规模化养猪场疫病防控新措施

在当今的规模化养猪生产中,疫病造成的损失较大,直接导致了许多农户和规模猪场的猪只大量发病和死亡,造成了一定的经济损失。如何制定和实施一系列的疫病防控措施以确保猪场安全生产,是业内人士亟须认真探讨和解决的问题。     

规模猪场药物保健存在的问题与对策

当前多种因素导致涪陵区规模养猪场疫病日趋复杂,疫病给猪场业主造成较大的经济损失,不利于涪陵区养猪业的持续、快续、健康发展。涪陵规模养猪场疫病防控除了要做好疫苗免疫预防,科学饲养管理等综合措施外,还应根据猪只的不同生长阶段疫病发生的特点与流行规律,搞好猪     

规模猪场疫病防控体系建设的体会

人们对肉制品的大量需求促使我国的养殖业飞速发展,规模猪场的建立在为养殖户带来巨大经济利益的同时,也带来了严重的疫病危机。疫病的爆发会影响猪只的健康,甚至引起猪只的不孕不育和死亡,所以防控疫病是规模猪场日常工作的重点。本文将论述如何建设规模猪场的疫病防控体系,以降低疫病的发生率,保障猪只的健康成长。     

猪场免疫猪发生猪瘟的原因与对策

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,     

规模化养猪场的消毒与疫病防控

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。     

对屠宰检疫中猪圆环病毒病流行的调查及防控建议

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。     

小型猪场疫病防控工作中的常见问题及优化措施分析

随着我国经济水平和科技水平的不断提高,国家加大了对生猪养殖的支持力度,此种情况既推动了我国生猪养殖行业的发展,也使生猪市场的竞争愈发激烈。在此种情况下,小型猪场场主想要在市场中站稳脚跟,就必须做好猪场疫病的防控工作,但由于很多小型猪场场主缺乏此方面知识,从而导致疫病防控不到位,进而造成经济损失。     

冬季猪场的饲养管理要点

冬季气温低,猪只抵抗力下降,若猪场不加强饲养管理,容易造成疫病的流行,带来巨大的经济损失。为了保证猪场生产正常经营,应从以下几方面着手加强管理,使猪群安全过冬。     

一例疑似仔猪流行性腹泻的诊断与防控

猪流行性腹泻是由猪流行性腹泻病毒感染所引起的一种传染性疫病,给我国养猪业造成巨大经济损失。湖南省益阳地区某规模化猪场暴发疑似猪流行性腹泻,通过对该猪场进行流行病学调查、临床症状和病理变化观察和实验室RT-PCR技术病原学检测,最终确定该猪场发生猪流行性腹泻;通过对该场猪群采取紧急处理措施使疫情得到有效的控制。笔者将诊断与防控过程进行详细记录,以期为该病的防控提供资料参考。     

规模猪场生物安全防控体系的建立要点

我国是世界上最大的生猪生产国和消费国,但是近年来疫病暴发给我国养殖业造成了巨大的经济损失。同时伴随着规模化养殖程度的提升,动物一旦感染疫病,极易导致疫病扩散,造成严重经济损失。由此可见,在猪规模化养殖中,疫病防控十分重要。然而,猪场生物安全体系对防止病毒传播扩散、提高猪生产性能具有突出优势。本文旨在探讨猪场生猪安全体系的建立要点,从猪场内外两个方面为猪场管理者提供一些建设性的对策和措施。     

Disease and destiny-mystery and mastery

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.     

Foot and mouth disease and bluetongue: differences and similarities

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.
