为了提高博乐某繁育场安格斯母牛受胎率,繁育场采用国内较先进的阴道埋栓技术[1]及用孕激素(戈那瑞林(GnRH))与前列腺激素(氯前列醇钠(PG))结合处理的同期发情技术[2-3],历时两个月分两批对984头母牛进行同期发情处理。其中阴道埋栓分为两种[4],第一种埋栓(CIDR)144头,第二种埋栓(CUEMATE)埋栓175头,合计319头。在二月初,由专业技术人员利用B超技术对984头牛进行孕检,其中怀孕母牛366头,怀孕率达到38%,达到预期标准。通过这次同期发情处理,使得该场母牛受胎率提高了不少,节约了成本,并且为了更科学的使用阴道栓,对比了CIDR与CUE-MATE在使用相同同期发情方案的受胎率[5]。

To improve the fertility rate of Angus cows in a breeding farm in Bole, the simultaneous oestrus technology[2-3]that combines the advanced vaginal embolization technology[1]and progesterone(Gornreline(GnRH)) and prostaglandin(sodium cloprosate(PG)) was used and 984 cows were treated with estrus in two batches over two months, of which, vaginal embolization is divided into two types[4], the first is embedding(CIDR) for 144 cows, and the second one(CUE-MATE) for 175 cows with a total of 319 cows. At the beginning of February, 984 cattle were tested for pregnancy by professional technicians using B-ultrasound technology, including 366 pregnant cows, and the pregnancy rate reached 38%, which conformed to the expected standard. Through such estrus treatment, the cow's conception rate had been greatly increased, the cost was saved, and the conception rate[5]of CIDR and CUE-MATE with same concurrent estrus program was compared in order to use the vaginal suppository more scientifically.
