Approach: Fifteen weanling barrows (initial BW: 9.6 kg) were surgically fitted with a T-cannula in the distal ileum. Animals were randomly allocated to three dietary treatments with five pigs per treatment during a 6- period experiment. Dietary treatments included: (1) a basal diet (BD) containing mainly corn and soybean meal, (2) BD + 27.5 mg kg-1 of carbadox and (3) BD + 55.0 mg kg-1 of carbadox. Treatment diets were provided during period 2-4; the BD was fed to all pigs during period 1, 5 and 6. Ileal samples were collected on d 6 and 7 of each period. Results: In pigs fed only the BD throughout the experiment, the AID of CP and many AA was greater during period 2-4 than during period 1 (p
