Plasma Uric Acid, Creatinine, And Urea Nitrogen Concentrations After Whole Blood Administration Via the Gastrointestinal Tract in Domestic Pigeons (Columba Livia)‪.‬

Abstract: To determine if blood administered to pigeons by gavage tube would simulate gastrointestinal hemorrhage in a noncarnivorous avian model, be digested in the gastrointestinal tract, and subsequently alter concentrations of plasma urea nitrogen, creatinine, or uric acid, blood from common peacocks (Pavo cristatus) was administered by gavage tube to 5 healthy domestic pigeons (Columba livia) at doses of 0.5, 1.0, 2.0, 4.0, and 8.0 ml/kg. No significant difference in plasma concentrations of urea nitrogen, creatinine, or uric acid was seen 445 hours after garage. The findings did not support or rule out the presence of gastrointestinal blood in pigeons as a model for hemorrhage in noncarnivorous avian species. Key words: gastrointestinal hemorrhage, urea nitrogen, creatinine, uric acid, avian, pigeon, Columba livia
