HAEMATOLOGICAL PROFILE OF COWS WITH DIFFERENT PERFORMANCE LEVEL OF PRODUCTIVITY AND THEIR CALVES UNDER ADMINISTRATION OF LIPOSOMAL DRUG
Introduction. In the article information about influence of liposomal drug with vitamins A, D3, E, lecithin, L-methionine, L-arginin, sodium selenite administrated parenterally to the cows with different level of the productivity during the last month on the morphological indices in blood of cows and calves calving from them are presented. During the last month cows are in the state of immuno deficiency related to development of foetus and preparation of organism to the synthesis of colostrums. The amount of erythrocytes and concentration of hemoglobin change at that period.
The goal of the work. Was to ascertain the effect of parenteral administration of cows in the last month on the integrity of the liposomal preparation, which includes vitamins A, D3, E, lecithin, L-methionine, L-arginine, sodium selenite on the hematological parameters of cows and their newborn calves.
Materials and methods. Blood for research was taken from the jugular vein from cows to the early feeding for 20 and 10 days before the expected births and for 5 days after calving, and from calves born at them at 5 day old age. In blood stabilized heparin, the number of erythrocytes, hemoglobin, hematocrit, and red blood cell indices were determined.
Results of research and discussion. The conducted researches have established that in blood of cows of control groups, 10 days before the expected births and on the 5th day after calving, the number of erythrocytes, hemoglobin content and the hematocrit were lower than 20 days prior to calving. Intramuscular administration of the drug to cows for 20 days to the intended births contributes to an increase in the number of erythrocytes, hemoglobin content and hematocrit values in comparison with the control animals. The introduction of vitamins A, D3, E, lecithin, L-methionine, L-arginine, and sodium selenite into cows compared with control caused a tendency to increase the MCV for 10 days before and after calving of the 5th day. In newborn calves we note the increase in the number of erythrocytes, hemoglobin and hematocrit values, than in comparison to control group calves. Introduction to cows of the liposomal drug caused a tendency to increase the filling of erythrocytes with hemoglobin and color index and decrease in the blood of calves born from them.
Conclusions and prospects for further research. Introduction of cows for 20 and 10 days to the supposed genera of vitamins A, D3, E, lecithin, L-methionine, L-arginine, sodium selenite in the form of a liposomal drug leads to an increase in the number of erythrocytes in the peripheral blood of the cows, the hemoglobin content and the size of the hematocrit. In the blood of calves derived from cows which were administered vitamins A, D3, E, lecithin, L-methionine, L-arginine, sodium selenite in the form of a liposomal drug, the number of erythrocytes, hemoglobin, hematocrit and red blood indices were higher compared to animals of control groups.
Keywords: cows, calves, erythrocytes, hemoglobin, hematocrit, blood, lecithin, L-methionine, L-arginine, vitamins.
