| 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... |

| Once livestock is slaughtered the carcass of body obtained represents the main commercial product, and is valued in terms of quality. The aim of this work was to characterize and evaluate the carcasses of Araucano creole lambs. Thirteen Araucano lambs were slaughtered at 221±15 days of age weighing 32±2 Kg. The hot carcass was weighed and after 24 hours at 4C the cold carcass was weighed. The characteristics of conformation, fat cover and regional composition of the carcass were evaluated according to Chilean regulation standards. The tissue composition of the back was also determined, in its three components (muscle, bone and fat). The commercial yield of the carcass was 51.14% and losses due to dehydration of the carcass were recorded at 3%. The... |
