猪传染性胃肠炎病因及防治

Causes and Control of Transmissible Gastroenteritis of Pigs

猪传染性肠胃炎在养猪密集区的发生率较高,仔猪发病后死亡率也相对较高。这间接说明养猪密度对于猪传染性肠胃炎的发生有着较大的影响。猪传染性肠胃炎的病因相对复杂。在生猪养殖管理中,猪传染性肠胃炎往往是多种病因综合作用的结果。包括猪机体对外界抵抗力低、传染源复杂、传播途径多、病毒生命力强、猪排毒时间长、易感动物多、易受季节性影响等的原因,而养殖密度高或生猪养猪密集区便于病毒传播扩散,加剧猪传染性肠胃炎的流行及猪健康性的影响。该文基于猪传染性肠胃炎的复杂病因,探讨猪传染性肠胃炎的治疗。

Transmissible gastroenteritis of pigs occurs at a high rate in pig-intensive areas,and the mortality of piglets was relatively high.This suggests that the density of pigs has a great impact on the occurrence of transmissible gastroenteritis in pigs.The etiology of transmissible gastroenteritis in swine is relatively complex.In the management of pig breeding,transmissible gastroenteritis is often the result of a combination of multiple causes.It includes the reasons of low resistance to the outside world,complicated source of infection,many ways of transmission,strong vitality of virus,long time of virus elimination,susceptible animals,seasonal influence and so on,however,the high density of pig breeding or the dense area of pig breeding facilitate the spread of the virus,which aggravates the epidemic of transmissible gastroenteritis and the health effects of pigs.Based on the complex etiology of transmissible gastroenteritis in swine,this paper discusses the treatment of transmissible gastroenteritis in swine.
