  1. Means in rows with different letters differ at P < 0.05.
  2. aA is the estimated asymptotic gas production; B is the time of incubation at which half of the asymptotic gas production has been formed; C is the sharpness of the switching characteristic for the profile; RmaxG is the maximum rate of gas production; TRmaxG is the time at which maximum rate of gas production is reached; R is the fractional rate of fermentation.
  3. bIn vitro organic matter digestibility.
