The study was performed on 162 Cobb broiler chickens, divided into 3 groups, 54 birds each. Three experimental diets were prepared, each as starter, grower and finisher. The control diet (C) was wheat-based, while experimental diets contained 450 g/kg of hulless or hulled barley. Diets were fed ad libitum. On day 42 of age 4 males and 4 females from each group were sacrificed and the physicochemical parameters in femurs measured. Hulless barley significantly reduced the circumference of femoral bones, while increasing their fracture resistance. The ratio of breakage force to bone mass and circumference showed significant resistance improvement in the group fed hulless barley. Hulless barley significantly increased the Ca and Mg content in the femoral bones.
