摘要： 试验选用优质进口催情激素药物处理112头乏情母猪，研究结果表明，母猪的胎次和膘情对于外源激素的繁殖调控效果有明显的影响：（1）在母猪胎次分组中，后备猪与经产猪的促发情率分别为80%和92.3%，配种分娩率分别为25%和58.33%。（2）在膘情分组中，各组的促发情率除了膘情过肥母猪最低（20%），其他组为100%；配种分娩率中膘情过肥和过瘦母猪最低（0），而膘情适中、偏肥和偏瘦组的分别为6.15%，31.25%和68.75%。

Abstract: One hundred and twelve anestrus sows were injected with the high quality reproductive hormone(FD-600).The results showed that the effects of parity and fatness of sows on the reproductive regulation of exogenous hormone were significant.(1) The estrus rate and the farrowing rate of gilts were 80% and 25%,and that of the mutiparous sows were 92.3% and 58.3%.(2) The estrus rate of the fattest sows was the lowest(0),and that of the others was 100%.The farrowing rate of the fattest and thinnest sows was the lowest(0),and the farrowing rates of mid fatness sows,fatter sows and thinner sows were 46.15%,31.25% and 68.75%,respectively.
