肉鸡复合型肠道炎症发病原因

Causes of Complex Intestinal Inflammation in Broilers

在很多集约化规模化肉鸡养殖场中普遍存在腹泻,粪便中夹杂很多没有消化饲料,采食量逐渐下降,生长发育迟缓,或者体重严重减轻,机体严重脱水,饲料报酬率下降为主要特征的传染性疾病。该类疾病在肉鸡养殖场具有很高的发病率,虽然造成的死亡率不高,但是会面临较大的经济损失。大量实践表明肉鸡复合型肠道炎症并不是由单一的肠道球虫感染引发,而是由多种病原相互制约引发的一种综合性传染性疾病,临床上又被称为肉鸡肠毒综合症。该文主要论述肉鸡复合型肠道炎症的发病原因、流行特点、临床症状、病理变化,并结合实际病例探讨该种疾病的综合防控措施。

Diarrhea is common in many intensive and large-scale broiler farms,and there is a lot of undigested feed in the feces.The feed intake gradually decreases,the growth and development are slow,or the body weight is severely reduced and the body is severely dehydrated,feed rate decline as the main feature of the infectious disease.This disease has a high incidence in broiler farms,although the mortality rate is not high,but it will face greater economic losses.A great deal of practice has shown that multiple intestinal inflammation in broiler chickens is not caused by a single infection of intestinal coccidiosis,but by a variety of pathogens that interact to cause a complex infectious disease,also known clinically as enterotoxigenic syndrome in broiler chickens.This paper mainly discusses the pathogeny,epidemic characteristics,clinical symptoms and pathological changes of compound intestinal inflammation in Broilers,and discusses the comprehensive prevention and control measures of this disease.
