摘要
为探讨最佳的超数排卵方案,提高胚胎移植效率,试验以波尔山羊为研究对象,比较了不同超排方法、超排次数、超排季节、授精方式及生育状况等因素对供体超排效果的影响。结果表明:不同超排方法对超排效果有显著影响(P<0.05);经两次超排处理的供体所得可用胚数显著的高于未经过超排过的羊只(P<0.05);经一次超排处理的供体可用胚比例显著高于未经过超排过的羊只(P<0.05);而授精方式、超排季节、生育情况等因素对超排效果没有显著影响(P>0.05)。
To study the optimal process of superovulation and improve the efficiency of embryo transfer, one of the factors influencing effects of superovulation in Boer goat, methods of superovulation, times of superovulation, methods of insemination, season of superovulation and parity of donor were studied in this trial. The result showed that the different methods had a significant effect on superovulation （P〈0.05）. The mean number of viable embryos in second and the rate of viable embryos in first repeat superovulation were significantly more than that of donors without treatment （P〈0.05）. Methods of insemination, season of superovulation and parity of donor did not affect the results of superovulation significantly （P〉0.05）.
