Possible Interaction: Fish Oils and Conjugated Linoleic Acid

“… FO in the diet … flow of total CLA leaving the rumen with an average across silages of 0.22, 0.31, 0.41 and 0.44 g/day for …, 10, 20 or 30 g FO/kg, respectively, with a linear interaction effect between the two silages (P = 0.03).”

“ Fish oil supplementation increased the concentrations of C18:1 trans-, cis-9, trans-11 conjugated linoleic acid ( CLA ), C20:5 (n-3) and C22:6 (n-3) within ewe plasma, milk and lamb plasma.”

“LO-MA and LO-FO-MA increased the contents of c9,t11-conjugated linoleic acid ( CLA ) and c9,t11,c15-conjugated linolenic acid (CLnA) compared to LO.”

“ CLA content in milk fat was higher in response to fish oil or sunflower and fish oil blend compared with control (T1).”

“Therefore, CLA with FO combination might be a novel dietary supplement to reduce fat mass and improve BMD.”

“Proportions of … acid), cis-9 trans-11 conjugated linoleic acid (CLA; 0.52, 0.90, 1.11, and 1.52 g/100 g of fatty acids), and trans-10 …, 0.14, 0.13, and 0.16 g/100 g of fatty acids) in milk fat were increased by FO ….”

“ CLA caused significant decreases in C18:1 fatty acid levels in both the BTC and FOC groups in epididymal fat pads.”

“… FO supply linearly increased (P<0 x 05) the concentration of the cis-9, trans-11 and trans-10, cis-12 isomers of CLA and trans-11 18 : 1 predominantly in the neutral lipid fraction of intramuscular total lipid, and linearly decreased the n-6:n-3 PUFA ratio.”

“ Fish oil added to ruminant diets increases the CLA concentration of milk and meat, an increase thought to arise from alterations in ruminal biohydrogenation of unsaturated fatty acids.”

“Apparently, many of the physiological effects of CLA can be reversed by fish oil.”
