Determination and prediction of the energy content and amino acid digestibility of brewer's spent grain for growing pigs.

Two experiments were conducted to determine the energy content and amino acid (AA) digestibility of 10 brewer's spent grain (BSG) for growing pigs, with the goal of developing predictive models for these digestible nutrients based on their chemical composition. In Exp. 1, 66 crossbred barrows (initial body weight (BW): 35.
