产仔

In the months leading up to the big event, try to witness a whelping, perhaps with the breeder of your own bitch or with another experienced breeder in your area.

在经历爱犬产仔前需要做些准备工作，你可以先去看其他犬只是如何分娩的，这可以是你母犬的饲主一起，也可以和当地有经验的繁殖者。

In the field of long-term antifertility, castor bean extract is of good effect which decreased mice's production and generations within 210 d (mice's normal gestation period is 21~23d).

蓖麻油长期抗鼠生育效果明显，在210d（正常小鼠的妊娠期是21~23d）内有效降低小鼠生育代数与产仔数，生育抑制率达80%以上。

If the foetus is infected at less than 35 days of age, before there has been an opportunity for bone development, death results, followed by complete absorption and ultimately a small litter is born.

如果胚胎在35天之前感染猪细小病毒会发生胚胎死亡，由于此时胎儿的骨骼尚未发育完全，死胎随后将被完全吸收。结果会导致产仔数减少。

My flocks feed not,My ewes breed not,My rams speed not,All is amiss.Love is dying

我的羊群无人饲养了，我的母羊不再产仔了，我的公羊不再快跑了，一切都错了。

Although it would be impractical for most producers to convert their operations to a wet feeding system, the simple act of mounting the water nipple in the farrowing crate directly over the feed hopper can help to stimulate sow feed intakes.

虽然让大多数猪场转变成湿喂操作系统是不现实的，但是简单湿式可直接在产仔箱的料槽里安装乳头饮水器也能刺激母猪采食量。

First, they must survive their migration from the calving grounds off the coasts of Florida and southern Georgia — where airplanes were used to count and photograph them — through East Coast shipping traffic to their summer habitat around Canada's Bay of Fundy.

首先，幼鲸出生后要从佛罗里达海岸和南乔治亚州海岸附近的产仔地，迁徙到加拿大芬迪湾附近的夏季栖息地，其间，它们要经过美国东海岸无数船只交汇成的水上交通网，能顺利完成迁徙的幼鲸才能活下来。

In conclusion, the number of born alive per litter was not affected by the half-sib mating method after two generations of selection in the homozygotic GPI/PGD line of Lanyu pigs.

结果显示兰屿猪种GPI/PGD遗传型纯合品系采半同胞配种和两个世代选拔后，进亲配种并未影响到母猪的产仔数。

It was tough gettin this time -- some a them late heifers is still calvin.

而且那时候我真走不开，母牛要产仔，且有得忙呢。

The cleavage rate of 2-cell stage was 50%, but few embryos developed into morulas and blastocysts (2%). More than 130 embryos at 2-4-cell stage were transferred into oviduct of 13 synchronized foster rabbits and 2 mice. No fetus or implantation sites were observed in both recipients.

其2—细胞胚胎的分裂率可达50％，但发育至桑椹胚和囊胚阶段的胚胎数目大大减少，只有2％的囊胚发育率。13只受体兔共移植重构胚胎121枚，结果未发现产仔或死胎，仅看到有的兔子宫有於血状。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
