进行当前的研究以确定相对于山羊发情发作的人工授精和阴道粘液特性的最佳时机。是否使用荷尔蒙疗法使（n = 257）发情同步。发情后0、12、24和36小时进行新鲜精液的人工授精。观察阴道粘液的特征（即颜色，稠度和体积），并在AI时进行分级，以计算累积粘液评分。AI时记录阴道电阻（VER）（检测器）。发情发生后0 h（28.6％）进行授精的妊娠率较低（P <0.05），而发情后12 h（58.3％）和24 h（56.4％）的受孕率较低。然而，与0时的受精相比，36个小时的受孕率（54.5％）没有差异（P> 0.05），发情后12或24小时。与0小时相比，在12、24和36 h时怀孕率的相对几率分别高出5.24、5.20和3.29倍。相对于发情发作，粘液累积分数变化（P <0.05），并且颜色和稠度比粘液体积好（P <0.05）。发情后12小时的VER小于0和36小时（P <0.05）。总之，发情开始后12-36小时之间可以授精山羊。但是，在12或24小时内进行授精会增加怀孕的机会。发情后12小时的VER小于0和36小时（P <0.05）。总之，发情开始后12-36小时之间可以授精山羊。但是，在12或24小时内进行授精会增加怀孕的机会。发情后12小时的VER小于0和36小时（P <0.05）。总之，发情开始后12-36小时之间可以授精山羊。但是，在12或24小时内进行授精会增加怀孕的机会。

Optimal timing of artificial insemination and changes in vaginal mucous characteristics relative to the onset of standing estrus in Beetal goats.

The current study was conducted to determine the optimal timing of artificial insemination and vaginal mucous characteristics relative to the onset of estrus in goats. Does (n = 257) were estrous synchronized using hormonal treatments. Intracervical inseminations with fresh semen were performed at 0, 12, 24 and 36 h after the onset of estrus. Characteristics of vaginal mucus (i.e., color, consistency, and volume) were observed and graded at the time of AI to calculate cumulative mucous score. The vaginal electrical resistance (VER) was recorded (Draminski® detector) at the time of AI. Pregnancy rate was less (P < 0.05) when inseminations occurred at 0 h (28.6%) compared with 12 (58.3%) and 24 h (56.4%) after the onset of estrus; however, pregnancy rate at 36 h (54.5%) did not differ (P> 0.05) compared with inseminations at 0, 12 or 24 h after estrous onset. Relative odds for pregnancy rate at 12, 24 and 36 h were 5.24, 5.20 and 3.29 times greater compared with 0 h. Cumulative mucous score varied (P < 0.05) relative to the onset of estrus and correlated well (P < 0.05) with the color and consistency than volume of the mucus. The VER was less (P < 0.05) at 12 than 0 and 36 h after estrous onset. In conclusion, goats can be inseminated between 12-36 h after the onset of estrus; however, the chances of pregnancy are greater with inseminations at the 12 or 24 h time periods.
