Abstract |
A feeding trial was conducted with 10 sheep for 12 weeks to examine the effect of soybean oil (SBO) supplementation on long-chain fatty acids composition, especially cis9,trans11-conjugated linoleic acid (c9,t11-CLA) in fat tissues. Sheep were fed either a SBO supplemented diet (5%, DM basis) or a control diet without SBO. Chopped rye grass hay was fed as roughage. Concomitant increases in contents of total cholesterol (T-C) and HDL-cholesterol (HDL-C) in the plasma of sheep were observed from the SBO supplementation. The supplementation of SBO reduced (p<0.05) the proportions of C16:1, C17:0 and C17:1 but increased (p<0.05) the proportions of C18:0 and octadecenoic acid (t11-C18:1) in the intramuscular fat. The C18:0 proportion only in the subcutaneous fat was increased (p<0.05) by the SBO supplementation. The SBO supplementation slightly increased CLA proportion in the intramuscular fat and subcutaneous fat. |
