  1. BC: body condition; D × BC: interaction between diet and body condition
  2. 1The abundance of bacterial groups was expressed as log10 16S rRNA gene copies / g of fresh faeces and of functional gene was expressed as log10 gene copies of total DNA / g of fresh faeces
  3. 2Values within a row not sharing a common superscript are significantly different
