Notes:
Cervical, thoracic, lumbar and sacral vertebrae, plus rib and femur bones were removed from 13 bovine of a wide age range (89–2783 days) to elucidate changes in bone composition as a function of age and anatomical location. Percent dry matter, ash, calcium and phosphorus increased with age while nitrogen and sulfur decreased. The calcium/phosphorus ratio remained relatively constant during growth. Dry matter, ash, calcium and phosphorus percentages increased from the anterior to the posterior of the vertebral column, while sulfur and nitrogen decreased. Thus, bone ossification advanced from the posterior to the anterior vertebrae. The femur contained the largest proportion of ash, calcium and phosphorus of the six bone types investigated.
