发情的

Result At the end of dioestrus, the estradiol level was increased gradually, and the peak of estradiol appeared from 1 day before oestrus to 3 days after oestrus (52.50±29.26) pg/mL, then the estradiol decreased rapidly, its lowest value at 6-9 days of oestrus (7.20±5.50) pg/mL. The level of progesterone was low before oestrus, and rose gradually at the peak of estradiol and reached the highest value at 9-15 days of oestrus (35.52±7.87) ng/mL, then it decreased gradually.

结果 发情间期的末期，雌二醇开始升高，在发情前1 d至发情开始后3 d内出现雌二醇高峰(52.50±29.26) pg/mL，峰值后雌二醇急剧下降，到发情第6~9天下降至最低值(7.20±5.50) pg/mL；孕酮水平在发情前期较低，于雌二醇高峰时开始上升，发情第9~15天达到最高值(35.52±7.87) ng/mL，此后逐渐下降。

In infundibulum and ampulla, the mPGES-2 staining from days 3 to 5 was very weak. During estrous cycle, mPGES-2 immunostaining in infundibulum was weak at diestrus and comparatively stronger at estrus. In ampulla, the immunostaining was nagtive in diestrus and weak in estrus.

发情周期中，mPGES-2 蛋白在发情间期伞部弱表达，在发情期伞部较强表达；在发情间期壶腹部不表达，在发情期壶腹部弱表达，与Western blot 检测整个输卵管的结果基本一致。

Methods Blood samples were collected from the precaval vein of 6 female Tibet mini-pigs to test the concentration of sex hormones including T,P4,E2,FSH,LH,PRL and blood biochemical indexes including Ca, Mg, P, ALP, Cre, CHO, TP, and Alb during the estrous cycle.

对6头雌性西藏小型猪在发情周期内的发情当天、第5天、第10天、第15天、再次发情时分别采血5 mL并分离血清，应用放射免疫法测定血清睾酮、孕酮(P4)、雌二醇(E2)、促卵泡生成激素、促黄体生成激素、泌乳素；用自动生化仪测定血清钙、镁、磷、碱性磷酸酶、肌苷、总胆固醇、总蛋白、白蛋白。

Methods: Adult mice of Kunming variety were used as experiment animals. After judgement of oestrus, the oestrus period and oestrus stage were determined, and then those mouse were grouped depending on oestrus stage. The mice were dealed with diferrent dosage of PMSG and HCG to make them superovulation, afterwords were mated individually with the male mouse together at same cage. The embryoes were rinsed out and evaluated after 3.5 days when the plug had been seen. The transplant mice were born after the high-quality embryoes were transferred into the receptors mouse uterus at the same oestrus stage which was stimulated by mating with the male mouse which spermaduct had been ligated previously.

以昆明系小白鼠为实验动物，取性成熟个体，先进行发情鉴定，确定其发情周期及不同的阶段，然后按发情阶段分组，分别用不同剂量的孕马血清促性腺激素和人绒毛膜促性腺激素进行超排处理并与公鼠合笼，在见栓后的第3.5天冲胚，对所得胚胎进行鉴定；将质量较好的胚胎选出，移入同期发情并经结扎公鼠交配刺激后见栓的受体小鼠子宫内，得到移植小鼠。

In the pituitary, the pattern of ghrelin mRNA expression during oestrous cycle markedly decreased in the estrus and metestrus. In the ovary, ghrelin mRNA exhibited with the highest level in the diestrus and the lowest in the proestrus, which was different from those in the hypothalamus and pituitary.

下丘脑ghrelin mRNA的表达在发情前期水平最高（p 0.05），发情期最低；在垂体，发情前期和间情期mRNA表达水平明显高于发情期和发情后期（p 0.01）；而卵巢中Ghrelin mRNA表达模式不同于下丘脑和垂体，在发情前期水平最低，然后逐渐升高，在间情期表达水平最高（p 0.01）。

The changing trend of progesterone during oestrous cycle resembles with that during the first 14d of early pregnancy. Its content reaches the peak value at lOd after oestrus and then declines. The estradiol peak appears at 3d of oestrous cycle, and the level rises again before oestrus. The concentration of LH declines after oestrus. The level of follicle stimulating hormone reaches the peak value at lOd after oestrus (2.40mIU/ml).

发情周期：民猪发情周期孕酮的含量与妊娠早期14天内的变化极其相似，在发情后第10天达峰值，而后开始下降；雌二醇水平在发情后第3天出现高峰，下次发情前开始升高；促黄体素在发情当天达最高水平，然后开始下降；促卵泡素在发情后的第10天达到峰值(2.40mIU/ml)。

Finally, the computer monitoring system was installed into a computer equipped with a data-collecting device. By using the system, the oestrus of dairy cattle could be predicted and forecasted timely and accurately.

将奶牛发情计算机监测系统安装于与数据采集设备相连的过程计算机中，对奶牛发情进行实时监测并做出及时准确的奶牛发情预报。

It is what biologists callan unfakeable signal, like the deep roar of a big, rutting stag

这些都是生物学家所称的伪造不了的信息，就象一头发情的牧鹿的低沉吼叫，年龄小的青少年们的身体上是无法展现出来的。

One Beltane Eve, a very long time age, the young men of the village would go into the woods and donstag horns and skins in kind of "play fight" with the rutting stags to see which was bravest.

很久很久以前，在五朔节的前夜，村子里的男人会到树林里去，头戴雄鹿角，身披雄鹿皮，然后与正在发情的雄鹿打一种&游乐仗&，比一比谁勇敢。

Thus, in 9 - 11 during the month to focus on estrus and breeding.

因此，在9 - 11 月份期间，能集中发情和配种。2 - 5 岁河曲母藏獒，在9 - 11 月份都能集中发情，占发情母獒总数的83 。
