【摘要】 选择健康的1日龄爱拔益加(AA)肉公鸡555只,按体重随机分成5个组(1～5组),5组饲喂基础日粮(对照组)、1～4组为试验组,试验组在基础日粮中分别添加0.15%饲用金霉素、0.15%中草药与芽孢杆菌益生素、0.15%中草药与乳酸杆菌益生素、0.15%中草药与芽孢杆菌、乳酸杆菌益生素。结果表明:肠道菌群情况,2、3、4组肠道内大肠杆菌对数值极显著低于1组和对照组(P<0.01);粪样菌群情况,2、3、4组粪样内大肠杆菌对数值极显著低于1组和对照组(P<0.01)。更多还原

【Abstract】 To study the effect of probiotics on intestinal germ and immunity apparatus exponential of chickens,555 healthy Arbor Acres roosters of one-day age were divided into five groups.The Group 1 was fed on basal diet(Control Group),the Groups 1~4(Test Groups)were fed on additive of 0.15% arueomycin,probiotics composed of 0.15% Chinese herbal medicine and sprout bacillus,probiotics composed of 0.15% Chinese herbal medicine and lactobacillus,probiotics composed of 0.15% Chinese herbal medicine,sprout bacillus and lactobacillus based on,basal feed.The result indicated:in the respect of intestinal germ,the logarithm of coliform in Group 2,3,4 were very obvious lower than Group 1 and Control Group(P<0.01);as for the respect of mucky germ,the logarithm of coliform in Group 2,3,4 were very obviously lower than aureomycin group and control group(P<0.01).Probiotics could obviously promote the growth of broiler’s immunity apparatus and immunity apparatus exponential.更多还原
