Growth performance and intestinal health of broilers fed a standard or low-protein diet with the addition of a protease

Cobb chicks (392; 1-42 d) were divided into four treatments (seven replicates of 14 birds each). There were two feed formulations: a standard diet (SD) and a low crude protein and digestible amino acids diet (Low CPA 1.25 g kg−1). Performance was evaluated by feeding phases (1-7, [...]
