摘要: 以宜昌白山羊为研究对象,探索了促卵泡素(FSH)不同剂量的超排效果。结果表明,CIDR+FSH+PG法处理宜昌白山羊,同期发情率100%,随着FSH剂量的增加,超排处理的宜昌白山羊黄体、回收胚胎和可用胚的数量增多。当FSH注射剂量为18 AU/只时,6月龄宜昌白山羊平均排卵点为18.60个、回收胚胎15.60枚,其中可用胚14.20枚;12月龄羊平均排卵点为20.00个、回收胚胎16.25枚,其中可用胚14.00枚。因此宜昌白山羊超排处理的适宜FSH剂量为18 AU/只。FSH剂量为18 AU/只时,6月龄羊的超排效果与12月龄羊之间没有明显差异,说明宜昌白山羊性成熟即可进行超排处理,该研究结果可为同期发情、超数排卵在宜昌白山羊产业化中的应用提供参考依据。

Abstract: Yichang white goats were selected to study the effects of different FSH dosages on superovulation. The results showed that the rate of synchronization estrus was 100% and the number of corpus luteum, collected embryo and effectiveembryo increased with the increment of FSH dosage. When injected 18 AU FSH per goat, the corpus luteum, collected embryos and effective embryos of 6-month-old goats was 18.60, 15.60 and 14.20, respectively while of the 12-month-old goats was 20.00, 16.25 and 14.00, respectively. And the superovulation effects had no significant difference between 6-month- and 12-month- goats. It suggested that the Yichang white goat could be treated superovulation at 6-month-old and the suitable FSH dosage of superovulation for 6- and 12-months old goat was 18 AU/head.
