Effect of Age and Anatomical Location on Composition of Bovine Bone

Abstract

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.

Variability of Selected Components in Mechanically Separated Beef

“…since these bones are easy to hand debone, they usually contain little adherent muscle tissue. Consequently, the product produced from these bones usually contains more marrow than that produced from other bones (Mello et al, 1978). Bones from the vertebral column are more difficult to hand debone and therefore usually contain considerable muscle tissue.…”

Carcass and Empty Body Composition of Hereford and Angus Bulls From Lines Selected for Rapid Growth on High-Energy or Low-Energy Deits

“…In an experiment to study the long-term effects of selection diet on animal performance (Bailey and Lawson 1986), two lines of Hereford cattle (lines I and 2) and two lines of Angus cattle (lines 3 and 4) were selected on high-energy or low-energy diets for an average of l8 yr (Bailey and Lawson 1989 (Kauffman 1978), that bone contains 220 g protein and 180 g fat kg-r (Mello et al 1978), and that the energy contents of protein and fat were 23.5 and 39.3 MJ kg-r, respectively (Webster et al 1976 (a) the small amount of fatty material trimmed from the carcass, and @) the empty body minus carcass, trim, and kidney and abdominal adipose tissues.…”

The biogeochemical imprint of human metabolism in Paris Megacity: A regionalized analysis of a water-agro-food system

“…By far the largest amount concerns the transformation of animal products, particularly slaughtering and cutting activities. Taking into account the cutting balance available for each type of livestock (Benhalima et al, 2015), as well as the N and P composition of each fraction (CIQUAL; USDA; Mello et al,1978;Ternouth, 1990;Little, 1984), waste generation (as blood, viscera, grease, bones, etc.) associated with edible meat production can be evaluated.…”
