动物微生态制剂在养殖业中的应用   总被引:7,自引:0,他引:7  
动物微生态制剂,又称为微生物饲料添加剂,是在微生态学理论的指导下,将从动物体内分离出的有益微生物经特殊工艺制成的只含活菌或者包含细菌菌体及其代谢产物的活菌制剂。使用微生态制剂的最终目的是维持动物消化道内的微生物平衡,提高动物对饲料的利用率,防治疾病,提高动物的生产能力。  相似文献

动物微生态制剂的研究概况   总被引:1,自引:0,他引:1  
动物微生态制剂指在微生态理论指导下,将从动物体内分离的有益微生物,经特殊工艺加工成的含活菌或菌体及其代谢产物的活菌制剂,又称为微生物饲料添加剂。世界上已有许多国家大量使用微生态制剂,如日本每年益生素用量在1000t以上。我国动物微生态制剂的研究起源于20世纪70年代末80年代初,90年代以后进入产业化研制、开发及大规模生产期。目前,微生态制剂已被公认为有希望取代抗生素的饲料添加剂。  相似文献

一、对微生态制剂的认识 (一)微生态制剂(Probiotics)概念1996年.Fuller和Cole定义:一种活的饲料添加剂,经过改善其宿主的肠道微生物平衡,而对宿主产生有益的影响。1991年.我国学者又提出一个较通俗的概念:饲用微生物添加剂。何明清定义微生态制剂是指在微生态理论指导下.采用有益的微生物.经培养、发酵、干燥等系列工艺制成的对人和动物有益的生物制剂或活菌制剂.称为益生菌剂或微生态制剂.俗称益生素。  相似文献

浅谈水产养殖中的微生态制剂   总被引:3,自引:0,他引:3  
微生态制剂是一种新型活菌制剂,是人们根据微生态学原理,运用优势菌群,对鱼体内正常的有益微生物菌种或菌株经过鉴别选种、大量培养、干燥等系列加工手段制成的,它具有成本低、无毒副作用、无环境污染等特点。通过微生态制剂的使用,可使鱼体内(如肠道)、鱼类的生活环境中的微生物达到菌群平衡,或人为使有益微生物成为优势种群,减少有害菌对鱼类的侵袭机会,达到防病治病的目的。  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
