发情的

Based on the estrus synchronization and its detection,in the research Red Deer was subjected to artificial insemination.

The goals of this article is to investigate impact and manchisms on reproductive capability in prepubertal gilts and primiparous sows by feeding of short-term restriction.

属性不符本文旨在研究不同能量水平和来源对后备母猪体成分、发情率、初情日龄和发情表现的影响。

E. staining and other techniques were used to elucidate the pattern of follicular development, atresia, changes in follicle number on the ovarian surface, proportions of apoptotic granulosa cells in follicles of different sizes and morphological changes of atretic follicles, as well as changes in serum estradiel and progesterone levels at different stages of the porcine estrous cycle.

为探讨猪发情周期不同时期卵泡发育和闭锁的规律及机理，本实验通过TUNEL原位标记、H.E。染色以及放射免疫测定等手段研究了猪发情周期不同阶段卵巢表面各类卵泡数量的变化、各类卵泡中颗粒细胞的凋亡比例、闭锁卵泡的形态变化以及发情周期各阶段血清孕酮及雌二醇水平的变化等问题。

The period of behavioral estrus is variable, and often extends up to several days before and/or after cytologic estrus.

这一时期的行为发情是可变的，而且往往延伸到数天前和/或细胞学后发情。

All results above indicated that:The expression of ERβand p-ERβin mouse ovary at oestrous cycle and in early gestational period changed regularly, it showed that ERβand p-ERβhad important effects to ovaries development, ovarian follicles groth, oocyte maturation and form corepus luteum in female mouse ovary during oestrous cycle and in early gestational period.

以上结果表明：ERβ及其磷酸化形式——p-ERβ在小鼠发情周期以及妊娠早期卵巢中表达有规律性的变化，揭示ERβ与p-ERβ在雌性小鼠发情周期及妊娠早期，对卵巢发育、卵泡生长、卵母细胞成熟和黄体形成有重要的作用。

Vagina sponge bolt and CLO was used in oestrous synchronization of donors and acceptances , the rates of estrus was100.0% and 83.0%. 6mg FSH and CLO was used in superovulation of Hexi Fine wool goat,115 embryos were acquire totally and average14.4 embryos,100 useful embryos, average 12.5 embryos.The surgical operation used in embryos transplant, the rate of Gestation was 82.4%, 47 lambs was birth,and the birthrate of lamb was 167.9%.

采用阴道海绵栓结合氯前列稀醇法对供、受体进行同期发情处理，处理结果的发情率分别为100.0%和83.0%；采用 FSH剂量6m g/只结合氯前列稀醇对河西绒山羊超数排卵，共回收胚胎115枚，头均14.4枚，可用胚胎100枚，头均12.5枚；采用手术法对杂种河西绒山羊受体移植后，妊娠率82.4%，产羔47只，产羔率为167.9%。

The testing methods and targets were shown as below:Recorded milk weights from the 7th day postpartum to 15th day postpartum,and calculate the average day-milk yield;Milk samples were draw in 7th day and 14th day postpartum,and testing the milk fat,milk lactose,milk protein,milk Zn and the milk somatic cell counts;Blood samples were adopted at the 7th day postpartum,testing the levels of serum PRL; Blood samples adopted at the 1st day and the 12th day in oestrous cycle were used to test the levels of E_2 and P_4 in serum;In the experimental stage, registering the condition of parturition, the mean birth weight of calves,the first oestrus,the oestrus scycle postpartum and the conception rate of the first service after artificial insemination.

试验方法及所测指标如下：于产后第七天到第十四天记录日产奶量，最后计算每组平均日产奶量；每组随机抽取分娩后第七天、第十四天的奶样，测定乳糖、乳蛋白、乳脂、乳锌含量及乳体细胞数；于产后第七天，随机采取奶牛血样，测定血清中PRL含量；于发情周期的当天和第12天，随机采取血样，测定血清中雌二醇(Estradiol，E2)和孕酮(Progesterone，P)的浓度；记录奶牛的分娩情况、犊牛初生重、产后第一次发情日期、产后发情周期，并采用人工授精技术进行受精，记录第一情期受胎率，最后取平均值，作为衡量奶牛繁殖性能的指标。

The oestrus rate of ewes in high, middle and low nutrition level groups were 83.33%, 100.00% and 33.33% respectively.

上述结果表明，中等能量蛋白质营养水准能较好促进母羊的发情，缩短母羊产后的发情时间。

Diestrus: Lasting 60 to 90 days, diestrus is the period when the reproductive tract is under the control of the hormone progesterone.

发情间期：这段时期持续约 2-3 个月。发情间期，母犬生殖系统处于妊娠激素的调控之下。

Estrum of wild sow belongs to seasonality and often estrus in October to November.

母野猪发情有季节性，大约在每年的10～11月份；公野猪发情无季节性，可以常年配种。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
