  1. NDF: neutral detergent fibre; SEM: standard error of mean
  2. aControl: without PBLC; PBLC-L: lower dose (80 mg/d) of PBLC; and PBLC-H: higher dose (160 mg/d) of PBLC
  3. bOne outlier for average daily gain (g/d) < 97, hay intake (g/d) < 525, total feed intake (g/d) < 1126, and hay intake (g/kg BW) < 15.3 was removed for PBLC-L (n = 7) before statistical analyses
  4. cContrast: 1 = linear effect; 2 = quadratic effect; and 3 = Control versus both PBLC groups
  5. dAverage daily gain and the initial BW to calculate this gain are based on the last 21 d of the study to nullify the effect of rumen fill during the first week that might have occurred due to changes in feed intake by PBLC
  6. #/*Mean values differ compared with the control at P < 0.10/0.05
