SEM, standard error of means; DM, dry matter; FW, fresh weight; NH₃-N, ammonia nitrogen; TN, total nitrogen.

¹⁾

C, no additive control; L, Lactobacillus plantarum; M, molasses; ML, molasses+Lactobacillus plantarum.

²⁾

D, ensiling days; T, treatments; D×T, interaction between treatments and ensiling days.

p<0.05; NS, not significant.

^a–d

Values with different small letters show significant differences among ensiling days in the same treatment (p<0.05).

^A–D

Values with different capital letters show significant differences among treatments in the same ensiling days (p<0.05).
