Pigs were weaned at 16 to 20 days of age and fed diets containing either dried whey, dried porcine solubles (DPS), or condensed porcine solubles (CPS) for 3 weeks, followed by a common diet for 2 weeks. The results of the trial showed that 5% of either DPS or CPS can replace dried whey protein in diets for weanling with no effect on growth performance up to 5 weeks after weaning
