Ninety one-day-old broilers were randomly divided into three groups ： group I was designed as control; groups Ⅱ and Ⅲ were added with 0.5 and 1.0 mL/L Shuanghuanglian propolis oral liquid in drinking water, respectively. Compared with group I, all tested indicators in groups Ⅱ and Ⅲ were increased at varying degrees as follows ： bursa of fabricius index increased by 5.74% （P 〈 0.05 ） and 7.66% （P 〈 0.05 ） ; thymus index increased by 1.47% （P 〉 0.05 ） and 2.06% （P 〈 0.05 ） ; spleen index increased by 5.88% （P 〉 0.05 ） and 7.84% （ P 〈 0.05 ） ; Newcastle disease virus （NDV） antibody titer increased by 11.99% （P 〈 0.05 ） and 16.94% （P 〈 0.05 ） ; IL-2 content increased by 2.71% （P 〉 0.05） and 4.52% （P 〈 0.05 ） ; IL -6 content increased by 4.04% （P 〉 0.05 ） and 7.26% （ P 〈 0.05 ）, respectively. The results showed that adding 0.5 and 1.0 mL/L Shuanghuangllan propolis oral liquid in drinking water could improve the immune function of broiler and immune effect of ND vaccine.展开更多

[ 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
