Resumo: | Calcium, phosphorus and creatinine were measured in serum and urine samples taken from 120 healthy Zebu cattle (Nelore) in order to establish reference values for the percent clearance ratios of calcium and phosphorus. The animals were divided in 6 groups (n=20) according to sex and age(1 to 8; 8 to 24; and from 24 months and over) to evaluate differences considering these two factors. The results were analysed using descriptive statistics and through ANOVA. The serum levels of calcium, phosphorus and creatinine were all within normal values, and the variance of urine measurements was very large. The average calcium percent clearance ratios were as follows: 0,38 ± 0,34% (male calves), 0,48 ± 0,91% (female calves), 0,65 ± 0,69% (young males), 1,45 ± 0,92% (young females), 1,53 ± 1,34% (adult males), and, 2,36 ± 1,84% (cows). Phosphorus percent clearance ratios showed 0,83 ± 1,00%, 0,38 ± 0,56% e 1,53 ± 1,39% in male calves, young and adult males, respectively, and 2,90 ± 2,84% (female calves), 0,43 ± 0,39% (young females) and 0,97 ± 0,78% (cows). These two percent clearance ratios differed related to sex and age. |

Calcium, phosphorus and creatinine were measured in serum and urine samples taken from 120 healthy Zebu cattle (Nelore) in order to establish reference values for the percent clearance ratios of calcium and phosphorus. The animals were divided in 6 groups (n=20) according to sex and age(1 to 8; 8 to 24; and from 24 months and over) to evaluate differences considering these two factors. The results were analysed using descriptive statistics and through ANOVA. The serum levels of calcium, phosphorus and creatinine were all within normal values, and the variance of urine measurements was very large. The average calcium percent clearance ratios were as follows: 0,38 ± 0,34% (male calves), 0,48 ± 0,91% (female calves), 0,65 ± 0,69% (young males), 1,45 ± 0,92% (young females), 1,53 ± 1,34% (adult males), and, 2,36 ± 1,84% (cows). Phosphorus percent clearance ratios showed 0,83 ± 1,00%, 0,38 ± 0,56% e 1,53 ± 1,39% in male calves, young and adult males, respectively, and 2,90 ± 2,84% (female calves), 0,43 ± 0,39% (young females) and 0,97 ± 0,78% (cows). These two percent clearance ratios differed related to sex and age. Com o objetivo de se estabelecerem valores de referência, e as influências do sexo e da idade sobre as excreções fracionadas urinárias de cálcio e de fósforo, estudaram-se amostras de soro sanguíneo e de urina, colhidas quase que concomitantemente, em 120 bovinos da raça Nelore, aparentemente sadios, manejados extensivamente com nutrição mineral adequada, e separados em 6 grupos experimentais (n=20) de acordo com o sexo e 3 faixas etárias assim definidas: bezerros lactentes (1 a 8 meses), novilhos (8 a 24 meses) e adultos (acima de 24 meses). Determinaram-se os níveis séricos e urinários de cálcio, fósforo e creatinina para o posterior cálculo da excreção fracionada de cálcio e fósforo, realizando-se um estudo estatístico descritivo e a análise de variância para verificação dos efeitos do sexo e da idade. Os valores obtidos para as variáveis séricas situaram-se dentro dos limites de normalidade considerados para a espécie e raça, e, as variáveis urinárias apresentaram-se com acentuada variabilidade. Quanto à excreção fracionada de cálcio observaram-se 0,38 ± 0,34% para os bezerros, 0,48 ± 0,91% para as bezerras, 0,65 ± 0,69% para os novilhos, 1,45 ± 0,92% para as novilhas, 1,53 ± 1,34% para os machos adultos, e, 2,36 ± 1,84% para as vacas. Para a excreção fracionada de fósforo detectaram-se 0,83 ± 1,00%, 0,38 ± 0,56% e 1,53 ± 1,39% em bezerros, novilhos e machos adultos, respectivamente, além de, 2,90 ± 2,84% nas bezerras, 0,43 ± 0,39% nas novilhas e 0,97 ± 0,78% nas vacas. As excreções fracionadas urinárias de ambos os elementos estudados sofreram influências do sexo e da idade.
