title: [Peroral administration of zinc sulfate to pregnant cows and its effect on selected metabolic indicators in the dam-calf lineage].
abstract: A comparative trial was conducted with the oral administration of zinc sulphate to pregnant cows and heifers aimed at influencing the selected metabolic parameters in the dam-calf line. The total daily ZnSO4.7H2O dose of 3 g (680 mg Zn++) was given to dry standing cows and heifers for 35 days on an average (15-65) before the expected date of calving. The breeding conditions in the stock were problematic: losses of calves suffered in the last half-a-year period were higher than 30% of born calves; the main causes of this high mortality were coli-septicaemia and coli-enteritis. As compared with the eight control animals, the experimental cows and heifers (12 head) exhibited a transient increase in zincaemia, followed by a tendency to proteinaemia; aspartate aminotransferase activity increased, total immunoglobulins remained unchanged, and decreases were recorded in the activities of alanine aminotransferase, alkaline phosphatase, creatine phosphokinase and aldolase. On the other hand, the concentration of total bilirubin tended to increase. In 77% of the cows and first-calvers of the experimental group the quality of colostrum complied with the standard; in the case of the control animals this proportion was 83%. Significant zincaemia occurred in the calves of the experimental cows between the first and 14th day of their age; no differences from the control calves were recorded in immunoglobulinaemia, proteinaemia, albuminaemia and in the activities of alanine aminotransferase and creatine phosphokinase. On the other hand, aspartate aminotransferase activity tended to grow and alkaline phosphatase activity tended to sink. Neonatal hyperbilirubinaemia disappeared within the first 14 days of age in both the experimental and the control calves. The results failed to show clearly that the intention to increase the values of the studied parameters of immunopoiesis was met.
