[Objective] The paper was to investigate the effects of adding different levels of Shuanghuanglian propolis 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 II 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 propolis oral liquid in drinking water,respectively.[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 significantly lower than that in group I (P<0.05); the number of intestinal Lactobacillus spp.in group II and group III increased significantly (P<0.05); the number of Salmonella spp.and Escherichia coli in group III decreased significantly (P<0.05); the number of Bifidobacterium 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 microflora of broilers,and the dose of 1.0 mL/L is recommended in clinical application.
