Treatments were untreated silage (Control); SDA3, sodium diacetate applied at 3 g/kg fresh weight; SDA6, sodium diacetate applied at 6 g/kg fresh weight; LP, L. plantarum; LB, L. buchneri; LP + LB, L. plantarum + L. buchneri (1:1 ratio). Application rate of inoculants was 1 × 10⁶ cfu/g fresh weight.
