Extract

Previous studies with whole crop wheat (WCW) fed to dairy cows (Hill and Leaver, 1990) showed that high intakes were achieved relative to liveweight when offered as the sole forage, but there appeared to be a poor utilisation of the ME intake. The reasons for this have not been clarified, but the very high intake of ammonia could be a predisposing cause. The place for WCW is therefore likely to be as a proportion of the total forage. The high pH should make it an ideal complement for silage.

The objective of this experiment was to replace part of the WCW intake with grass silage.
