Extract

Whole-crop cereals provide both a concentrated supply of energy and a source of roughage for ruminants, but their nutritive value depends on the digestibility of the grain and straw components (Williams et al., 1983). Preservation with urea provides storage stability, a source of N and may also increase the digestibility of the fibrous components (Wilkinson 1990). The effectiveness of preservation, and intake may be influenced by the physical treatment of the crop, and the scale of this effect may differ between crops. The objective of this experiment was to investigate the effect of choice of crop, and of chopping before and after alkali treatment on the dry matter (DM) intake and digestibility of whole-crop cereals, and on the daily liveweight gain of heifers fed on them.
