The effects of conjugated linoleic acid (CLA) isomers and/or selenium on rat growth performance and levels of some fatty acids (FA) in femoral muscles and perigonadal were investigated. Feeding a mixture of CLA isomers, the trans-10, cis 12 isomer or selenium tended to decrease the rats' body weight compared with the control animals, whereas a diet supplemented with both Se and the trans-10, cis-12 isomer produced the highest increase in body weight gain and the higest feed conversion efficiency. None of the experimental diets had any influence on brain, kidney, pancreas or liver veight, while they significantly increased spleen mass. The interaction between Se and mixture of CLA isomers or the trans-10, cis-12 isomer most effectively protected CLA isomers from peroxidation damage and/or catabolism muscles
