氯前列烯醇诱导黄牛同期发情效果试验

Cloprostenol Induced Heat in the Same Period Cattle Test Results

氯前列烯醇是PGF2α的类似物，在目前常用的PGF2α及其类似物中，其活性最高。本试验应用氯前列烯醇对农牧民分散饲养的母牛进行同期发情效果观察。结果表明在24～72h内92%的母牛发情，经直肠检查发情母牛排卵率为86％，情期受胎率为62％。说明氯前列烯醇对诱导母牛同期发情处理效果显著。

Cloprostenol（CLO,an analog of PGF2α）is the highest active in the PGF2αand its analogue that we often used. This study was carried out to induce estrous synchronization with CLO in which cows were decentralized breeded by herdsmen and observed the effect. Results showed that the oestrus rate is 92% after treated with 24 to 72 hours,the ovulation rate is 86% by rectal examination, and cycle conception rate is 62%. The effect is evident to induce estrous synchronization with CLO in cows.
