牛胃肠炎诊断及治疗

Diagnosis and Treatment of Bovine Gastroenteritis

牛胃肠是因为胃肠黏膜和深层组织出现炎症病变所引发的一种疾病,主要是因为牛的胃肠道受到强烈有毒有害物质刺激所致,大多数是因为采食品质不佳的草料,如发霉变质的干草,冷冻腐败的块根类饲料,发霉变质的玉米等。另外在养殖管理过程中,如果向牛群投喂大量有毒有害的牧草、刺激性较强的药物或者误食农药,也可以造成胃肠道黏膜出现严重损伤,从而引发胃肠炎症状。营养营养不良、长途运输造成身体抵抗能力下降,使胃肠道中的各种条件性致病菌,如大肠杆菌坏死杆菌等致病原的致病性逐渐增强,产生大量有毒有害物质,损害胃肠道黏膜的完整性,可以引发胃肠炎。在长时间的养殖管理中,不合理的药物使用方式,尤其是抗生素使用,使牛胃肠道菌群失衡,引起致病原感染。该文主要论述牛外肠炎临床症状、病理变化、诊断方法,提出相应的治疗措施。

Bovine gastro-intestine is a disease caused by inflammation of the gastrointestinal mucosa and deep tissues.It is mainly caused by the stimulation of the gastro-intestinal tract by strong toxic and harmful substances,such as mildewed hay,frozen rotten root type feed,mildewed corn and so on.In addition,in the course of breeding management,if the cattle were fed with a large number of poisonous and harmful herbage,stimulating drugs or pesticides,it could also cause serious damage to gastrointestinal mucosa,thus causing gastroenteritis symptoms.Malnutrition and long-distance transportation cause the decline of the body's resistance,which gradually increases the pathogenicity of various conditional pathogenic bacteria in the gastrointestinal tract,such as E.coli and necrobacteria,and produces a large number of toxic and harmful substances,damage the integrity of the gastrointestinal tract mucosa,can cause gastroenteritis.In the long-term breeding management,the unreasonable use of drugs,especially the use of antibiotics,so that cattle gastrointestinal flora imbalance,cause pathogenic infection.This article mainly discusses the clinical symptoms,pathological changes and diagnostic methods of bovine enteritis,and puts forward the corresponding treatment measures.
