A, effect of treatment; D, effect of silage days; A × D, interaction between treatment and silage days; Means with unlike lower case superscripts letters (a–c) differ among ensiling days (P < 0.05). Means with unlike upper case superscripts letters (A–C) differ among treatments (P < 0.05). SEM, standard error of mean. CP, CIP, EIP represent the silage of CK, CIL, EIL group respectively for 3, 7, 14, 28 days. NDS, natural detergent solute; ADL, acid detergent lignin; CL, cellulose; HC, hemicellulose; WSC, water-soluble carbohydrate
