During the past three years ground alfalfa hay has been used at this station in protein supplements for growing pigs, to reduce protein consumption. Previous trials have shown that levels of from 19 to 30 per cent alfalfa in protein supplements results in satisfactory consumption and gains. This experiment was conducted to compare various levels of soybean oil meal and tankage in supplement's containing 19 to 30 per cent ground alfalfa hay.
