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
