  1. a,b,cValues with different characters in superscripts were different (P < 0.05) in the same row
  2. 1Treatment means are reported as least squares means and are based on 6 observations per treatment
  3. 2The apparent total tract digestibility (ATTD) of nutrient and energy values of oat bran and wheat bran were calculated using difference method in diets containing 36% oat bran or 27% wheat bran. DE Digestible energy; ME Metabolizable energy; NE Net energy; SEM Standard error of the mean
  4. 3The – and + symbol represents enzyme-free dietary treatment and enzyme addition dietary treatment, respectively
