摘要
为了解2022年豫南地区畜禽在养殖过程中疫病发生和流行的情况,笔者对豫南地区1 791个养猪场(户),582个养牛场(户),776个养羊场(户),1 691个养鸡场(户),111个养鸭场(户),79个养鹅场(户)进行流行病学调查。结果显示,猪病中以仔猪白痢的场群发病率最高,仔猪黄痢发病数量和死亡数量最多,占生猪死亡总数的33.73%;禽病中以大肠杆菌病的场群发病率最高,发病数量和死亡数量也最多,占家禽死亡总数的37.98%;牛羊病中以犊牛痢疾场群发病率最高,羔羊痢疾的发病数量和死亡数量最多,占牛羊病死亡总数的54.34%。根据2022年畜禽疫病流行病学调查情况与2023年季节特点,笔者对2023年豫南地区可能发生的畜禽疫病进行预警预报。
