[The effect of colostral immunoglobulins on hematological and biochemical indicators in calves]

Haematological values (haemoglobin concentration, haematocrit, erythrocyte and leucocyte number) and the levels of biochemical parameters (plasma concentrations of magnesium, zinc and copper) were studied in dependence on the level of immunoglobulins in calves in the early postnatal period. As a parameter of colostrum intake and quality the immunoglobulin level in blood serum was chosen, according to which the calves (n = 300), aged from two to six days, were divided into four groups. A relationship between the colostrum intake, or the immunoglobulin level in blood serum, and the magnesium concentration in blood plasma was observed. The magnesium level in plasma was in correlation with the Ig level in the blood serum of calves. As far as the other studied blood parameters are concerned, no statistically significant differences were proved in the calves aged two to six days.
