| Abstract: | Characteristics of marrow lipids in bones from three different anatomical locations (cervical, lumbar, femur) in steers and cows on low energy (range) or high energy (feedlot) diets are reported. Cervical marrow contained the least and femur marrow the most total lipid and triglycerides (TG) were the major type of lipid present in all marrows. Phosphatidyl choline was the major PL present in all marrows. The predominant fatty acids were 16:0, 18:0 and cis 18:1. There were no consistent effects due to anatomical location of bone, diet or sex upon any of the acids measured. TG structures were similar in all marrows and the fatty acid composition of TG from steer marrow resembled that of steer intramuscular TG. |
