Abstract


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 E 22 -125 mg Cu under the form of sulphate.The supplement of copper in the feed of young pigs has determined a significant raise in growth level with 8,5 – 11 % in cases of supplementation with 125 mg Cu.The best results in the case of growing levels have been obtaind in the portions in witch we have used chelated copper.Specific consumption was with 5 % lower that that in witch we supplement copper.
