^a–f Means within the same row with different superscripts differ significantly among ensiling days (one-way ANOVA, p < 0.05, Tukey’s post hoc test). ^A–C Means within the same column with different superscripts differ significantly among OS treatments (one-way ANOVA, p < 0.05, Tukey’s post hoc test). 0%, 0% oat silage; 11%, 11% oat silage; 22%, 22% oat silage. OS, oat silage content; FTMR, fermented total mixed ration; DML, dry matter loss during the ensiling period; FM, fresh matter; NDF, neutral detergent fiber; ADF, acid detergent fiber; CP, crude protein; WSC, water-soluble carbohydrates; NPN, non-protein nitrogen; SEM, standard error of the mean.
