高通量测序分析酵母培养物对肉仔鸡盲肠菌群的影响
Effect of Different Fermentation Duration of Yeast (Saccharomyces cerevisiae) Culture on the Intestinal Microbiota by Miseq High-throughput Sequencing
摘要
Abstract
This study was conducted to investigate the effect of different fermentation time of Yeast (Saccharomyces cerevisiae) Culture on the intestinal microbiota.One-day-old AA 336 broilers with the comparable relative quality were randomly assigned to 7 groups with 6 replicates of 8 broilers each.The broilers in the control treatment A were only fed a basal diet,and treatment B,C,D,E,F were yeast culture groups,supplemented with fermentation time at 12 h,24 h,36 h,48 h and 60 h of yeast culture,and treatment G was Diamond V XP,respectively.The experiment was based on 42 d to 7 d preliminary trial period.After 42 d.Cecum contents were collected and the intestinal microbiota was detected by Miseq high-throughput sequencing technology.The results showed as follow:Compared with the control group,at 7~42 d,averaged daily gain (ADG)in C and D group were significantly higher (P<0.05),and that two groups of feed to gain ratio(F/G)were significantly lower.D group had the highest intestinal microbiota diversity while C group,exhibited the lowest species diversity.In the phylum level,Firmicutes was the most abundant bacterial in 7 groups,while the proportion of Verrucomicrobia was higher in C group was against the other group.In the genus level,Bacteroides,Faecalibacterium,lactobacillus,Blautia were the more abundant bacterial in 7 groups.In conclusion,different time of fermentation of yeast culture has a significant effect on intestinal flora,and thus we can control composition metabolites of yeast culture by adjusting the fermentation time,in turn,adjusting the structure of intestinal flora,affect the production performance of animal.关键词
