E-mail: ggbotelho@ufrrj.br This work has determined the urinary protein and creatinine concentrations with classical colorimetric methodology, as well as the urinary protein/creatinine ratio (UP/ UCr) in dairy cattle raised at Seropedica, RJ, Brazil. The respective mean values of 18.4 mg/dL, 60.9 mg/dL, and 0.33 were observed, which may be considered referential values for healthy animals, like those used in this work (lactating females of dairy cattle, raised in semi-extensive system).
