| Cows were assigned randomly to indoor silage feeding (with 2 h outdoor exercise) or part-time grazing treatment in two different experiments. One group was kept in confinement with ad libitum grass silage within each experiment. The other group had ad libitum grass silage indoors and they were put out on grass pasture during part of the 24 hour period, 12 hours (night, Experiment 1) and 6 hours (day, Experiment 2) in June, July and August. In Experiment 2, the concentrate (9 kg d-1) was given at two crude protein levels: high crude protein [185 g kg-1 dry matter (DM)] and low crude protein (135 g kg-1 DM). In Experiment 1, night-time grazing increased total DM intake and milk (3.9 kg d-1) production. There was interaction between month and forage feeding... |
