Commercial meat-type chickens (broilers) have become less active as production practices have increased the rate at which these birds gain weight. This inactivity could result in skeletal abnormalities that adversely affect animal health and production cost. This study investigated a treadmill regimen to increase the bone movement of broilers and force the broilers into an abnormally high level of physical activity. Beginning at 3 weeks of age, treatment birds were required to walk 5 days a week on a treadmill at a pace of 0.45 m/s for 30 min. The working hypothesis was that increased bone movement of broiler chicken accelerates skeletal development and strength. Results indicated that treadmill pacing did not affect the body mass of the bird during normal growth but did affect (p≤0.05) the length and width of the bird's shank. The treatment reduced tibia length by approximately 8% and tibia midpoint cross-sectional area by 25%. The shear strength and bone mineralization of the tibia was not affected by the increased bone movement. Overall, the increased activity did not impact the structural integrity of the broiler's tibiae. © 2007 American Society of Agricultural and Biological Engineers. |
