| The aim of the study was to evaluate the effects of adding ractopamine (RAC) and amino acids (AA) to the diet on growth performance, carcass characteristics, commercial cuts yield, meat quality and residues in liver and muscle. Ninety-two crossbred castrated pigs (97.96 ± 2.32 kg) were randomly assigned to one of two dietary treatments: a Control diet with 0 mg kg-1 of RAC and a RAC+AA diet with 10 mg RAC kg-1, for the last 27 days. Pigs of RAC+AA group had greater average daily gain (ADG), gain to feed ratio (G:F) and final bodyweight (P≤0.05) and tended to have lower average daily feed intake (ADFI) (p=0.084) than Control pigs. Carcasses from RAC+AA animals were heavier than controls (P≤0.05). Dressing percentage and backfat depth... |
