Urine protein-to-creatinine ratio in cattle with subclinical renal disease.

Background: Urinalysis is not routinely used in bovine medicine, and there is no evidence as to whether urine protein-to-creatinine ratio (UPC) could be used for the diagnosis of renal diseases in cattle.

Objective: The goal of the study was to determine alterations in UPCs observed with different subclinical renal diseases in clinically healthy cattle and to investigate whether UPC can efficiently differentiate cattle with and without subclinical renal pathology.

Methods: Kidney and urine samples from 57 clinically healthy adult dairy (44) and beef (13) cattle were collected after slaughter.
