NUTRITIONAL Cu, Fe INTERRELATION AFFECTED BY ENERGY LEVELS? THE EFFECT OF IRON AND THYROXINE ON PIGS GIVEN EXTRA COPPER

This is the authors' abstract. We don't add key points for this paper.

Iron and thyroxine had at moderate levels effects upon lipid metabolism and copper deposition. Thyroxine acted against effects of iron. Thyroxine produced less fat on the carcasses of the pigs reduced growth, and the feed utilization. Thyroxine also removed the iron influence upon copper deposition. Low energy may thus abolish iron corrections of copper in-balance in animals.
