  1. Means with different letters among the same row indicate significant differences according to the p-value presented
  2. NFC was calculated by subtracting CP, NDF, fat, and ash contents from total DM (Sniffen et al. 1992)
  3. DM (% of fresh weight) dry matter, CP crude protein, NDF neutral detergent fiber, ADF acid detergent fiber, ADL acid detergent lignin, EE ether extract, NFC non-fiber carbohydrates, SEM standard error of the mean
