Abstract:

Abstract：The objective of this experiment was to study the effects of dietary synbiotics on immune functiou of meat-type quails．One hundred and twenty one-day-old meat-type quails were allocated to control group and symbiotics group. 60 meat-quails in each group. Control group fed with basal diet，the other was experimental group fed with basal diet supplemented 0.05% synbiotics. The experiment period is 35 days. The results showed that synbiotics increased significantly immune organ indexes, antibody level against ND and E-rosette formation rate, significant difference in 28～35-day-old. Supplementation of synbiotics decreased significantly the of Escherichia coli and Salmonella (P<0.05), but increased obviously the numbers of Lactobacillus in the jejunum of meat quails(P<0.05).
