This study evaluated kidney function of healthy Santa Inês ewes, bred in São Paulo State. The aim of this paper was to establish standard reference values and stipulate value variation caused by age group factor. We determined seric and urinary levels of urea, creatinine, sodium and potassium, and urinary GGT from 128 ewes, divided into 4 groups according to age. Also urinalysis was made in 128 urine samples. No significant statistical difference was found regarding density values between all groups, although there was an increase in urea values, creatinine and sodium, and an decrease in urinary proteins and GGT in group 2, 3 and 4 older than group1. In relation to the seric parameters, there was significative statistical difference in urea and creatinine values between the groups, as an increase in urea and creatinine. Potassium decreased in the older groups 2, 3 and 4. Evaluating the results obtained for renal function, we found that the mean values of density were 1.03±0.01, pH 7.1±1.35, urea (mg/dL) 1342±1085, creatinin 42.39±23,36, total protein (g/dL) 5.61±2.88, GGT (U/L) 1.44±1.31, sodium and potassium (mmol/L) were 15.93±20.13 and 240±117 respectively. In the serum medium values were: urea (mg/dL) 32.33±19.81, creatinine 1.22±0.20, sodium and potassium (mmol/L) 145.7±8.8 and 5.5±1.30 respectively. |
