  1. a, b and c: Means in the same row with different superscripts are significantly different at (p < 0.01)
  2. SE, standard error; NS, nonsignificant difference
  3. *Significant difference at (p < 0.05), **Significant difference at (p < 0.01). Because group feeding was used in the feeding trial, the data of feed intake did not subject to statistical analysis
