肉鸡“过料病”是一种近几年流行于30日龄~40日龄商品肉鸡群的一种疾病,又称肠毒综合征,无论是地面平养还是网上平养的商品肉鸡都普遍存在,每年6月份、7月份、8月份尤为多发。该病是一种新的对肉鸡生产影响比较大且不明确切原因的传染病,以腹泻、粪便中含有未消化的饲料、采食量下降、增重缓慢、脱水等为特征,是由多种病因共同作用导致的一种综合征。

  临床症状鸡群精神状态尚好,采食量下降,增重减慢或体重下降,但生长缓慢、鸡冠苍白,部分病鸡拉白色条状或黏液状粪便,粪中有未消化的饲料,粪便颜色浅黄色、黄白色、鱼肠子样或胡萝卜样,个别鸡精神沉郁,缩头,头部震颤,来回乱跑,易惊叫,然后瘫痪。患病鸡群呈零星死亡,几乎每天都有残鸡出现。黎明前猝死明显增多或先兴奋不安后瘫软,衰竭死亡。

  剖检变化病鸡头部有积液,个别病鸡的胸腺发红,十二指肠肿胀,肠壁增厚,用手触摸感觉肠壁非常硬,肠道内无饲料,肠黏膜大量脱落,个别肠段有泡沫样物质和西红柿样粪便,同时肠壁外翻,肠黏膜粗糙,并有脓性分泌物覆盖,胆囊变小、呈淡黄色,看上去好似无胆囊现象。

  发病机理及危害此病是由鸡球虫、一些病毒和细菌混合感染引起的。鸡肠道发炎、肿胀,肠壁增厚,大量上皮细胞分解脱落,导致肠道分泌和吸收功能下降,从而使部分鸡出现营养缺乏、饲料转化率降低、生长速度减缓等症状。肠道内环境恶性改变,电解质大量流失,出现生理生化障碍,特别是钾离子大量流失,导致心脏兴奋性过度增强,肉鸡猝死症明显增多。此外,鸡的上皮细胞分解脱落后产生的有毒物质蓄积在肠道中,引起自体中毒,从而使鸡兴奋不安、尖叫、瘫痪而衰竭死亡。同时由于球虫和细菌大量繁殖,鸡的肠黏膜细胞遭到破坏,导致其消化不良,对各种营养物质吸收发生障碍。

参考方案:泻痢快克400斤水、过料佳400斤水混合饮水连用3-5天。或者是安普肠毒200斤水连用3-5天。
