This experiment was conducted to determine the effect of dietary supplementation with copper sulfate and cupreous N-carbamylglutamate chelate (NCG-Cu) on the growth performance, serum biochemical profile, immune response, tissue mineral distributions, and fecal excretion of minerals in nursery piglets. Eighteen healthy nursery piglets were randomly assigned to 3 dietary treatments consisting of no copper in either form (control), 650?g/t copper sulfate (650?g/t Cu) or 320?g/t NCG-Cu (320?g/t NCG-Cu) for 35 days. Pigs fed the 320?g/t NCG-Cu diet showed a significantly (P?P?P?Abbreviations: NCG: N-carbamylglutamate chelate; ADG: average daily gain; ADFI: average daily feed intake; F/G: feed to gain ratio; ALB: albumin; GLU: blood glucose; CREA: creatinine; ALP: alkaline phosphatase; ALT: alanine aminotransferase; AST: aspartate amino transferase; GLB: globulin; TC: total cholesterol; TP: total protein; urea: Urea; D-BIL: direct-acting-bilirubin; T-BIL: total bilirubin; UA: urate; CK: creatine kinase; LDH: lactate dehydrogenase; IgG: immunoglobulin G; IgA: immunoglobulin A; IgM: immunoglobulin M; C3: complement C3; LD: longissimus dorsi; ICP-OES: inductively coupled plasma optical emission spectrometry; AA: amino acid; GIT: gastrointestinal; Cu-Met: Cu-methionine; CP: crude protein; NDF: neutral detergent fiber; ADF: acid detergent fiber. |
