The understanding of the mechanisms that differ between breeds of cattle and their ability to deposit intramuscular adipose tissue is imperative to profitable beef production. Thus, the interactions among breeds, metabolic substrates and specific hormones in bovine intramuscular and subcutaneous adipose tissue were investigated. Subcutaneous and intramuscular adipose tissues were obtained from 10 Angus and 9 Santa Gertrudis steers immediately postmortem. The adipose tissues were incubated for 2 h and 48 h with and without 1 mU/ml insulin and 30 mg/ml bovine serum albumin (BSA) to measure the incorporation of /sup 14/C-labeled acetate and glucose into lipid fractions. At the same chronological age, Angus steers had a more youthful lean maturity score, higher USDA marbling scores and higher USDA quality grades than carcasses from Santa Gertrudis steers.
