MILLER, Joana et al. Sperm concentration on the intrauterine artificial insemination in swine. Ciênc. agrotec. [online]. 2009, vol.33, n.6, pp.1671-1674. ISSN 1413-7054.

The aim of this work was to evaluate the efficiency of the intrauterine insemination (IUI) in swine, considering the conception rate, farrowing rate, litter size (alive born pigs). For the IUI, the females had been insemination at 24 and 48 hours after the estrus detection, and the inseminating doses of 500 million, 1 billion, 1.5 billion and 2 billion spermatozoa in 20 mL extender had been used. The procedure of catheter insertion through the cervical canal was successfully performed in 97.9% of the females. The conception rate was 6.3% in the IUI. The farrowing rate in IUI was 87.2% but the farrowing rate was 100% for the sperm concentration of 500 million. Regarding the number of born pigs and alive born pigs observed in females inseminated with IUI, no significant difference was observed (p > 0.05). The concentration of 500 x 106 spermatozoa in 20 mL extender in the intrauterine insemination resulted in an optimal reproductive performance.

Keywords : Intrauterine insemination; reproductive performance; sperm cell dose.
