Abstract: Effects of Ligustrum Lucidum (LL), Schisandra Chinensis (SC), mannanoligosaccharides(MOS) and flavomycin on growth performance and immunity of broilers were studied. 180 broilers of 1-day old were randomly assigned to six groups. The blank was provided with basal diet, the antibiotic group was provided with basal diet with addition of 5mg/kg flavomycin. Other trial groups were provided with basal diet plus 1%LL, 1%SC, 1%LL+MOS, 1%SC+MOS. The broilers were fed their respective diets from 1day to 56 days old. The results showed that SC+MOS can significant improve performance of broilers in middle and later period. LL increased antibody level significantly. Lymphocyte proliferative responses to ConA were greater (P＜0.05) in all of trial groups. Chinese herb additive can improve growth performance and immunization of broilers.
