Abstract:

The objective of this study was to investigate the effects of different dietary fiber levels on cecum microflora diversity of Carlos geese. Ninety healthy Carlos male geese with 35 days old were divided into 2 groups (n=45) with 3 duplicates for 15 per duplicate, and then fed with diets containing 5% (L group) or 8%(H group) crude fiber using alfalfa as the crude fiber sources, respectively. After feeding 42 days, caecum microflora was determined using MiSeq PE300 sequencing platform. The results showed that caecum microflora of goose in H group included 17 phylums and 199 genera, while caecum microflora of goose in L group included 19 phylums and 226 genera. The bacteria diversity of each sample between the two groups was similar (P>0.05). The relative abundance of Verrucomicrobia, Deferribacteres, Desulfovibrio, Prevotella, Helicobacter, Mucispirillum and Akkermansia of H group significantly increased compared to L group (P<0.05); The relative abundance of Synergistetes, Euryarchaeota, Bacteroides and Methanobrevibacter of L group significantly increased compared to H group (P<0.05). These results suggest that there is no significant difference in the bacteria diversity of cecum of goose fed with 5% or 8% crude fiber, however, the relative abundance of Desulfovibrio, Prevotella, Helicobacter, Mucispirillum, Akkermansia, Bacteroides, Methanobrevibacter are significantly different between the two groups.
