The results showed that the sexual maturity of KM mouse was earlier than that of NIH and ICR,and ICR was the latest.The paranumber of deliveries per socket NIH was more than that of NIH and ICR,and NIH was the least.The milking of NIH and ICR was higher than KM.The average weight of firsbom mice of NIH was higher than that of KM and ICR.After ablactation the weight of NIH increased more fast than that of KM and ICR.

结果提示：KM性成熟比NIH和ICR小鼠迟，ICR小鼠最早；KM小鼠窝产仔数比NIH和ICR小鼠多，NIH小鼠窝产仔数量最少；NIH和ICR小鼠离乳率比KM小鼠高；NIH小鼠初生仔鼠平均体重比KM及ICR小鼠重，离乳后NIH小鼠体重增长比KM及ICR小鼠快。

This study indicated that MⅡ meiotic apparatus or spindle sustains normal structure and function after micromanipulation and electrofusion.

移植产仔率为25％。本项研究获得了MⅡ期核移植成功产仔的结果。这为进行不同年龄和卵龄间的MⅡ期核移植提供了一个模型。

It was found greater expression of NRP2-1 and NRP2-2 in pituitary, ovary, uterus and oviduct of ruttish Erhualian than corresponding tissues of ruttish Duroc, which suggested enhancing expression of NRP2 was favorable to increasing litter size. But the difference of NRP2 expression was not significant between two breeds, which suggested the key phase that NRP2 affected litter size was not oestrum probably, or NRP2 could enlarge cell signals and finally affect litter size ascribe that it was the receptor of nerve axon guidance factors.

NRP2-1和NRP2-2在发情期二花脸卵巢、子宫、输卵管中的表达量均大于杜洛克相应组织的表达量，推测NRP2表达水平高可能有利于提高产仔数，但两品种间表达差异不明显，推测NRP2影响产仔数的关键阶段可能不是猪的发情期；另外，NRP2 是神经轴突介导因子的受体，这些神经轴突转导的信号往往有级联放大的功能，虽然NRP2-1和NRP2-2在二花脸和杜洛克卵巢、子宫、输卵管中的表达差异不大，但二花脸有可能通过神经系统转导信号的级联放大最终引起一些效应激素或蛋白的急剧增加，从而提高排卵率或产仔数。

But on behavioral measures, rat moms perform significantly better on spatial working memory tests than nonpregnant rats, with first-time moms performing the best of all.

但是在行为测量的维度，产仔的大鼠在空间工作记忆测试中的表现明显好过没有怀孕的老鼠，而第一次产仔的大鼠表现最好。

The general linear model via least-squared method was further applied to study the relationship between litter performances described above and the presence of individual allele for parous sows in Landrace, Yorkshire and Duroc breeds.

以一般线性模式和最小平方法分析母猪个别遗传标记交替基因与其产仔性能之结果显示：一些标记交替基因与四个品种母猪的产仔性能有极显著相关并具正效应。

Based on the study, we suggest that the main calving ground requires strict protection from disturbance, and a large reserve in the region needs to be established.

基于本次研究，我们建议新疆和田地区能够对这个产仔地进行严格保护，禁止产仔期的人类干扰，同时有必要考虑建立一个大型保护区，或者和相邻保护区联合起来进行管理。

After the RT-PCR detection of the total RNA from heart tissue, we found that the CD59 gene and MCP gene were expressed. 4. The CD59 gene and MCP gene were mixed with liposome, then used to produce transgenic swine by 3 methods. Firstly, the gene/ liposome complex was directly injected into male swine's testis. The transfected males copulated with 8 females each 44 days later.

其中睾丸注射法处理公猪1头，44d后配母猪8头，7头受孕，产仔73头，结果检测到PCR阳性猪3头(阳性率4.3%)；输精管注射法处理公猪3头，8d后配母猪3头，0头受孕；外源基因/精子共孵育法处理公猪4头，处理母猪4头，1头受孕，产仔11头，结果检测到PCR阳性猪1头(阳性率9%)。

Amur tiger spent most time in moving, more time in rutting, copulating and other behaviors, and less time in resting.

雌虎在妊娠期较多的时间用于休息和运动，取食、站立、社会和其它行为的时间均较少；产仔期最多的时间用于休息，其次是运动，用于产仔和其它行为的时间较多，用于取食的时间最少；哺乳期最多的时间用于休息，其次是哺乳和运动，用于取食和其它行为的时间较少。

The kittening behavior of female Amur tigersin captivity were observed by scanning sampling and all-occurrence sampling methods from the year of 1999 to 2003, which included 3 571 times in the whole 194 373 seconds by 22 tigers in the whole observation.

在黑龙江东北虎林园中，采用扫描取样法和所有事件取样法对半散放东北虎的产仔行为进行了连续5年（1999—2003）的观察。共观测产仔东北虎22头次，观察时间累计194 373秒，观察到各类行为共计3 571次。

Tibetan mastiff litter mate is usually a time 4 - 5, with two second litter mate 7 - 9 Zhi.

藏獒交配1 次通常产仔4 - 5 只，交配2 次产仔7 - 9 只。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
