INFLUENCE OF IMMUNOSTIMULATORS ON MORPHOLOGICAL AND IMMUNOBIOCHEMICAL PARAMETERS OF BLOOD OF PREGNANT COWS AND NEWBORN CALVES
The article reflects the results of changes in the biochemical and morphological parameters of blood, as well as the content of total protein and its fractions under the influence of immunostimulators in black-and-white cows and calves obtained from them. The aim of the study was to study the effect of the immunostimulators “Recombinant Bovine Interferon” and “Immunate” on the morphological and immunobiochemical blood parameters of pregnant cows and newborn calves. Studies were conducted on 45 pregnant cows divided into three groups based on the principle of analogues, and, subsequently, on 45 calves obtained from mother cows and divided into nine groups. Maternal cows during pregnancy and newborn calves were given immunostimulators in various combinations. In the blood of cows of the experimental groups, five days before calving, higher indicators of red blood cells and hemoglobin were registered in comparison with the control indicators. Also, in experimental cows, the content of total protein and globulins exceeded the indicators of the control group. Calves received from cows immunostimulated with “Recombinant Bovine Interferon” and who were given “Immunate” after birth had the smallest decrease in the number of red blood cells and white blood cells on the tenth day. After drinking colostrum in calves of experimental groups, the total amount of protein increased, especially there was an increase in the gamma-globulin fraction. For all periods of the study, the content of immunoglobulins A, M, G in the blood serum of calves of the control group was lower than that of calves of the experimental groups. The maximum difference between these indicators and the control was found in animals of the sixth and ninth groups.
