摘要
【目的】本文旨在系统性评价功能性寡糖对肉仔鸡免疫器官指数的影响。【方法】本文使用计算机检索CNKI数据库,通过纳入标准对相关文献进行筛选,对获得的13篇文献29项研究进行Meta分析。【结果】与对照组相比,添加寡糖组胸腺指数[WMD=0.243,95%CI=(0.173,0.314),P=0.000]、法氏囊指数[WMD=0.097,95%CI=(0.072,0.122),P=0.000]、脾脏指数[WMD=0.094,95%CI=(0.067,0.121),P=0.000]均极显著高于对照组。按寡糖添加剂进行的亚组分析结果表明,不同类型功能性寡糖对肉仔鸡免疫器官指数影响效果不一致,果寡糖对胸腺指数提高效果以及果胶寡糖螯合锌对法氏囊指数和脾脏指数提高效果最佳。剪补法敏感性分析结果显示,日粮中添加功能性寡糖显著提高肉仔鸡免疫器官指数的结论均较为稳健。胸腺指数和法氏囊指数相关研究不存在明显的发表偏倚,但脾脏指数相关研究存在一定的发表偏倚。【结论】日粮中添加功能性寡糖具有提高42日龄肉仔鸡免疫器官指数的作用。
【Objective】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[WMD=0.243,95%CI=(0.173,0.314),P=0.000],bursa index[WMD=0.097,95%CI=(0.072,0.122),P=0.000],spleen index[WMD=0.094,95%CI=(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 of spleen and fasciae were the best.The results of sensitivity analysis showed that adding functionaloligosaccharides to diet significantly increased the immune organ index of 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.【Conclusion】Based on the existed evidence,dietary supplementation of functional oligosaccharide could increase the immune organ index of 42-day-old broilers.
