一江苏省畜禽种质资源状况
1畜禽品种资源丰富
江苏省畜禽遗传资源丰富,以家禽和猪为主,1987年有20个品种、27个类型被列入《江苏省家畜家禽品种志》,2006年有10个品种、11个类型被列入《国家畜禽遗传资源保护名录》,2009年有29个畜禽遗传资源列入《江苏省畜禽遗传资源保护名录》. 相似文献

随着科技和现代生物技术的迅猛发展,国际竞争会越来越激烈.包括畜禽在内的生物遗传资源已成为一个国家可持续发展的重要战略资源,资源的拥有国对该资源具有国家主权.国际社会对生物资源也十分重视,有关生物遗传资源的许多国际公约、条约等法律法规相继签署生效,促进了全球畜禽遗传资源的管理、保存和利用.本文对联合国(UN)、世界贸易组织(WTO)以及世界知识产权组织(WIPO)等国际组织相关的畜禽遗传资源管理方面的法律法规进行了研究,通过分析各项法律法规的宗旨、目标、应用条件和适用范围以及国际立法新的方向,为更有效地保护我国畜禽遗传资源,以及进行全面管理、利用和国际交流提供法律方面的参考. 相似文献

对青海省地方畜禽遗传资源现状进行了调查。结果表明,青海省地方畜禽遗传资源与1981年调查相比较,普遍存在数量减少、生产性能下降、分布范围缩小等问题。探讨了影响青海省地方畜禽遗传资源变动的原因,并提出保护青海省地方畜禽遗传资源的建议和对策。 相似文献

When early people made their appearance, zoonotic infectious diseases were already waiting, but epidemic diseases did not appear in human history until people began to live in large numbers under conditions of close contact, mainly during the last 10,000 years. Disease has decimated urban populations, conquered armies, and disrupted society. The focus here is on (1) the plague of Athens and the Black Death; (2) smallpox, influenza, and rabies; (3) avian influenza prion diseases, and foot & mouth disease; and (4) emerging and re-emerging diseases. All have veterinary public health associations. In Athens, Greece, in 430 BC, when the Spartans ravaged the countryside, hordes crowded into Athens so that orderly movements, space in which to live, and adequate supplies of food became impossible. Crowding of any population fosters disease transmission; chaos and disorder enhance it all the more. Out of northern Egypt came a terrible plague from across the Mediterranean Sea. The identity of the plague of Athens remains unsure, but the well-considered conclusion is Rift Valley Fever, a mosquito borne, viral zoonosis. The Black Death, also called the Plague, raged in Asia for centuries. In 1347, the Black Death was brought by a ship out of Asia to Sicily. The scenes of devastation were repeated throughout Europe, with 90% or more of the people dying in city after city. Influenza, too, has been a cause of periodic human epidemics, but the great pandemic of influenza occurred in the last months of World War I. In the years of highest occurrence, more than half the world's population became clinically infected. If veterinary public health had been born earlier, it could have led to elucidating the epidemiology of influenza and the plagues of Athens, Europe, and Asia. In turn, smallpox had also caused continual tragedy. In 1796, Edward Jenner began to harvest pustules of cowpox from children or infected cows and inject them into susceptible children. In 1980, the World Health Organization declared that smallpox had been eliminated from the world. Rabies, though, still strikes terror. A number of animal diseases, broadly termed emerging and re-emerging diseases, need surveillance because they have the potential to impact human health. From late in 2003 to 2007, the highly pathogenic H5N1 influenza virus in poultry infected at least 121 people and caused 62 deaths in four countries. The prion diseases, too, all have very high numbers in concentrated contacts. To control these diseases, veterinary public health is essential, with diagnosis, epidemiological surveillance, clinical manifestations, and prevention as primary measures. 相似文献

On 26th of july 2007 a new case of bluetongue was notified in the Netherlands and on 2nd of august 2007 foot-and-mouth disease was diagnosed in Surrey, England, which raised the threat of having both infections simultaniously in one area. Bluetongue and foot-and-mouth disease have a different pathogenesis, but symptoms may resemble each other at a later stage of infection. The pathogenesis and possible clinical symptoms of both infections are discussed and illustrated with pictures. 相似文献

近几年,世界饲用添加剂市场增长较快,预计今后将进一步增长,据世界粮农组织(FAO)首领会议的倡议,到2015年,将使世界营养不良的人口削减一半,其间,肉制品将会以每年2%的速度增长,特别是加快猪肉和禽肉增长。这将促进世界添加剂,尤其是蛋氨酸和赖氨酸需求量的增加。 相似文献
