Since feed accounts for 75-85% of the variable costs of beef production, the use of alternative feeds and high-energy forages that have a lower cost per unit of energy are worthy of investigation. The technique of harvesting cereals where the whole-crop is harvested at a dry matter (DM) content of 650-750g/kg with the harvester fitted with a grain processor has recently been developed. The objective of this trial was to determine the effect of feeding either adlibitum processed urea treated whole-crop wheat (Alkalage) or cereals on the performance of Continental cross beef cattle since there is no data on the performance of beef cattle fed Alkalage.
