Abstract
EIGHTY-FOUR pigs were employed in two trials to study the effect of dietary supplements of copper and vitamin E on the growth of pigs and on the composition and stability of their depot fat. Neither copper nor vitamin E significantly affected the growth rate or feed efficiency of the pigs. Supplemental copper significantly (P<.01) decreased the melting point of the depot fat by increasing the proportions of UFA contained therein. These changes increased the oxidative susceptibility of the depot fat. Further supplementation of the diets with vitamin E improved the oxidative stability of the depot fat from copper-fed pigs.
