estrus n.【動物;動物學】發情期。

estuarial

Amy da release of proestrus female rats was apparently higher than estrus , metestrus and ciestrus female rats , but no significant difference was observed among estrus , metestrus and ciestrus female rats . da release in ovx rats was higher compared with male rats , but lower than proestrus female rats . no difference appeared among ovx rats and estrus , moiestrus , ciestrus female rats 電刺激vta誘發的雄鼠amyda釋放量明顯低于雌鼠和ovx鼠;處于動情前期雌鼠的amyda釋放量高于動情期、動情后期和動中文摘要情間期雌鼠;而動情期、后期及間期雌鼠間da釋放量差異無統計學意義; ovx鼠da釋放量高于雄鼠,低于動倩前期雌鼠,但與動情期、后期及間期雌鼠比較無顯著差異。

In the present study , in order to investigate the effects of endogenous estrogen on the daergic terminals in amy and the daergic neurons in midbrain , fast cyclic voltammetry ( fcv ) was used to examine da release evoked by electrical stimulation from amy of female rats in different phases of estrus cycle , ovx rats and male rats . and tyrosine hydroxylase ( th ) immunohistochemi stry was employed to measure the numbers of daergic neurons of ventral tegmental area ( vta ) and substantia nigra ( snc ) in the rats 因此,為進一步探討大鼠內源性雌激素水平的變化對amyda能神經系統及中腦da能神經元的影響,本工作應用快速周期伏安法( fcv )在體監測了處于動情周期各期雌鼠、 ovx鼠和雄鼠經電刺激誘發的amyda釋放,并應用酪氨酸羥化酶( th )免疫組化方法測定了以上各組大鼠腹側背蓋區( vta ) 、黑質( snc )的th陽性神經元數目。

The disease , low quality of embryo , semen contamination , breeding out of time , low quality of recipient , not synchronous estrus between donor and recipient , antiquated preserve to embryo , hereditary unsoundness , accidental injury by medicament , vaccination , feeding and management to depart from science , immunological reaction and multiple embryo in uterus are the more important factors 這些因子主要包括疾病、胚胎質量差、精液污染、不適時配種、受體羊質量差、供受體羊發情不同步、胚胎保存時間長、遺傳缺陷、誤用藥物、接種疫苗、飼管不科學、免疫反應、子宮內多胚等。

Recently , giant panda jin zhu got estrus , and very bad fighting with other male pandas , her ear got hurt , with the treatment from the staff , it has already healed 前段時間大熊貓錦竹發情期間因為自身特殊原因,與種公貓相互打架,導致耳朵很受傷。經過科研人員的精心治療,現在耳朵已經痊愈。

Action and use it significantly enhances mature follicle ovulation and induces luteum to continue production in female animals . it can stimulate female animals into estrus 本品可促進雌性動物成熟卵泡排卵和黃體生成,延緩黃體的存在;并能刺激卵巢分泌雌激素而引起發情。

The staff from mianning county said , after the good care from their staff , it is not in dangerous now , eat food , drink , and suppose to get estrus 據來自冕寧的管理人員介紹,該貓經悉心照料,已經脫離生命危險,身體狀況較好,能正常進食、喝水、排便,可能有發情跡象。

It significantly enhances mature follicle ovulation and induces luteum to continue production in female animals . it can stimulate female animals into estrus 本品可促進雌性動物成熟卵泡排卵和黃體生成,延緩黃體的存在;并能刺激卵巢分泌雌激素而引起發情。

Progesterone levels remain elevated for 8 to 10 weeks following estrus in order to thicken the lining of the uterus in preparation for pregnancy 黃體酮的水平會在發情期之后的八到十周內持續增高,以加厚子宮內膜,從而為懷孕做準備。

Bitches have their first estrus ( also know as season or heat ) after six months of age , although it can occur as late as 18 months to two years of age 一些在母犬六個月齡后就會有第一次發情,有些則會遲至18個月甚至兩歲。

A female comes into estrus a week or two after giving birth and , if she is not fertilized then , again about a month later 生產后的雌馬會在1 ~ 2周后進入發情期,如果這段時間沒有懷孕,大約一個月后會再發情一次。

Typically , it occurs about 1 to 2 months after estrus , or when the cat comes into heat 母貓在進入發情期后的一到兩個月,或者是開始發情時,特別容易出現這種病癥。

Study of reproductive hormone on the synchronization of estrus of small - tail sheep 應用生殖激素對小尾寒羊同期發情效果研究

Estrus recurs at intervals of approximately six months until late in life 從一個發情期至第二個發情期之間約為六個月。

During estrus , the female is fertile and will accept a male 在發情期,母犬可以接受交配并且具有生育能力。

In cows and many other animals, the female is in estrus just before ovulation . 母牛和許多其他的雌性動物都正好是在排卵前發情。

The next estrus was delayed . 下一次發情推遲了。

A cow's estrus cycle averages 21 days . 母牛的發情周期平均為21天。
