Abstract: The objective of this work was to establish phenotypic relationships among some production traits (feed conversion rate, feed consumptionFC, residual feed consumption, relative weight gain, weight gain-WG and live weight) and body composition traits in a free-range broiler population (Campero- INTA). Ninety-six males in individual cages between 49 and 79 days of age were used. Weight and feed consumption was recorded weekly. Forty- four broilers were slaughtered at 44 days of age to estimate the initial body composition. All caged birds were slaughtered at 79 days of age and the following weights were recorded: live, carcass (CW), viscera (VW), abdominal fat (AFW), breast, thigh (TW) and feathers. Correlation coefficients between traits were obtained and regression analysis was performed for the evaluation of the influence of production traits over the slaughter proportion gain and slaughter weight gain of the body components. Any proportion gain between slaughters was well explained by the measured and calculated production traits. Only the gain of two body components (CW, TW) was well explained by some of them (WG, FC). There was little association between body components and production traits when they were analyzed independently. But when proportions of body components were correlated with all production traits by a canonical correlation, AFW and VW proportions were the most important variables, with opposite signs, in the association. Some observed correlations encouraged us to further study these traits for selection criteria.
