犊牛呼吸道疾病诊断与治疗

Diagnosis and Treatment of Respiratory Diseases in Calves

呼吸道疾病是犊牛养殖期间极易出现的一类传染性疾病,该种疾病的发病原因十分复杂,致病原种类多样。犊牛出生后,由于外界温度忽高忽低,应激因素较多,再加上犊牛身体抵抗能力相对较差,很容易受到多种病原的入侵。通常犊牛呼吸道疾病的发生流行主要与养殖管理不当、各种病原微生物入侵相关。如果2种以上病原混合感染,会加重临床症状,患病牛发病周期逐渐缩短,致死率显著升高。该文探讨犊牛呼吸道疾病的发病原因、临床症状、诊断和治疗措施。

Respiratory disease is a kind of infectious disease that can easily occur during calf breeding.After the birth of calves,there are many stress factors due to the fluctuation of external temperature and the relatively poor resistance ability of calves,so it is easy to be invaded by a variety of pathogens.Generally,the occurrence and prevalence of calf respiratory diseases are mainly related to improper breeding management and invasion of various pathogenic microorganisms.If more than two pathogens are mixed,the clinical symptoms will be aggravated,the onset period of the infected cattle will be shortened gradually,and the fatality rate will be significantly increased.To investigate the causes,clinical symptoms,diagnosis and treatment of respiratory diseases in calves.
