[ Method] Ninety one-day-old broilers were randomly divided into three groups (group I, group 1I and group III): group I was the control group, and groups II and III were added with 0.5 and 1.0 mL/L Shuanghuanglian prepolis oral liquid in drinking water, respec- tively. [ Result] Compared with broilers in group I, the average daily gains of broilers in group II and group III increased significantly ( P 〈 0.05 ) ; the feed gain ratio of broilers in group III was significandy lower than that in group I ( P 〈 0.05 ) ; the number of intestinal LactobaciUus spp. in group II and group III in- creased significantly ( P 〈 0.05 ) ; the number of Salmonella spp. and Escherichia coli in group lII decreased significantly ( P 〈 0.05 ) ; the number of Bgrdobacterium spp. increased significantly ( P 〈 0.05 ). [ Conclusion] Adding 0.5 and 1.0 mL/L Shuanghuanglian propolis oral liquid in drinking water could improve growth performance and intestinal micreflora of broilers, and the dose of 1.0 mL/L is recommended in clinical application.展开更多
