VALORES SÉRICOS DE CÁLCIO, FÓSFORO, SÓDIO, POTÁSSIO E PROTEÍNAS TOTAIS EM CAPRINOS FÊMEAS DA RAÇA PARDA ALPINA SERUM VALUES OF CALCIUM, PHOSPHORUS, SODIUM, POTASSIUM AND TOTAL PROTEINS SERUM LEVELS IN ALPINE DOES AND DOELINGS

SUMMARYDespite the importance of the knowledge of serumreference values of mineralogram and proteinogram, there is ashortage of studies with goats in Brazil. The objective of thisstudy was to determine and to compare the serum levels ofcalcium, phosphorus, sodium, potassium, total protein, albumin,globulin, and the albumin/globulin ratio in Parda Alpina goats atthree different ages. Thirty Parda Alpina goats raised on anintensive system were utilized. They were divided into threegroups: Group 1 – 10 young females (four months old); Group 2– 10 young adult females (18 months old); Group 3 – 10 adultlactating females (24 to 60 months old). The mean values ofcalcium, 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 serumprotein, albumin, globulin and the albumin/globulin rate themean were 6.29±0.94, 3.5±10.41, 2.78±0.95 and 1.40±0.48, forG1, 7.27±0.73, 4.92±1.06, 3.06±0.56, 1.43±0.44 for group 2 and7.14±0.84, 3.70±0.20, 3.44±0.79 and 1.14±0.30 for G3.Thestatistic analysis demonstrated influence of age on phosphorus,sodium, potassium, total protein and albumin.Key words: goats, calcium, phosphorus, sodium, potassium, totalprotein, albumin, globulin.
