  1. BC: body condition; BCS: body condition score; BW: body weight; D × BC: interaction between diet and body condition; EI: energy intake; FI: food intake, g/d: g per day; PI: protein intake, SCFA: short-chain fatty acids
  2. 1Values within a row not sharing a common superscript are significantly different
  3. 2μmol/g and μmol/kg is expressed as the concentration to 1 g and 1 kg faecal samples, respectively
  4. 3Total SCFA = acetate + propionate + butyrate + isobutyrate + isovalerate + valerate
