Abstract
USA. The feeding of whey or lactose to beef cattle fed either fattening or growing rations increased rate of gain. The feeding of 0.50 lb. of whey in fattening rations was more effective than lower or higher levels. Feeding 0.25 and 0.50 lb. whey as additions to wilted silage rations were equally effective in increasing gains. The equivalent amount of lactose as in 0.50 lb. of whey did not appear to produce the same response as whey. No consistent pattern was found for carcass grade, dressing percent or rib eye area.
