THE EFFECT OF COPPER UNDER DIFFERENT FORMS AND LEVELS OF SUPPLEMENT IN THE FOOD OF YOUNG PIGS OVER THE ACCUMULATION OF COPPER AND IRON IN TISSUES AND ORGANS

For this experiment were used 75 crossbreeds pigs Large White x Landrace, starting at the age of two months to eight moths. The 75 pigs were divided in five equal groups: group C–6 mg Cu; group E11-250 mg Cu; group E12--250 mg Cu under kelateted form of solubile phosphatic glass; group E21 -250 mg Cu; group E22 -125 m/ Cu under the form of sulphate.At the end of the experiment there were gathered tests from the liver, the spleen and from the muscles to determine the concentration of copper and iron.The supplimentation of copper in the food of the young pigs has determined a massive accumulations of copper in the liver and minor accumulations in the spleen and muscles. The supplimentation of copper under chelatated from has determined less accumulations in contrast with the cases in which it was used copper under frome of sulphate.The concentration of iron in the liver, spleen and muscles wasn segnificant modifiend by the suppliments with copper.
