  1. Data are based on Fuma et al. [52] and Ngwe et al. [53]
  2. aEach fiber source was incubated for 24 h in the rumen and colonized bacteria were quantified by quantitative PCR (qPCR)
  3. bBacteria quantified were Fibrobacter succinogenes (Fs), Ruminococcus flavefaciens (Rf) and Ruminococcus albus (Ra)
  4. cHemicellulose/cellulose ratio indicates the degree of complexity of fiber structure
