随着畜牧业生产规模的不断扩大和集约化程度的不断提高，畜牧生产中产生的氨气、硫化氢、粪臭素等恶臭气体和粪尿中的氮、磷等元素对空气、土壤和水体造成了严重的环境污染，极大地影响了人类的生存质量和身体健康。因此，充分运用生物技术，减少畜牧业对环境的污染，促进畜牧业可持续发展具有十分重要的现实意义。 相似文献

严格控制药物残留 确保动物性食品安全 总被引：4，自引：0，他引：4
近些年来。随着畜牧业的发展，为了提高产量，防治疫病的需要，人们大量使用兽药和饲料添加剂。虽然达到了增产增收和防病治病的目的，但由于在生产加工过程中违禁使用、使用不当和过度使用等原因，使药物残留对肉、蛋、奶等动物性食品的污染问题日益突出，造成了对人类健康的严重威胁和对 相似文献

在20世纪八九十年代，精益化生产管理走进国门．在冲击电子、汽车、化工等行业现场管理的同时．也对饲料企业的生产现场造成了一定影响，许多饲料企业引进了6S等现场管理方法。但一段时间后，生产现场往往又恢复了往日的模样．一场轰轰烈烈的大扫除运动在一片叹息声中宣告结束。于 相似文献

因气候变暖,无霜期变长,小蜂螨发生早、危害时间长,对养蜂业造成了极大的困扰。有的蜂友说,春繁时期就发现有小蜂螨活动,严重影响了春繁和春季生产。采取多种防治方法一直治不好。直到秋末断子,仍然有小蜂螨活动,损失重大。 相似文献

水产养殖用药常见问题与对策 总被引：2，自引：0，他引：2
在水产养殖用药物的生产、销售及使用中存在着药物选择不当、鱼用药物标签和使用说明书标注不详及事故解决机制不完善等诸多问题，给生产造成了很大损失。本文从致害鉴定、标签管理等方面提出了建议，以保护水产养殖业的健康发展。 相似文献

近年来，在畜禽养殖及肉产品生产、加工过程中，由于存在不按规范使用疫苗、兽药、添加剂等，各种疾病时有发生，生产、加工环境不卫生及操作不规范，人为添加禁用物质等问题，使人们对食用畜禽产品产生了恐慌心理，造成了畜禽产品生产秩序的混乱。本文立足于我国猪肉生产的实际，分析了我国猪肉生产中存在的问题，利用经济学理论，对我国猪肉生产中存在的问题进行了深入地探讨和分析，并探究出不安全猪肉存在的原因；同时，从我国的法律体系、管理体制、生产环节及疫病防控机制等方面分析了影响安全猪肉生产的因素，并提出了相应的政策建议。 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
