<正>现代规模养猪必须充分利用现代免疫营养调控技术,结合"抵抗应激、增强免疫、均衡营养、健康养猪"的现代养猪理念,贯彻"养重于防、防重于治、防治结合"的实践方针,才能给规模养猪生产者提供全面的营养解决方案和系统的健康管理方案,从而有效解决规模养猪过程中的重大疾病困扰。一、彻底转变疫病控制的传统观念,减少疫病控制技术上的一些误区疾病控制不是单纯的兽医问题;疫苗不是所有疫病的救世主;疫苗效力的发挥,营养、管理和环境是前提;药物不再是治疗 相似文献

目前中国现代规模养猪面临严重的疾病挑战,主要包括猪的繁殖障碍综合症、断奶仔猪多系统衰竭综合症(PMWS)、猪皮炎肾炎综合症(PDNS)、呼吸道疾病综合症(PRDC)、无名高热综合症(主要是高致病性蓝耳病引起)、免疫抑制病和营养代谢疾病等,使养猪业成为一种高风险和高投入的产业。养猪过程中存在很多应激因子,也有许多导致免疫抑制的因素包括蓝耳病毒(PRRS)、猪圆环病毒2型(PCV2)、猪瘟病毒(CSF)和伪狂犬病毒(PRV)等。免疫抑制的后果便是抗生素和疫苗的使用效果变差,猪只的免疫保护和抵抗疾病能力下降或紊乱,进一步导致继发性感染机会大幅增加,生长缓慢或停滞甚至死亡,给养猪业造成严重的经济损失。本文针对目前中国规模养猪目前的主要流行疾病,介绍大成补克博士如何利用以现代免疫营养调控为主的"优补力生物技术",结合"抵抗应激、增强免疫、均衡营养、健康养猪"的现代养猪理念,旨在给现代规模养猪生产者提供全面的营养解决方案和全面的健康管理方案,从而解决规模养猪过程中的重大疾病困扰,以期提升规模养猪企业的市场竞争力。 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
