Two trials conducted in 1996-1997 evaluated dried poultry waste relative to soybean meal for cows grazing winter forages. In Trial 1, cows grazing native Sandhills winter range received: 1) no supplement; 2) urea; 3) 22% dried poultry waste+urea; 4) soybean meal; 5) 22% dried poultry waste+soybean meal; or 6) 44% dried poultry waste. Cows receiving supplements gained more weight (P<.001) and maintained greater body condition (P<.001) than unsupplemented cows. Cows receiving urea gained less (P<.10) than cows receiving more natural protein, although body condition remained similar. In Trial 2, cows grazing cornstalks received supplements containing either soybean meal or dried poultry waste; however, gains were not different.
