The aim of this study was to evaluate the influence of different iron and copper levels from the compound feed over the bioproductive performances of young swine, also the evolution of the contained iron and copper in blood, liver, fat and muscles, in the conditions in which during 2 weeks iron and copper marked with radioactive isotope 56Fe and 64Cu have been used. The researches have been made on the number of 75 pigs from the LS-345 Peris Synthetical Line, being divided in 3 batches uniformly by body weight (11.5 kg). The swine nutrition from all the 3 batches has been realized with the same compound feed, the differences being in the different proportion of the two microelements (iron and copper) from vitamino-mineral premix (batch no.1 received 95 mg iron/kg compound feed and 6 mg copper/kg, batch no. 2-85 mg iron/kg compound feed and 5 mg copper/kg, batch no. 3-75 mg iron/kg compound feed and 4 mg copper/kg). The best bioproductive performances (average daily gain, average daily consumption, specific consumption) have been obtained by the young swine in which’s compound feed level has been of 85 mg iron/kg and 5 mg copper/kg. After giving the radioactive isotopes the highest values of iron have been observed in liver and muscles, moreover in case of copper, they can be found in liver. For the young swine copper is a growing biostimulating factor, influencing positively the iron metabolism.
