## Abstract

The invention relates to compositions for use as silage inoculants comprising a yeast strain, one or more bacterial stains, and a suitable carrier. The invention also relates to methods of improving livestock animal silage and meat and milk performance of a livestock animal.

## Claims

### Claim 1

A composition comprising: a yeast strain selected from the group consisting of Saccharomyces cerevisiae strain YE206, deposited as Patent Deposit No. NRRL Y-50734; S. cerevisiae strain YE1241, deposited as Patent Deposit No. NRRL Y-50735; or S. cerevisiae strain YE1496, deposited as Patent Deposit No. NRRL Y-50736, a strain of the bacterial species L. buchneri, a pre-ensiled plant material, and a suitable carrier wherein the composition contains from about 101 to about 1010 viable organisms of said yeast strain per gram of the pre-ensiled plant material.

### Claim 2 (depends on 1)

The composition of claim 1, further comprising a bacterial strain selected from one or more of: Lactobacillus plantarum, L. alimentarius, L. crispatus, L. paralimentarius, L. brevis, or Enterococcus facium and mixtures thereof.

### Claim 3 (depends on 2)

The composition of claim 2 wherein the bacterial strains comprise one or more of: LP286, LP329, LP7109 and mixtures thereof.

### Claim 4 (depends on 1)

The composition of claim 1, wherein the composition contains from about 103 to about 106 viable organisms of said yeast strain per gram of said pre-ensiled plant material.

### Claim 5 (depends on 1)

The composition of claim 1 wherein the bacterial strains comprise one or more of: LN4017, LN4637, or LN5689 and mixtures thereof.
