摘要
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 (PGF2a) 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.

这项研究的目的是评估的初产和多子萨能山羊后腹腔镜宫内人工授精与冷冻精液繁殖性能。二十四萨能山羊，2组分为：第1组包括11个初产山羊和2组包括了13多子山羊。发情期由20毫克fluorogestone醋酸（FGA）-impregnated阴道海绵和125毫克氯前列烯醇（PGF2a含量）和心电图（400 IU）的海绵去除前48小时的IM管理同步。宫内固定时间人工授精（AI），进行除去FGA海绵后55小时。本研究的结果表明，初产萨能奶山羊表现出更高的怀孕率比多子山羊。然而，怀孕和受孕率没有初产和多子山羊（66％和53％之间的显著差异; P在多子和初产山羊腹腔镜宫腔内人工授精的技术是农村的条件下成功地使用。
