[Reference values in the cerebrospinal fluid of calves between four and eight weeks of age]

Reference values for the following parameters were established in the cerebrospinal fluid of 27 calves between four and eight weeks of age: specific weight, protein concentration, erythrocyte count, total leucocyte count with cell differentiation, creatin kinase activity, glucose and sodium. If possible, the findings were compared with those of other authors in calves and adult bovines. With 24.3 cells per microliter the 90% quantile of the total leucocyte count was seated significantly above comparable values for adult bovines. Hence, in individual cases markedly higher leucocyte counts can be expected in the cerebrospinal fluid of calves. In agreement with other authors, the protein concentration in calves was lower than in adult bovines. The reference range for creatin kinase activity was increased whereas the one for sodium was only slightly increased compared to earlier investigations in calves and in adult bovines.
