilts and 408 sows divided in 8 groups depending on the motile spermatozoa number/ dose and age category. The sows which were cervically inoculated with 3, 4 and 5 billion sperm had a fecundity between 93.33% and 96.38%, while sows inseminated with 2 billion sperm, the fecundity decreased to 85.9%. To the intrauterine insemination with 2 billion sperm was noticed a fecundity of 96.03%.enCC BY-NC-SA 4.0https://creativecommons.org/licenses/by-nc-sa/4.0/sowsnumber of spermatozoa/inseminationfecundityArticle2821 - 6644
