Abstract: The objectives of this study were to derive economic values of objective traits in quality chicken, and to determine the influence of production and market factors on economic values. Economic values were derived using a deterministic economic model based on profit equations with a fixed amount of broiler meat output of the production system. Especially, economic value of meat quality was derived by an optimum range model. As the result shows that the relative importance of the feed conversion ratio is the most, reach 36.10%, then finishing weight and meat quality trait, reach 29.94% and 22.95%, respectively. On the other hand, the relative importance of reproductive traits is smaller. This study shows that, in an integrated broiler enterprise, the economic returns of selection for reproduction traits are much smaller than those of production traits. Economic values of traits in the integrated system were also derived for situations where technical parameters or prices of productive factors were changed (10% increase or decrease). A general conclusion from these sensitivity analyses is that the economic values are sensitive to production levels, product prices and feed prices; there are both linear and nonlinear relationships between economic values and production circumstances.
