摘要:猪气管炎是指气管黏膜表面或者深层组织出现炎症病变所引发的一种呼吸系统疾病,该病具有典型的季节性,常发于冬春季节,气候剧烈变化的时间段,任何年龄、品种的猪都可以受到该病影响,临床上主要表现为咳嗽、流鼻涕,体表温度忽高忽低,伴随干性、湿性啰音。临床上可分为急性支气管炎和慢性支气管炎。猪支气管炎的发病原因多样,病原微生物侵袭,饲养管理不当等均会造成猪支气管炎的流行。该文通过一起猪支气管炎的诊治,探讨了猪支气管炎的诊断与防治过程。

Abstract:Porcine bronchitis is a respiratory disease caused by inflammatory lesions in the tracheal mucosa or deep tissues,which is typically seasonal,often occurring in winter and spring,when the climate changes dramatically,and pigs of any age and breed can be affected by the disease. Clinically,it can be divided into acute bronchitis and chronic bronchitis. The pathogenesis of bronchitis in pigs is diverse,and the prevalence of bronchitis in pigs can be caused by pathogenic microbial infestation and improper feeding management. This paper discusses the diagnosis and prevention process of bronchitis in pigs through the diagnosis and treatment of a case of bronchitis in pigs,hoping to be helpful to the majority of colleagues.
Keywords:porcine bbronchitis,diagnosis,prevention
0引言
猪支气管炎是由多种原因引发的一种气管黏膜表面或者深层出现炎症的病变,临床上以咳嗽、鼻涕、温度忽高忽低为主要特征。根据疾病发病的快慢,主要划分为急性型和慢性型,是生猪养殖过程中的常发病和高发病。当前,由于很多养殖场管理不当,加之气候变化,造成支气管炎时有发生。30日龄内的仔猪、断奶仔猪和4月龄内的猪,对该病的易感性较强,气候发生变化或者气候寒冷时容易高发。猪支气管炎流行会严重威胁到猪的正常生长发育,甚至会危及到动物的生命安全,造成大批量的猪死亡,带来的经济损失不可估量。
1病例探讨
2020年1月下旬,某规模化生猪养殖场出现一种传染性疾病,临床上以呼吸道症状为主,患病猪表现为咳嗽、气喘,体温升高到39 ℃,最高升高到41 ℃。先是在个别猪,尤其是断奶仔猪体中发生,个别患病猪出现偶尔咳嗽、流鼻涕的症状,采食量稍有减少,早晨咳嗽症状比较明显,有时咳出痰液,在发病4~5 d后,7头猪出现咳嗽症状。……
