| 摘 要： | 目前,超数排卵和胚胎移植技术是良种奶牛快速扩繁的最佳手段和途径,但有人担心超数排卵、采卵等不良刺激会对供体牛的产奶量和繁殖性能产生不良影响.2003-2004年对90头供体牛超数排卵和采卵后的繁殖情况和产奶量进行了记录,并与未经超排的成乳牛和育成牛进行比较,发现超数排卵与采卵对供体牛的产奶量和繁殖性能均无显著影响.

| Abstract: | We had a record of milk yield and breeding situation of 90 cow subjects, which had been offered the exceeding ovulation and embryo transplant technology during 2003 and 2004. Comparing this with that of the dairy cattle and adult cow without any stimulation, we find that exceeding ovulation and ovum culling has no remarkable effect on the milk yield and breeding capability of the cow subjects. |
