Research On Animal Production

This experiment aimed to evaluate the antioxidant and hypolipidemic effects of Gracilariopsis persica seaweed using 112 Japanese quail with four treatments and four replications in a completely randomized design for 12 weeks. The seaweed Gracilariopsis persica was added to diets in levels of 0, 1, 3, 5 percent. MDA concentration was measured in the yolk as oxidation index after zero, 50, 100 concentration and 150 min iron-induced oxidation. Serum cholesterol, triglycerides, VLDL, HDL and LDL were determined at the end of the experiment (12 weeks). Malondialdehyde concentrations in egg yolk of birds fed diets containing Gracilariopsis persica were lower than the control group (P< 0.05). Also, the birds fed on Gracilariopsis persica diets had lower LDL and cholesterol in their serum compared with control group (P< 0.05). The results showed that Gracilariopsis persica have antioxidant and cholesterol-lowering effects and can be considered as a new feed additive.
