This study investigated the carcase composition of Taiwan simulated native chickens at different stages of growth. The results indicated that the carcases of male chickens exhibited significantly larger protein mass and water mass than those of females during weeks 7 to 20; as was the ash mass during weeks 8 to 20. However, the fat mass of the carcases of female chickens was larger than that of males during weeks 14 to 20. Separate regression equations were derived for the relationship between protein mass, fat mass, ash mass and water mass and both carcase weight and age of both male and female chickens.
