中华人民共和国国民经济和社会发展第十个五年计划纲要指出：农业产业化是推进农业现代化的重要途径，鼓励采取公司加农户，订单农业等多种形式，大力推进农业产业化经营。支持农业加工企业、销售企业和科研单位带动农户进人市场与农户形成利益共享、风险共担的经营机制。采取财政、税收、信贷等方面的优惠政策，扶持一批重点龙头企业加快发展。这就意味着养禽生产中每一种新理论、新技术的实施，均可通过大集团的示范作用迅速传递到养殖户。 相似文献

1提出畜禽种源产业化的背景畜禽种源产业化是畜牧育种场的扩展和升华,是畜牧业现代化进程中的必然趋势。以肉鸡生产为例,约在10年前(1995年),世界上肉鸡育种企业,已由过去的百余家,逐渐集中整合到仅有10余家,近10年来基本上被三四家育种企业控制,如德国的罗曼、美国的AA、法国的ISA等。肉鸡育种企业的集中和整合体现了联合育种的魅力,也是肉鸡种源产业化的结果,其作用是明显的。目前肉鸡42d可以达到2.2kg,饲料利用率1.8:1,成活率达96%,我国肉鸡生产技术水平基本达到世界发达国家水平,年产禽肉1383万t。肉鸡生产发展快,技术水平高,与肉鸡种… 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
