Dietary antibiotic increased (Pb0.05) N and energy digestibility at d 21. Antibiotic
supplemented diets led to a higher (Pb0.05) DM digestibility in pigs at d 42. The coefficient of
apparent total tract digestibility (CATTD) of DM and N was increased (Pb0.05) by HEM treatments
at d 42 compared with non-HEM treatments
