Intrauterine insemination was done in three flocks comprising 207 sheep. The efficacy was determined on the basis of lambing using a frozen and fresh semer. The assessment of ovaria of sheep females was done after 59—68 hours since the removal of uterine sponges (Intervet) and the administration 660 i.u. of PMSG. The semen was frozen according to Aamdal’s method and was thawed at 60°C. The semen was administered in animals on condition that its mobility was 50 per cent and applied within 1,5 hour since thawing. The fresh semen was used within 3 hours since its collection by an artificial vagina. A milk diluent, a dose containing 20 or 100 X 10⁶ spermatozoons in 0.4 ml and stirring small balls or ejaculates taken from 3 rams were the same for the both kinds of semen. The efficacy of hormonal stimulation was assessed in 154 sheep and it was 91 per cent. Fertility in ewes after insemination before and after ovulation was 63 and 45 per cent, respectively. On an average after intrauterine insemination 48.8 per cent of lambing was obtained: using a fresh or frozen semen the percentage of lambing was 37.8 and 54.9 respectivedy (P ≤ 0.05). No differences were observed depending on semen doses or flocks — Merino 44 per cent, Pogorze 47 per cent, Friesian 64 per cent.
