Abstract

Dietary linseed oil and selenate affect the concentration of fatty acids and selenium in the spleen, pancreas, and kidneys of lambs

Highlights

The different geometric and positional isomers of conjugated linoleic acid (CLA) differ in their influence on the health of mammals (Belury, 2002; Park and Pariza, 2007; Park, 2009; Husvéth et al, 2011)
Feeding lambs the diet enriched in linseed oil (LO) or SeVI increased the value of the ∆9-desaturase index in the pancreas compared with the control and LOSE groups, while decreased values of this index were found in the spleen and kidneys of lambs fed the LO, SeVI in the diet (SE), or LOSE diet
The diets enriched in 5% LO and/or 2 ppm SeVI resulted in no macroscopic lesions, physiological disorders or pathological changes in the spleen, pancreas, kidneys, liver (Czauderna et al, 2004b), muscles or in any other tissues of sheep (Czauderna et al, 2004a; Niedźwiedzka et al, 2008)

Summary

Introduction

The different geometric and positional isomers of conjugated linoleic acid (CLA) differ in their influence on the health of mammals (Belury, 2002; Park and Pariza, 2007; Park, 2009; Husvéth et al, 2011). Previous studies demonstrated that the CLA isomer content in the body of sheep is altered by oil supplemented to the diet (Czauderna et al, 2004a,b; Raes et al, 2004; Szumacher-Strabel et al, 2004; Niedźwiedzka et al, 2008). Our previous studies documented that diets enriched with LO resulted in an increase in the level of unsaturated fatty acids (UFA), especially PUFAn-3 and sum of CFA (ΣCFA) in the liver, adipose tissues, and muscles of sheep (Czauderna et al, 2004a,b; Niedźwiedzka et al, 2008).
