Influence of Abomasally Administered Safflower Oil on Fat Composition and Organoleptic Evaluation of Bovine Tissue

Abstract

Two experiments were conducted to determine the effect of abomasally administered safflower oil on the percentage of C₁₈ fatty acids in tissue of steers. In the first experiment two mature steers were given 460 g of oil daily by injection through an abomasal cannula and, after 58 and 86 days, linoleic acid was 2.4 and 4.9%, respectively, of the long-chain fatty acids in the longissimus muscle. Another steer was fed oil for 86 days and had 0.9% linoleic acid in that tissue. Other tissues had similar percentages of linoleic acid. In the second experiment 15 growing steers were either continuously infused with 280 g of safflower oil daily via abomasal cannula, offered 280 g of oil daily mixed with the diet, or given no oil. At 56 days on experiment average plasma cholesterol was 268, 138, and 103 mg/100 ml for the treatments, respectively. Perianal fat was 8.8, 1.9, and 1.8% linoleic acid. Copyright © 1974.
