Extract

Beneficial effects of inoculants on the nutritive value of well-preserved grass silage for beef cattle have been described (Keady and Steen, 1994). Less information is available on the efficacy of inoculants when untreated grass is preserved badly. The first objective of this study was to determine the effect of one inoculant under such conditions. Since an improvement in nutritive value of silage may be hidden when supplementary concentrates are offered, the second objective of this study was to determine the interaction between silage additive treatment and concentrate supplementation on the nutritive value of the resulting diets.
