Sows generally are anoestrus during lactation. Weaning the litter normally results in a rapid increase in follicular growth that terminates in oestrus and ovulation. Follicular development after weaning is characterized by an elevation in the blood concentrations of oestradiol-17ß (E). Although the post-weaning patterns of E in blood circulation have been reported previously 1982, 1983, 1988), the plasma patterns of E in relation to the interval from weaning to oestrus (WOI), to our knowledge, have not been assessed. The purpose of this study was therefore to relate the blood patterns of E to the WOI in sows exhibiting their first oestrus within 10 days after weaning.
母猪在哺乳期通常处于乏情期。仔猪断奶通常会导致卵泡生长迅速增加，最终引发发情和排卵。断奶后的卵泡发育特征是血液中雌二醇-17β（E）浓度升高。尽管此前已有关于断奶后血液循环中E的模式的报道（1982年、1983年、1988年），但据我们所知，尚未评估与断奶至发情间隔（WOI）相关的血浆E模式。因此，本研究的目的是将E的血液模式与断奶后10天内首次发情的母猪的WOI联系起来。
