绵羊生产

It includes determination of properties of the acid protease and lipase, application of acid enzymes to processes of bating pickling pelt and wet blue of sheepskins, analysis of activities of collagenase in acid protease and trypsin. Comparison was conducted to acid bating and common bating. Orthogonal experiments were used to determine influence of some factors in acid bating on qualities of leather. Scanning electronic microscope was used to observe separating of collage fibers.

对酸性蛋白酶、酸性脂肪酶的性能进行了测定；将其用于绵羊服装革生产的酸性软化及蓝湿皮软化中，利用正交试验法研究了酸性酶软化各因素对成革质量的影响，并与常规酶软化进行了对比；用扫描电镜观察了酸性酶软化后胶原纤维的分散情况；对酸性蛋白酶的分子量进行了测定，对比了酸性蛋白酶与胰酶中的胶原酶活力，以说明酸性酶软化与胰酶软化对胶原性质的影响。

The results have indicated that acid bating fits to bating of sheepskins especially for sheepskin's loose structure because of more alleviate action of acid enzymes, and acid bating has little loss of hide substance.

结果表明，酸性酶软化作用温和、深透，对胶原损害小，特别适合于组织结构疏松的绵羊皮生产。酶制剂用于绵羊服装革鞣前准备其它关键工序，可减少硫化物、表面活性剂等有害物质的用量，提高铬结合，减少作用时间，提高面积得率和成革质量。

It also demonstrates that using enzymes in other processes in beamhouse will result in decreasing of operation time and the dosage of hazardous materials such as sodium sulfide, surfactant etc, increasing of amount of fixed chrome in leather and raising yield of leather and qualities.

利用生物酶技术进行绵羊服装革生产时，应注意选择合适的复鞣、加脂剂，进行适当的配伍，并选择合适的加料顺序和方法，以得到最佳的坯革质量。选择合适的整理方式、涂饰材料和涂饰方法对绵羊服装革的外观和内在质量也很重要。

The manufacture techniques and quality requirements of vegetable-tanned hand-scratched grain sheepskin leather were introduced,and key points and cautionary items during making process were also discussed.

阐述了绵羊皮植鞣抓纹革制作工艺、质量要求及生产过程中各工序的技术关键和注意事项。

This study determined the existence of contagious ovine pleuropneumonia in Xinjiang and biological characteristics of pathogen isolates,exploringly established HN-PCR method for rapid detection,which can provide important science basis and technology means for fast diagnosis,molecular epidemiology,prevention and treatment of the disease.It will also has important academic value and application meaning on prevention of contagious ovine pleuropneumonia in Xinjiang.

本项研究确定了绵羊传染性胸膜肺炎在新疆的存在及分离株的主要生物学特性并探索建立了快速检测病原的半套式PCR方法，为绵羊传染性胸膜肺炎的快速诊断、分子流行病学及防治提供重要的科学依据与技术手段，对新疆地区绵羊传染性胸膜肺炎的控制具有重要的学术价值及生产应用意义。

In this review, the evidence of association between poly-morphisms of PRNP and resistance or susceptibility to scrapie and its effects on reproduction and performance traits were focused. The aim is to provide theory guidance for sheep breeding resistant to disease.

文章主要介绍了绵羊PRNP遗传多样性与痒病抗病性的关系以及PRNP遗传多样性对繁殖力和其他主要生产性能的影响等方面的研究成果，旨在为绵羊抗病育种研究提供理论参考。

And as different degrees of industry were apt to give men possessions in different proportions, so this invention of money gave them the opportunity to continue and enlarge them: for supposing an island, separate from all possible commerce with the rest of the world, wherein there were but an hundred families, but there were sheep, horses and cows, with other useful animals, wholesome fruits, and land enough for corn for a hundred thousand times as many, but nothing in the island, either because of its commonness, or perishableness, fit to supply the place of money; what reason could any one have there to enlarge his possessions beyond the use of his family, and a plentiful supply to its consumption, either in what their own industry produced, or they could barter for like perishable, useful commodities, with others?

就像不同程度的勤劳会给人们不同数量的财产，货币的发明也给予了他们机会去保存和扩大货币。想象有这么一个岛屿，与世界其它地方的贸易完全隔绝，在那里只有一百户家庭，但是有绵羊，马和奶牛，和其它一些有用的兽禽和有益健康的果实，以及足够生产十万倍谷物的土地，可是，由于这些物品不是太过普遍就是易于腐烂，岛上竟没有一样东西适合做货币；在这种情况下，那里的任何人在超过他的家庭所需，以及通过自身的劳动生产或与他人物物交换一些类似的易腐的有用的日用品之外又有什么理性去扩充他的财产呢？

Result The results showed that diet pelleting could obviously improve the stalk utilization ratio and production performance of sheep.

结果］结果表明，日粮制粒能明显地提高绵羊对玉米秸秆的利用率和绵羊的生产性能。

The research aimed to study the effects of diet pelleting on the production performance, economic benefit, stalk digestibility of sheep.

［目的］研究颗粒料对绵羊生产性能、经济效益及秸秆消化率的影响。

Nner Mongolian fine wool wethers of two years old with permanent ruminal and duodenal cannulas, divided into 4 groups of 3 at randomly, were used in this trail.

·一 试呛三：不同日粮阴阳离子水平的对绵羊生产性能及氮平衡的迈响选用12 ／q安装有永久性瘤胃窿管及十二指肠疹管的内蒙古半细毛羊渴羊，随机分成4组，每组3个重复，饲给4种不同阴阳离子水平日粮，以研究在大量饲g玉米秸秆条件下DCAB对绵羊干物质采食量（DMI人体重变化及氮平衡的形响。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
