The growth and performance of 96 nursery pigs fed crude glycerol was evaluated in a 33 d trial. Pigs were weaned at 21 d of age and had an average start weight of 7.9±1.2 kg (17.4±2.6 lb). Pigs were provided ad libitum access to corn soybean diets containing three levels of crude glycerol, 0, 5, or 10%. Diets were formulated to be ioscaloric and isolysinic. There was no difference in pig performance based on dietary treatment. Crude glycerol can be fed to young pigs as an energy source without growth or performance effects.
