Intestinal micro-Biological itself by the host of gene, diet, age and environment and factors of influence. However intestinal microbial of change and Host Age Between the relationship still have many unknown. This study respectively collection bar-headed goose (Anser indicus)2Only into bird and3Only chicks cloaca Samples, Extraction intestinal microbial totalDNAThe16 S rRNAHigh Flux sequencing of Methods Analysis and compare the two age stage birds intestinal microbial of Flora structure and composition difference. Study found bar-headed goose chicks cloaca microbial belongs9A door content highest of before5A door respectively Is shuttle of door (48.29%), Thick-walled bacteria door (22.21%), Deformation of the door (22.07%), Actinomycetes door (5.02%) And soft wall bacteria door (1.93%). Into bird cloaca microbial belongs17A door most of in turn is the deformation of the door (64.69%), Thick-walled bacteria door (23.92%), Blue bacteria (8.48%), Actinomycetes door (1.43%) And shuttle of door (0.56%). In of the genus level bar-headed goose chicks cloaca microbial belongs18A of made bird containing24A. Into bird cloaca microbialαDiversity was significantly higher than that chicks (P<0.05Welch''''sT-Test). 186A operation classification unit (OTU) Belongs to into bird and chicks there are and other640AOTUAnd90AOTUThe respectively belongs to into bird and chicks. Chicks in67.39%OfOtusIs into bird of some. Based onOTUThe clustering results and age group consensus. This results to know birds intestinal microbial and Host age change between the relationship have certain of reference value. 收起
