Values with different lowercase letters (a and b) indicate significant differences among treatments on the same time. Values with different uppercase letters (A and B) indicate significant differences between 0 h and anaerobic state (A). CK, whole-plant corn silage without any lactic acid bacterial suspensions; CSL, whole-plant corn silage treated with lactic acid bacterial suspensions prepared from whole-plant corn silage; ESL, whole-plant corn silage treated with lactic acid bacterial suspensions prepared from Elymus sibiricus silage. A, anaerobic state. SEM, standard error of means.
