绵羊

Four sheep lines, HU-Yang, Chinese M erino monotocous, Chinese Merino multiparous for wool production and Chinese Merino multiparous for mutton production, were used in this study. Litter sizes were recorded for each ewe in the four lines. Primers for BMP15 and BMPR-IB gene were designed from database sheep sequence and polymorphisms were detected by PCR-RFLP method.

以绵羊BMP15基因和BMPR-IB基因为候选基因，以湖羊、中国美利奴单胎品系、中国美利奴肉用和毛用多胎品系为研究对象，采用PCR-RFLP方法对候选基因进行单核苷酸多态性位点检测和基因型分析，同时研究基因对绵羊产羔数的影响。

The best condition and viable technique route of ovine oocytes cryopreservation could be established through this study.

本研究以地方绵羊品种为研究对象，利用屠宰场废弃的绵羊卵巢获取卵母细胞，进行体外成熟培养和冷冻保存研究。

The paper systematically studied the effect of time of maturation in vitro, duration of 6-DMAP treatment and culture medium system on development of parthenogenetic ovine embryos.

系统地研究了绵羊卵母细胞成熟培养时间、6-DMAP激活时间以及改进的培养液对绵羊卵母细胞孤雌发育的影响。

Genetic polymorphism and aggregation of seven sheep populations, including three breeding sheep populations (breeding F1, F2 and Bamei mutton sheep), three introduced mutton sheep breeds (Texel, Dorset and German Merino sheep) and one local female parent population, were assessed using 10 microsatellite markers.

方法］利用10个微卫星标记对3个选育绵羊群体（选育级进1代、级进2代、巴美肉羊），3个引进肉羊品种（德克塞尔、无角道塞特、德国美利奴）和1个当地母本群体进行微卫星标记鉴定，分析这7个绵羊群体的多态性和遗传聚集性。

Researches on the mechanism and factors of sheep prolificacy are helpful to improve sheep reproduction and increase economic efficiency.

掌握绵羊多胎性机理和影响多胎性的因素对于提高绵羊繁殖率和经济效益具有重要意义。

Furthermore, the genetic relationship between the polymorphism of Prolactin and the prolificacy of Small Tail Han Sheep was explained.

结果表明： 5个绵羊品种在引物2的扩增产物中均存在单核苷酸多态性，其中只有多赛特羊未检测出DD型，而其余4个绵羊品种均检测出CC、CD和DD型。

Thus, further research was needed to discuss whicn kind of blood protein loci can be used as genetic marker of sheep prolificacy to discover the relationship between sheep prolific traits and major effect genes.

因此，关于有些血液蛋白位点可作为绵羊多胎性的遗传标记物，还需要深入研究，以更有效地揭示绵羊多胎性与有关主效基因的关系。

Experiment 2: To choose the appropriate dosage of tannins for the diets in sheep, three High Mountain Fine-wool wethers fitted with permanent rumen fistula were used and the 3 ×3 Latin square design were adopted to study the effects of tannins in Sainfoin on protein protection of the diets, measured items included the rumen metabolic parameters, the appatent digestion of all nutrients and the appatent retention of N in sheep.

试验二：选用3 只安装有永久性瘤胃瘘管的高山细毛羊羯羊，采用3×3 无重复拉丁方试验设计，研究红豆草中单宁对饲粮蛋白质保护的效果，测定项目有绵羊瘤胃代谢参数和饲粮各种养分的消化率与氮存留率，以期初步筛选出绵羊饲粮中适宜的单宁用量，为提高蛋白质饲料的有效利用提供依据。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
