Avizyme treatments significantly improved ADG over the PC during periods 2A, 3A, A and B. However, period 1A had significant decreases in ADG with enzyme inclusion. Period B experienced FCR improvement with AZ. Both energy and protein ileal digestibility were decreased with enzyme inclusion during periods 1A, 2A, 3A, 4A, 5A, A and B. Villus height and crypt depth did not respond to dietary treatment, though a significant interaction of age and villus height occurred.
