摘要： 本研究共进行了2个试验。试验Ⅰ，成年布尔山羊在繁殖季节初期经超排处理，平均每只采得有效胚胎17.07枚，2个月后再行重复超排处理，虽有3只羊未能实现采卵，但其它羊只均获成功，其中B组（FSH加量）平均获有效胚胎15.46枚，明显高于A组（FSH未加量，平均每只12.93枚）。试验Ⅱ，选择了2000年超排效果较好的布尔山羊，在2001年和2002年秋季进行了第2次、第3次重复超排处理。结果表明：在生殖器官未发生粘连的情况下，第2次平均获有效胚胎15.83枚，与第1次超排结果（平均15.50枚）相近。第3次超排因两只羊生殖器官粘连未能采卵，其余10只羊平均采得有效胚胎13.40枚。

Abstract: There were two experiments in this study . In trialⅠ,average 17.07 available embryos were collected from 12 Boer goats treated for super-ovulation at the beginning of reproductive season. After two months all of them were divided into two groups for repeated super-ovulation. The dose of FSH was not changed and 12.93 available embryos were collected from each donor(14 available donors)in group A. But the dose of FSH for group B was increased by 30% and average 15.46 effective embryos were collected from group B(13 available donors) . There were still two donors from group A and group B separately that could not give us any chance to collect ova because of adhesion of reproductive organs. In trial Ⅱ, 12 Boer goats which gave us more effective embryos in 2000 were chosen for the second and third time repeated super-ovulation in the autumn of 2001 and 2002. Average 15.50 available embryos were gathered from the 12 goats in the second year. It was same as what in the first year. Average 13.40 embryos were gathered from the 10 donors and another two goats had not been used due to adhesion of reproductive organs in the third year.
