中药在肉鸡无公害生产中的应用研究

将4.4万只同龄的艾维茵肉仔鸡平均分为4栋进行试验,其中中药实验组2栋,化药对照组2栋,地面常规饲养,使用由北京锦绣大地风华兽药有限公司按GMP标准生产的灭呼散、肠菌清纯中药添加剂.试验结果表明中药添加剂组与化药组相比较,可提高肉鸡的生产性能及经济效益,发病率、死亡率下降了55.94%、生产成本降低了0.19元/kg,经济效益提高了78.31%;中药能显著调节肉鸡肠道的微生态平衡,降低有害菌大肠杆菌的数量(P＜0.01),增加有益菌乳杆菌的数量(P＜0.01),并可在一定程度上增加双歧杆菌的数量;对使用中药后胴体及组织中农药、抗生素、重金属残留的监测表明,中药作为肉鸡生产中的药物添加剂可满足无公害养殖标准.
