Food utilisation efficiency and body composition are very important determinants of profitability in poultry meat production. In commercial meat chicken breeding programs, improvement in lean tissue deposition efficiency is typically addressed through within and between line selection for growth rate, food utilisation efficiency for growth, and body composition. Most of the selection studies in this area have been undertaken with chickens, and notwithstanding the recognised role of Japanese quail as a commercial poultry species and as a genetic model for chickens, little work has been undertaken with this species in this area. The purpose of the study described here was to determine in the one selection experiment, the direct and correlated responses to selection for growth rate, food utilisation efficiency and carcass fatness in Japanese quail, to facilitate the assessment of appropriate selection strategies for improvement in the efficiency of lean tissue growth rate in this species.
