Níveis séricos de enzimas de função hepática em frangos de corte de criação industrial clinicamente saudáveis Serum levels of hepatic enzyme function in clinically healthy broiler chickens

<abstract language="eng">The values for the main hepatic enzymes included in the profiles of screen clinical biochemistry, alanine-aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (FA), lactate desidrogenase (LDH) and gamaglutamiltransferase (GGT), in samples of serum of broiler chickens in industrial system, clinically healthy, starting from the seventh day of life, until the slaughter (42 days) in weekly intervals were determined. Significant variations were not observed in the analyses in relation to the age of the birds for none of the appraised enzymes
