猪气喘病防治

Prevention and Control of Swine Asthma

猪气喘病是一种慢性的肺部传染性疾病,是生猪养殖领域的一种常发病和高发病病原体为肺炎支原体。发病后,患病猪主要表现为持续性咳嗽,从鼻腔中流出清澈脓性鼻液,并引发肺脏组织出现严重的病变,造成呼吸困难,生长发育不良,饲料利用率下降。猪气喘病在养殖场中一旦传播流行,将很难清理,并会呈现周期性循环反复感染的现象,带来的经济损失不可估量。该文探讨猪气喘病的流行病学、诊断方法和防治对策。

Swine asthma is a chronic lung infectious disease disease that is a frequent and high risk agent in pig farming,mycoplasma pneumoniae.After the onset of the disease,the pigs mainly showed persistent cough,clear purulent nasal fluid from the nasal cavity,and caused serious lung tissue lesions,resulting in dyspnea,stunted growth,reduced feed utilization.Once pig asthma spreads in the farm,it will be difficult to clean up,and there will be a cyclical phenomenon of repeated infection,bringing about immeasurable economic losses.This paper deals with the epidemiology,diagnosis and control of swine asthma.
