母猪

In my experience when pregnancy does occur in the sow during lactation, then agalactia occurs.

根据我的实验研究，如果泌乳期间妊娠，母猪就会发生无乳。

The one-step nurse system involves taking three-week-old piglets off a sow and replacing them with two or three piglets of four or five newly farrowed sows, after first ensuring that they all have had that vital colostrum.

一个步骤护士制度涉及到3周大的仔猪引发母猪，更换两个或三个仔猪四，五个新farrowed母猪，先确保他们都已经是至关重要的初乳。

In the study by Taras et al.(2005), one group of sows were fed for a period of 17 weeks, from day 24 aftermating to day 28 after farrowing, and the piglets from these sows were fed for 6 weeks, from day 15 of lactation to 8 weeks of age.

此研究中，一组母猪饲喂17周，从配种后24小时到产后28天，这些母猪所产的仔猪饲喂6周，从哺乳15天到8周龄。

In summary, the maternal behavior was affected by farrowing environment, neuroendocrine, genetic background and farrowing experience.

就分娩环境、机体内分泌、母猪遗传背景及产仔经验等影响分娩母猪母性行为的4个主要因素进行综述和讨论。

This report attempts to objectively summarize, in lay terms, the current status of housing and penning systems for gestating sows.

我们这篇报道则主要是客观的简要总结一下现行市场上有关饲养大母猪和小母猪的居住供给的情况。

Normally sows are inseminated 24 hours apart, although sows with long heats may be inseminated three times.

通常的母猪配种，隔24小时，虽然母猪长加热，可受精的3倍。

The situation for pigs is no better. About half the world's pigs are crowded into airtight pigsties. Sows are incessantly forced into artificial pregnancy and they can only remain on their sides breastfeeding. Not yet grown, the piglets are forcibly separated from their mothers by butchers to be slaughtered and sold as suckling pigs.

猪的情况也好不到那里，世界一半左右的猪都挤迫在密不透风的猪圈里，母猪被迫不停的人工怀孕，产下小猪也只可以侧在笼内哺乳，小猪未成长又被强行与母猪分离，被屠夫宰成乳猪只售卖。

If boars and sows are housed together, any sows that are more than four weeks old may already be pregnant.

如果公猪，母猪是居住在一起，任何超过四个星期大的母猪都可能已经怀孕了。

Gilts were slaughtered on day 12, 25 and 35 of pregnancy, and serum, uterine flushings, embryos and endometria were collected. ELISA was adopted to determine the progesterone concentration in serum and uterine flushings, and RT-PCR was adopted to determine the genes expression in embryos and endometria.

母猪配种后随机分到3个组，按2.0倍、1.2倍和0.6倍维持需要供给饲粮（分别为采食高、中、低水平），妊娠12、25和35d屠宰母猪，收集血清、子宫液和胚胎、子宫组织，运用ELISA测定血清和子宫液中孕酮浓度，用RT-PCR测定目的基因在胚胎和子宫内膜中的表达。

Sows housed on plastic-coated, expanded metal or woven wire floors consumed about 0.5 kg less than sows housed on highly conductive floor surfaces such as metal i.e.

圈养在塑料包裹的膨胀金属或铁丝网地面的母猪比在高传导地面象金属或混凝土地面的母猪少采食0.5公斤。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
