Bar-headed goose into bird and chicks cloaca microbial of contrast analysis

Abstract

Intestinal Microbial by maintain steady-state, auxiliary digestion and promote immune system development and style maintenance host of health state. 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 collected bar-headed goose (Anser indicus) 2 only into bird and 3 only chicks cloaca samples, extraction intestinal microbial total DNA, the16 S rRNA High 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 belongs 9A door content highest of before 5A door respectively. 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 belongs 17A 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 belongs 18A of made bird containing 24A. Into bird cloaca microbialα diversity was significantly higher than that chicks (P < 0.05Welch’sT-Test). 186A operation classification unit (OTU) belongs to into bird and chicks. There are other 640A OTU and 90A OTU, respectively belongs to into bird and chicks. Chicks in 67.39% of OTUs is into bird of some. Based on OUT, the clustering shows results and age group consensus. The results are to know birds intestinal microbial and host age change between the relationship that have certain reference value.
