产仔

Duroc are more likely to be over conditioned at farrowing time.

杜洛克的体况在产仔时更容易掉膘。

Temperature also affected, to some extent, the trend of the abundance of mycetocytes following the development of aphids. The abundance of mycetocytes increased with the development from nymph to adult before larviposition in the aphid at 15℃, 20℃ and 25℃, but culminated at the 3rd instar and thereafter declined at higher temperatures (30℃ and 35℃).

温度对菌胞数量随宿主发育到产仔前的变化趋势有不同程度的影响，在较低温度（15℃、20℃和25℃）下，菌胞数量随虫体发育显著增加；但在高温（30℃和35℃）下，蚜虫体内菌胞数逐渐增加直到3龄达到最高，然后略有下降(30℃)或显著下降(35℃)。

The test group with PMSG and HCG were compared with the control group in the oestrus rate,conception rate and live farrowing rate.

试验比较了PMSG+HCG与对照组的发情率、受胎率、产仔率等繁殖性能指标。

The vector was linearized and injected into 817 fertilized eggs of mice in which coagulation factor IX gene has been knocked out. The manipulated embryos were transferred into the oviducts of 45 pseudopregnant females, from which 63 offsprings were obtained.

将其线性化后，用显微注射法注射入817只凝血因子Ⅸ基因剔除小鼠受精卵雄原核，再将它们分别回输45只假孕受体母鼠的输卵管中，共产仔69只，存活63只。

The changes in the weight, exponential, structure of the tissue, cell apoptosis in testis and epididymis and the changes in the sperm tectology in epididymis were measured on the day 8, 13, 21 and 35 of the treatment,respectively,by the method of morphological examination.

分别在热应激持续到8d、13d、21d和35d时，应用形态学观察法，研究受试鼠睾丸和附睾重量及指数、组织结构、细胞凋亡和附睾精子形态学的变化；应用免疫荧光细胞化学和蛋白质印迹分析的方法，研究睾丸和附睾组织中热休克蛋白70(HSP70)的表达；应用比色法检测睾丸和附睾组织内活性氧和丙二醛、抗氧化物酶(SOD、GSH-Px、CAT)的活力或浓度的变化；应用交配试验，检测雄鼠受精能力及其致孕雌鼠的产仔数的变化，用以揭示热应激对雄鼠生殖机能的影响。

In any case, after that litter dispersed, our vixen sited her new den this spring down close to the asphalt, where there are more houses, garbage, domestic critters, and roadkills, but another trucial zone exists where coyotes are loath to go.

在任何情况下，在被驱散的情况下产仔之后，我们的雌狐会把她在这个春天新的处身之地安置在靠近沥青的地方，那里有很多的住处，垃圾，驯服的动物，和道路。但是还有另一个暂时的而且狼群不情愿去的地方，价格至少损失一只狗相对一辆车来说。

This is an important time of your to work at attaining a good breeding and farrowing percent.

对于你获得好的育种和产仔率，这是一个非常重要的时间。

A bivariate animal model was used for estimation ofvariance components, including fixed effects of age of calving, herd-test-day, and days in milk, in addition to random additive genetic effects and permanent environmental effects.

阿二元动物模型，用于估计差额部分，包括影响产仔年龄固定的原因，畜群试验一天牛奶中，除了遗传效应随机添加剂还有永久的环境影响。

Bruce Mate: We confirmed that mating, calving and feeding all take place at the Costa Rica Dome.

布鲁斯 梅特：我们确认鲸群是在哥斯达黎加圆顶进行交配、产仔和哺育。

This thesis gave a study on the polymorphism of ob gene in erhualian, xiang pig, Large White, Duroc, Landrace, Pietran and Landrace X erhualian crossbreeds , by means of Bi-PASA.

本文采用Bi-PASA方法对二花脸、香猪、大约克、杜洛克、长白、皮特兰和苏钟1系猪七个类型，共计420头猪的DNA样进行了OB基因的分型研究，分析了各基因型之间在产仔数性状和生长性状上的差异，以及各个品种类型在该位点的多态性。

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。
