摘要
选用1日龄AA肉仔鸡250只,随机分为5组,每组50只,即中药低剂量组、中药中剂量组、中药高剂量组、化学药物组和空白对照组,分别隔离饲养。在2周龄和4周龄时测定肠道中厌氧菌、大肠杆菌、沙门氏菌数量。结果:2周龄时,中药高剂量组鸡肠道内每克内容物中大肠杆菌数为1.82×107个,厌氧菌数为4.43×108个;化学药物组大肠杆菌数为1.62×107个,厌氧菌数为2.17×108个;4周龄时中药高剂量组大肠杆菌菌数为1.57×107个,厌氧菌数为1.94×108个;化学药物组大肠杆菌数为3.51×107个,厌氧菌数为1.16×108个。结论:中草药替代化学药物预防肉仔鸡的肠道传染病是可行的。
