猪瘟是一个猪场疫病防控的重点,应引起重视,千万不能马虎了事。然而,这样重要的一种疫病,常常有些猪场却失败,造成巨大的经济损失,笔者现就谈谈猪瘟免疫失败的原因及对策供同行参考。1免疫程序不合理各个猪场的免疫程序各不相同,不能生搬硬套其他猪场的免疫程序或某专家推荐的现成程序,因为各个场猪只所处的环境条件不尽相同,其免疫应答反应千差万别,不注意这些因素极易造成猪瘟免疫的失败。因此,应定期对母源抗体水平进行检测, 相似文献

我国是猪肉生产大国,全国各地出现了越来越多的猪场,并且开始形成规模化。对于猪场来说,有效地防控猪只疫病是首要问题,猪只疫病尤其是烈性传染病对于猪场来说后果是非常严重的,甚至是毁灭性的,所以疫病防控就显得尤为重要。本文主要从猪场消毒和疫病防控2个方面阐述如何在猪场内控制疫病,以期对规模化养猪场的疫病控制有所帮助。 相似文献

生猪屠宰检疫猪只疫病控制、防止病害、劣质猪肉流入市场以及保护公共卫生等方面发挥着重要作用。笔者通过对生猪屠宰检疫中猪圆环病病例的调查,发现以皮炎肾病型的猪圆环病阳性率为0.0046%,并针对阳性猪场提出猪圆环病的防控建议,以降低猪圆环病给猪场造成的经济损失。 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
