摘要

The effect of dietary selenium (Se) and/or conjugated linoleic acid isomers (CLA) on growth performance and CLA isomers profile of femoral muscles was investigated in female rats. Rats fed Se and/or the CLA mixture responded by decrease body mass gain, whereas Se and the trans-10,cis-12 isomer (t10c12) significantly increased both body mass gain and feed con-version efficiency. Only the CLA mixture, the t10c12 isomer decreased feed intake. The CLA isomers in diets significantly increased the isomerslevel in muscles, while Se and the CLA mixture or the t10c12 isomer considerably increased the isomers content in muscles. The con-centration ratio of the t10c12 isomer to the c9tl 1 isomer in examined tissues and organs de-creased compared to the concentration ratio of these isomers in the standard mixture of CLA isomers in the diets.
