摘要
[ Objective] The paper was to investigate the effects of adding different levels of Shuanghuanglian propelis oral liquid in drinking water on growth performance and intestinal microflora of broilers. [ 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.
