Popis: This experiment was conducted to measure the effects of dietary supplementation with copper sulfate and cupreous N-carbamylglutamate chelate (NCG-Cu) on the growth performance, serum biochemical profile and immune response, tissue mineral levels and fecal excretion of minerals of weaning piglets. Eighteen 28-d-old healthy weaning piglets (initial body weight = 6.34 ± 0.10 kg) were individually housed and randomly assigned to receive one of three diets containing no copper in either form (Control), 650 g/t copper sulfate (650 g/t Cu group) or 640 g/t NCG-Cu (640 g/t NCG-Cu group) in the final feed for 14 days. These data indicate that 640 g/t NCG-Cu was as effective as 650 g/t Cu for stimulating growth, immune response, and improving F/G in weaning piglets. Fecal Cu excretion decreased in piglets from the 640 g/t NCG-Cu group, which received 160 mg/kg Cu compared with the fecal CU excretion observed in the piglets from the 650 g/t Cu group, which also received 160 mg/kg Cu. Therefore, 640 g/t NCG-C...
