THE STATUS OF MORPHOLOGICAL INDICATORS OF BLOOD OF COWS AT HYPOCOBALTOSIS, METHOD OF CORRECTION
At the beginning of the experiment, with a decrease in the level of cobalt in the blood of cows (the period of separation), changes were found indicating the development of anemia, leukopenia in combination with eosinophilia, relative neutropenia, lymphopenia and monocytopenia. Microscopy of stained smears showed that most of the red blood cells were non-specific in shape, of different sizes, with a predominance of large cells with an expanded area of illumination in the center. When evaluating erythrocyte indices, a decrease in hematocrit was found, confirming the development of anemic syndrome. At the same time, the average size of the red blood cell exceeded the average limits of the reference values, which is typical for the predominance of blast-type red blood cells in the circulating blood. The average concentration of hemoglobin in the red blood cell was lower than the average value, which confirms a decrease in the intensity of blood pigment synthesis in animals with hypocobaltosis. The width of the distribution of red blood cells varied from 23.0 to 28.6 %. In the treatment of cows with hypocobaltosis, the use of uberin has a positive therapeutic effect.
