【摘要】：【目的】超排胚胎移植技术是提高绵羊遗传潜力的一项重要应用技术,但影响供体超数排卵的因素很多,也需要大量数据支持。【方法】以影响供体超排的因素做回顾性调查分析,从激素来源、肉羊品种、日粮水平、年龄、超排间隔和超排剂量等6个方面观察对供体超排的影响。【结果】国产FSH超排效果与进口FSH差异不显著(P0.05),肉羊品种间无显著差异性(P0.05),年龄对供体超排反应影响显著(P0.05),营养对供体的超排反应显著(P0.05),供体以短间隔超排重复利用获得胚胎数量最多,增加超排剂量能显著改善超排反应(P0.05),但对重复利用供体差异不明显(P0.05)。【结论】对超排反应有影响的因素分为显著的和不显著的因素,显著的因素包括年龄、营养、超排间隔、超排剂量,而不显著的因素为品种。
[Abstract]:[objective] superovulation embryo transfer technique is an important applied technique to improve the genetic potential of sheep, but there are many factors that affect the superovulation of donor. It also needs a lot of data to support. [methods] the factors affecting donor superovulation were analyzed retrospectively, from hormone sources, breeds of meat sheep, dietary level, age, [results] there was no significant difference in superovulation effect between domestic FSH and imported FSH. There was no significant difference between sheep breeds and sheep breeds, and age had a significant effect on donor superovulation. [results] there was no significant difference between domestic FSH superovulation and imported FSH, and age had a significant effect on donor superovulation. The response of nutrition to donor superovulation was significant (P 0.05), and the number of embryos obtained by short interval superovulation was the highest. Increasing the superovulation dose can significantly improve the superovulation response (P0.05N), but there is no significant difference in the reused donors. [conclusion] there are significant and unsignificant factors affecting the superovulation response. The significant factors include age, nutrition, and superovulation interval. Superovulatory dose, but not significant factor for variety.
