當前生豬生產由過去的散養逐漸發展成集約化規模養殖
，做好規模化豬場疫病的綜合防治
，關係著養殖戶的效益。

近幾年來我國將豬瘟、豬口蹄疫、豬鏈球菌病等作為國家強製免疫性疾病後經過長期努力病情已得到了有效控製
，但夏季高熱性疫病常導致一些豬場遭受致命打擊。

發病情況　根據不同地區各養殖場的樣本檢驗發現，目前存在於規模化豬場的主要病原體包括：豬圓環病毒
、豬繁殖與呼吸綜合征病毒、豬瘟病毒等病毒以及大腸杆菌、lianqiujundengxijun。gezhuchangdefabingtedianbiaoxianweidanbingyinjiaoshao

，從而繼發其他細菌性、病毒性疾病。

疫病預防　加強飼養管理，改善飼養環境，降低環境中不良因素對動物機體的危害，提高動物本身對疫病的抵抗能力。
