High DF increased the relative abundance of Blautia, Faecalibacterium and Peptococcus in the caecum, the mid colon and faeces, reduced the intestinal concentrations of total short-chain fatty acids (SCFA) (P = 0.020) and acetate (P = 0.011) but slightly increased butyrate pools in the large intestine (P ≤ 0.050) compared to low DF. High protein increased the SCFA (P = 0.026) and propionate (P = 0.044) concentrations in the gut.
