西藏牦牛大肠杆菌病流行特点与防治

Epidemiological Characteristics and Control of Colibacillosis in Yaks in Tibet

牦牛分布在高海拔地区,适应能力相对较强,能在严寒的高海拔地区繁殖生长,但随着现代化畜牧养殖业的不断向前发展,养殖密度增加背景下传染性疾病发生流行率逐渐升高,大肠杆菌病已经成为牦牛养殖领域危害较为严重的细菌性疾病之一,由于引起该种疾病的临床特征复杂,短时间能造成大批量牛发病和死亡,造成的经济损失相对较大,需要加强对该种疾病临床症状的有效分析,并构建针对性的防控方案。

Yaks are distributed in high altitude areas with relatively strong adaptability and can breed and grow in cold high altitude areas.However,with the continuous development of modern animal husbandry industry,the prevalence rate of infectious diseases is gradually increasing under the background of increasing breeding density.Colibacillosis has become one of the more serious bacterial diseases in yak breeding field.Due to the complex clinical characteristics of this disease,it can cause a large number of cattle morbidity and death in a short time,resulting in relatively large economic losses.Therefore,it is necessary to strengthen the effective analysis of the clinical symptoms of this disease and construct targeted prevention and control programs.
