In 2 experiments with steers (initial live weight 339 kg) the effect of dried grass, barley and concentrates on the intake of wilted and unwilted grass and whole-crop barley silage was investigated. In both experiments there was no significant effect of silage type on silage dry-matter intake when given alone or with a supplement. In experiment 1, supplementation significantly reduced (P < 0.05) the intake of silage dry matter (DM) from unwilted and whole-crop barley silage. Total DM intake was significantly higher (P < 0.05) for the wilted silage diet than for either the unwilted or whole-crop barley silage diets. In experiment 2 supplementation had no significant effect on total DM intake. Digestible energy intake was significantly higher (P < 0.05) from whole-crop barley silage supplemented with concentrate rather than barley or dried grass and was significantly lower (P < 0.05) from unwilted silage diets (P < 0.05) when dried grass rather than concentrate or barley was given. In experiment 2, ration digestibility and rate of passage of digesta results are reported.
