随着我国牛养殖数量不断增加;单产水平、营养需求不断提高;规模化养殖程度逐步加大,牛群流动速度出现快且范围广的特点.加上各地饲养模式参差不齐、管理水平高低不一、动物疫病防控系统尚不健全和疾病防治措施不当等众多原因,牛病的发生特点及流行趋势表现为旧病未除,新病不断;传染病发生增多,牛源性的人畜共患病发生率明显上升,疫病危害加大;细菌混合感染、细菌耐药性及环境污染等问题日益严重;规模化牛场营养代谢病和繁殖障碍及肢蹄病会不断出现,危害增大.  相似文献

<正>近两年獭兔价格上升较快,獭兔市场行情逐渐变好。但随之出现的一些问题,诸如兔皮质量差、销售低;疾病不断、药物不断、死亡不断;越养体重越小、质量越差、遗传性疾病越多;花钱多却效益不高等。究其根源,这些都与引种不当、留种不科学有关。要做到既提高獭兔产品质量,又缩短饲养周期,在引种与留种时就必须注意以下几方面的问题。  相似文献

目前,规模化猪场细菌病常年不断发生,特别是猪群中发生各种病毒病时,往往都出现细菌病的混合感染或继发感染,导致猪群发病率与死亡率增高,造成重大经济损失。尤其是在当前猪群中免疫抑制性疾病普遍存在;病原体不断发生变异,新的血清型不断出现;滥用抗生素造成细菌耐药性增高,导致"超级细菌"的出现;加之生物安全措施不健全、  相似文献

随着人们生活水平的不断提高,经济不断增长。城镇居民对绿色食品需求量越来越高。土鸡、土鸡蛋成为人们饭桌上的抢手货。养鸡以农村散养为主,长期以来由于饲养质量差,营养水平跟不上和饲养管理粗放,疾病不断发生,生长速度过缓,以致出现"孵化得多,成活得少;养得多,育成得少;发病得多,出笼得少;死亡得多,效益少"的局面。农村散养户积极性大大降低。近年来,我们在实践中不断探索,总结了提高  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
