黔北麻羊超数排卵效果分析

目的]探索适宜的地方山羊品种超数排卵方案。方法]以黔北麻羊为试验动物,比较不同品牌促卵泡素(FSH)、相同品牌不同剂量FSH的超数排卵效果。结果]41只黔北麻羊的平均黄体数14.59个,平均有效胚数8.39枚。日本产FSH 20.0 AU/只剂量组平均黄体数13.90个,平均有效胚数10.21枚;加拿大产FSH 160 mg/只剂量组平均黄体数14.00个,平均有效胚数7.33枚。结论]日本产FSH的适宜剂量为20.0 AU/只,加拿大产FSH的适宜剂量为160 mg/只,日本产FSH的超数排卵效果优于加拿大产FSH,但差异不显著。

Analysis of Superovulation Effect of Qianbei Brown Goat

Objective] To explore the optimal superovulation scheme for local goats.Method] Taking Qianbei brown goat as test amimals,the superovulation effects among different brands of FSH,same brand FSH with different dosages were compared.Result]The luteum (CL) number of 41 Qianbei brown goats was 14.59,the number of effective embryos was 8.39.In the group of Japanese FSH with the dose of 20.0 AU/head,the luteum (CL) number was 13.90,the number of effective embryos was 10.21.In the group of 160 mg/head FSH from Canada,the luteum (CL) number was 14.00,the number of effective embryos was 7.33.Conclusion] The appropriate dose of FSH from Japan was 20.0 AU/head,the suitable dose of FSH from Canada was 160 mg/head,and the superovulation effect of FSH from Japan was better than that of FSH from Canada,but there was no significant difference.
