| description | The hypothesis tested was that dietary inclusion of insect meal (IM) causes an alteration in the cecal microbiota composition and its fermentation activity of growing pigs. Five-week-old male crossbred pigs were randomly assigned to three groups of 10 pigs each, and fed isonitrogenous diets either without (CON) or with 5% IM (IM5) or 10% IM (IM10) from <i>Tenebrio molitor</i> larvae for four weeks. The relative abundance of the phylum Bacteroidetes was lower in group IM10 than in group CON (<i>p</i> < 0.05), whereas the relative abundance of Firmicutes and the Firmicutes:Bacteroidetes-ratio tended to be higher in groups IM10 and IM5 than in group CON (<i>p</i> < 0.1). The relative abundance of the Proteobacteria tended to be higher in group IM10 than in groups CON and IM5 (<i>p</i> < 0.1). The concentrations of the total short-chain fatty acids in the cecal digesta did not differ between the three groups, but the concentrations of the branched-chain fatty acids in the cecal digesta were higher in group IM5 and IM10 than in group CON (<i>p</i> < 0.05). The present study shows for the first time that the replacement of soybean meal by <i>Tenebrio molitor</i> larvae meal causes a shift of the cecal microbial community and its fermentation activity in growing pigs. |
