Background  There are growing evidences showing that gut microbiota should play an important role in host appetite and feeding behavior. However, what kind of microbe(s) and how they affect porcine appetite remain unknown.    Results  In this study, 280 commercial Duroc pigs were raised in a testing station with the circadian feeding behavior records for a continuous period of 30–100 kg. We first analyzed the influences of host gender and genetics in porcine average daily feed intake (ADFI), but no significant effect was observed. We found that the  Prevotella -predominant enterotype had a higher ADFI than the  Treponema  enterotype-like group. Furthermore, 12 out of the 18 OTUs positively associated with the ADFI were annotated to  Prevotella , and  Prevotella  was the hub bacteria in the co-abundance network. These results suggested that  Prevotella  might be a keystone bacterial taxon for increasing host feed intake. However, some bacteria producing short-chain fatty acids (SCFAs) and lactic acid (e.g.  Ruminococcaceae  and  Lactobacillus ) showed negative associations with the ADFI. Predicted function capacity analysis showed that the genes for amino acid biosynthesis had significantly different enrichment between pigs with high and low ADFI.    Conclusions  The present study provided important information on the profound effect of gut microbiota on porcine appetite and feeding behavior. This will profit us to regulate porcine appetite through modulating the gut microbiome in the pig industry.
