Abstract

In order to systematically evaluate the effect of functional oligosaccharides on immune organ index in broilers. Method: CNKI database was searched by computer, and the related literature was screened by the inclusion standard. screened relevant literatures through inclusion criteria, and Meta analyzed 29 studies of 13 literatures obtained. Result: Compared with the control group, the thymus index of the oligosaccharide group was increased [WAIL/= 0.243,95% CI = (0.173,0.314), P =0 .000], bursa index[WMD =0.097,95% C/= (0.072,0.122), P =0 .000], spleen index [WM D= 0.094,95% a= (0.067,0.121), P = 0.000] were significantly higher than those of the control group. The results of subgroup analysis based on oligosaccharide additives showed that the effects of different types of functional oligosaccharides on immune organ index of broilers were not consistent and the effects of fruit oligosaccharides on thymus index and pectin oligosaccharides and zinc coordient on the index d spleen and fasciae were the best. The results of sensitivity analysis showed that adding fimetionaloligosaccharides to diet significantly increased the immune organ index d broilers. There was no significant publication bias in the studies on thymus index and bursa index, but there was some publication bias in the studies on spleen index.
