一例慢性猪回肠炎诊治及体会

Diagnosis,Treatment and Experience of a Case of Chronic Porcine Ileitis

猪慢性回肠炎又被称为增生性肠炎,是以增生性出血性肠炎、小肠腺瘤病变、回肠出现炎症坏死性肠炎为主要特征的一类慢性传染性疾病,主要是由胞内劳森菌感染引发,属于接触性传染性疾病。慢性回肠炎造成的死亡率相对较低,发病周期相对较长,主要以回肠和结肠隐窝内未成熟的肠细胞发生腺瘤样的增生为主要特征,主要表现为保育猪生长育肥中出现不同程度的出血性、顽固性或者间歇性的腹泻为主要特征,大多数患病猪表现为不能正常生长,养殖周期变长,饲料利用率显著下降,对养殖场带来严重的经济损失。该文探讨了慢性猪回肠炎流行特点、临床症状和诊断方法,提出了相应的防治措施。

Porcine chronic ileitis,also known as proliferative enteritis,is a type of chronic infectious disease characterized by proliferative hemorrhagic enteritis,small bowel adenoma lesions,and ileal inflammation and necrotizing enteritis.It is mainly caused by Lawsonia intracellularis Caused by infection,it is a contagious disease.The mortality caused by chronic ileitis is relatively low,and the onset cycle is relatively long.It is mainly characterized by adenoma-like proliferation of immature intestinal cells in the ileum and colonic crypts,which are mainly manifested in nursery pigs,growth and fattening Different degrees of hemorrhagic,intractable or intermittent diarrhea are the main characteristics.Most of the sick pigs show abnormal growth,the breeding cycle becomes longer,and the feed utilization rate decreases significantly,which will bring serious economic losses to the breeding farm.In this study,the epidemic characteristics,clinical symptoms and diagnosis methods of chronic porcine ileitis were explored in combination with the disease cases in a farm,and the corresponding prevention and treatment measures were put forward.
