Effects of the consumption of polyunsaturated fatty acids on the oxidative status of adult dogs

“…Four experimental diets were prepared using each of the lipid sources, supplemented or not supplemented with 500 mg of an algae-based natural antioxidant (AOX -EconomasE, Alltech Inc. Araucária, Brazil)/kg diet: 1) soybean oil enriched with DHA (UNS, unsaturated fatty acid), 2) soybean oil enriched with DHA and the natural algae-based antioxidant (UNS AOX, unsaturated fatty acid + EconomasE), 3) bovine tallow (SAT, SFA fat), or 4) SFA with AOX (SAT AOX; SFA + EconomasE) ( Table 2). This level of AOX supplementation has been seen to have a beneficial effect on cats (Ogoshi et al, 2016). All diets were formulated to guarantee the nutritional and energetic needs of adult dogs (FEDIAF, 2016).…”

“…The imbalance between the production of free radicals and the ability of the body's antioxidant systems to eliminate them is known as oxidative stress. The inclusion of natural ingredients with antioxidant properties has been investigated in companion animals (Salas et al, 2008;Ogoshi et al, 2016), mainly because supplementation with synthetic antioxidants, such as butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA), has been perceived as unwanted by the owners. The present study evaluated the alterations of the oxidative stress markers in adult dogs fed with high levels of unsaturated fatty acids from the mixture of soybean oil enriched with DHA supplemented with natural algae-based antioxidant.…”
