A grazing trial was conducted in the winter of 1996-97 to compare the feeding value of soybean stubble to that of cornstalks. Irrigated bean residues were stocked at 0.5 animals/acre, while irrigated corn residues were stocked at 1.2 animals/acre. Calves grazing cornstalks gained (0.17 lb/day) faster (P = .003) than calves consuming soybean stubble (-0.03 lb/day). In addition, calves grazing cornstalks remained in fields 14 days longer. Diet samples were collected on both corn and soybean residues. Ruminally fistulated steer calves grazing bean stubble consumed diets high in crude protein (12- 25%), but low in organic matter digestibility (40-46%). Calves grazing cornstalks consumed diets from 5-6% crude protein and 60-65% digestibility.
