Despite the importance of the knowledge of serum reference values of mineralogram and proteinogram, there is a shortage of studies with goats in Brazil. The objective of this study was to determine and to compare the serum levels of calcium, phosphorus, sodium, potassium, total protein, albumin, globulin, and the albumin/globulin ratio in Parda Alpina goats at three different ages. Thirty Parda Alpina goats raised on an intensive system were utilized. They were divided into three groups: Group 1 - 10 young females (four months old); Group 2 - 10 young adult females (18 months old); Group 3 - 10 adult lactating females (24 to 60 months old). The mean values of calcium, phosphorus, sodium and potassium were 10.10± 1.70, 10.13± 2.04, 151± 3.30 and 5.16± 0.41 for G1, 10.36± 0.94, 7.49± 1.34, 145.9± 3.35 and 4.56± 0.48 for group 2 and 9.47± 1.45, 5.90± 1.21, 153.3± 5.17 and 4.20± 0.55 for G3. For total serum protein, albumin, globulin and the albumin/globulin rate the mean were 6.29± 0.94, 3.5± 10.41, 2.78± 0.95 and 1.40± 0.48, for G1, 7.27± 0.73, 4.92± 1.06, 3.06± 0.56, 1.43± 0.44 for group 2 and 7.14± 0.84, 3.70± 0.20, 3.44± 0.79 and 1.14± 0.30 for G3.The statistic analysis demonstrated influence of age on phosphorus, sodium, potassium, total protein and albumin.
