Since feed accounts for 65-85% 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 objective of the experiment was to determine the effect of feeding either fermented whole crop (FWC), Head-cut or Low-cut processed urea treated whole crop wheat (Alkalage) in comparison to ad libitum cereals/protein on the performance of intensively finished continental cross beef cattle.
