小肠球虫的感染是本病的主要原因之一。小肠球虫主要寄生于肠粘膜上皮细胞中,当其大量生长繁殖时,必然导致肠粘膜增厚,水肿,严重脱落及出血等病变,则几乎使饲料不能被完全消化吸收,同时对水分的吸收也明显减少,尽管鸡大量饮水,也会引起脱水现象,所以发病鸡群所排的粪便就很稀薄且不成形,内含有没有被消化的饲料。
2、细菌感染
细菌能引起肠炎,也是肉鸡肠毒综合症的病因之一:如沙门氏菌、产气夹膜梭菌等,通过刺激破坏肠道黏膜,同时引起炎症使肠蠕动速度加快,消化液排泄过多,饲料通过消化道的时间缩短,导致消化不良。
3、病毒感染
病毒也是引起肠毒综合症的诱因之一;如呼肠弧病毒引起肠炎,损害肠道的吸收功能。
4、肠道内的酸碱平衡失调
由于季节、饲料、病原微生物等原因引起肠道菌群失调,产生大量乳酸,使肠道内PH值严重降低,肠道内环境发生改变,有益菌减少有害菌大量繁殖,又由于此时肠道处于厌氧环境,魏氏梭菌、肠梭菌等厌氧菌会大量繁殖,有害菌与球虫相互协调而加强了致病性。这样就会造成有益菌减少,而有害菌大量生长繁殖,特别是大肠杆菌、沙门氏菌能加重致病性。菌群所分泌的毒素增多,刺激肠道粘膜使肠蠕动加快,消化液排出增多,饲料通过肠道的时间缩短,消化不良,未消化的饲料随同脱落的粘膜一起排出体外,形成特征性的西红柿样或鱼肠样粪便。
5、电解质大量流失
由于球虫和有害菌大量生长繁殖导致消化不良和肠道吸收障碍,使电解质吸收减少,同时,由于大量的肠粘膜细胞迅速破裂崩解,使电解质大量流失,出现生理生化障碍,特别是钾离子的大量流失,会导致心脏的兴奋性过度增强,这也是肉鸡猝死症明显增多的主要原因之一。
6、自体中毒
在发病的过程中,大量的肠道上皮细胞破裂,在细菌的作用下,发生腐败分解,以及脱落的肠粘膜、死亡的虫体等在体内发酵分解产生大量有毒物质,同时,肠道内异常菌群分泌的毒素均会被机体吸收后发生自体中毒,出现兴奋不安、尖叫、瘫痪而衰竭死亡等症状。
7、饲料因素
饲料中大量的能量、蛋白质和部分维生素能促进细菌与球虫的大量繁殖,加重症状。所以营养越丰富,发病率就越高,症状就越严重。而饲喂品质较低的饲料相对发病较低。另外霉变饲料也能加重病。
8、药物中毒
长期用药,使药物对肠道粘膜造成损伤,引发肠炎。
防治措施:
1、加强饲养管理,勤换垫料,减低饲养密度,减少各种应激因素的刺激和防止并发症的发生。
2、保持鸡舍的清洁卫生,特别是饲槽、饮水器要定期消毒。保持鸡舍内通风良好,空气新鲜。光照强度、时间、温度、湿度,应符合科学管理的技术要求。
3、饲料:防止饲料发霉,禁止使用霉变饲料。科学的添加饲料蛋白和维生素。
4、合理运用药物预防和治疗,给予适量的金维他等营养产品,有助于鸡的生长发育,增强抗病力。
