黄芪茎叶对断奶仔猪盲肠微生物区系的影响
Effect of Astragalus Stem Plant on the Microflora in Gut of Weaned Piglets
摘要
Abstract
The aim of this study was to investigate the effects of different concentrations of Astragalus membranaceus on cecal microflora in weaned piglets.Twenty-four healthy crossbred piglets were randomly divided into the control group,2.5％,5％ and 7.5％ power of astragalus plant group,each group had 3 repeats and each repeat had 2 piglets.Test period 28d.llumina Genome Analyzer Ⅱx method adopted to determine Cecum microflora in piglets.It showed that the diversity of micro-organisms in aecum of piglets changed with the added amount of Astragalus plant,however,among them,the highest microbial diversity was 2.5％ groups,which was mainly composed of Firmicutes and Bacteroidetes,the content could reach 92％;at the genus level,the number of dominant species in the stems and leaves of Astragalus 2.5％ and 7.5％ were the highest.In conclusion,adding Astragalus plant in feed of weaned piglets could reduce the pH and and increase microbial diversity,which is beneficial to the healthy growth of weaned piglets.关键词
