Resting posture influences magnitude of RMR. (a) Log – log plot showing the allometric relationship between RMR and body mass. Filled circles, sitting RMR; open circles, standing RMR. Each marker represents mean data from a single experiment in which a broiler exhibited quiet resting in sitting (solid line: y = 1.287x0.770; P < 0.001) and standing postures (dashed line: y = 1.367x0.873; P < 0.001). (b) Ratio of standing/sitting RMR over development in broilers. There is a significant increase in the energetic cost of standing as birds grow (y = 0.098x + 1.098; P = 0.001).
