Reproductive performance of primiparous and multiparous Saanen goats after laparoscopic intrauterine insemination: a field study


Abstract: The objective of this study was to evaluate the reproductive performance of primiparous and multiparous Saanen goats after intrauterine laparoscopic artificial insemination with frozen semen. Twenty-four Saanen goats, divided in 2 groups: group 1 consisted of 11 primiparous goats and group 2 consisted of 13 multiparous goats. Estrus was synchronized by 20 mg fluorogestone acetate (FGA)-impregnated intravaginal sponges and the IM administration of 125 mg of cloprostenol (PGF2\alpha) and eCG (400 IU), 48 h before sponge removal. Intrauterine fixed time artificial insemination (AI) was carried out 55 h after removal of the FGA sponges. Results of the present study indicate that primiparous Saanen goats exhibited a higher pregnancy rate than multiparous goats. However, pregnancy and conception rate did not differ significantly between primiparous and multiparous goats (66% and 53%; P > 0.05). In conclusion, the technique of laparoscopic intrauterine insemination in multiparous and primiparous goats is used successfully under rural conditions.
