【摘要】：猪繁殖与呼吸综合征和猪圆环病毒病是目前养猪业广泛存在且危害较大的疾病,严重影响了种猪的繁殖性能和仔猪的生长性能,多表现为地方性流行和持续性感染,是其他猪病多发和频发的主要原因。2016年5月,湖北省某规模化猪场内育肥前期猪只出现以呼吸困难、高热、皮肤出现不规则丘疹、渐行性消瘦等临床症状的急性传染病,造成猪只生长发育受阻、饲料转化率降低。根据临床症状,结合流行病学、临床剖检观察、实验室诊断等方法,最终确诊其为猪繁殖与呼吸综合征与猪圆环病毒2型的混合感染引起,同时对检测数据进行分析并采取相应措施,有效减缓了疾病的流行与蔓延。研究通过对该场疾病发生的原因及防控措施进行分析,以期为当前养殖场该类疾病的临床防控提供参考。
[Abstract]:Porcine reproductive and respiratory syndrome (PRRS) and porcine circovirus disease are widespread and harmful diseases in the pig industry at present, which seriously affect the reproductive performance and growth performance of piglets, most of which are endemic and persistent infections. In May 2016, early fattening pigs in a large-scale pig farm in Hubei Province developed an acute infectious disease with clinical symptoms such as dyspnea, high fever, irregular papules on the skin, and gradual emaciation, etc. The growth and development of pigs were blocked and feed conversion rate was decreased. According to the clinical symptoms, combined with epidemiology, clinical examination, laboratory diagnosis and other methods, the final diagnosis of porcine reproductive and respiratory syndrome and porcine circovirus 2 mixed infection, At the same time, the detection data were analyzed and the corresponding measures were taken to effectively reduce the prevalence and spread of the disease. The causes of the disease and its prevention and control measures were analyzed in order to provide a reference for the clinical prevention and control of this kind of disease in the current farm.
