Conteúdo: | Two experiments were conducted to study the relative bioavailability of Cu in a Cu-lysine complex with that of reagent grade CuSO4.5H2O for chicks and lambs. Chicks were fed a basaldiet (11 mg kg-1 Cu, dry matter (DM) basis) or the basal diet supplemented with 150, 300 or 450 mg kg-1 Cu from either of the two Cu sources for 18 days. Birds were killed and liver Cu concentrations determined. Liver biopsy samples were collected from wether lambs who then fed the basal diet (9.5 mg kg-1 Cu DM) or the basal diet supplemented with 60, 120 or 180 mg kg-1 Cu from either source for 10 days.  Copper in the initial biopsy was used as a covariate in the multiple linear regression of log 10 final liver  Cu concentration on added dietary Cu concentration.  Slope  ratio   comparisons gave relative Cu bioavailability values of 99 and 68 for  Cu-lysine in chicks and lambs,  respectively,  compared with 100 for  CuSO4.5H2O for both species.
