Abstract

Effects of selenium on fatty acid concentration and antioxidant status of erythrocyte membrane in lambs fed linseed or sunflower oil diet

Highlights

  • Many studies have been investigated to increase the content of polyunsaturated fatty acids (PUFA) in lamb tissues by feeding diets supplemented with rumen protected or unprotected oilseed or free oil rich in n-6 or n-3 PUFA

  • The objective of the present study was to assess the effects of Se and FA supplementation on FA composition and antioxidant status of erythrocyte membrane in lambs

Summary

Introduction

Many studies have been investigated to increase the content of polyunsaturated fatty acids (PUFA) in lamb tissues by feeding diets supplemented with rumen protected or unprotected oilseed or free oil rich in n-6 or n-3 PUFA. Selenium (Se) has been shown to affect the fatty acid (FA) composition in mouse muscle and chicken eggs (Czauderna et al, 2004a; Pappas et al, 2005). Information regarding effects of Se on FA composition in sheep is rare (Czauderna et al, 2004b,c), and there were no data published previously about the interaction of PUFA and Se on FA concentration and antioxidant status of erythrocyte membrane. The objective of the present study was to assess the effects of Se and FA supplementation on FA composition and antioxidant status of erythrocyte membrane in lambs
