Abstract

An assessment of the features of the erythrocyte composition of the blood of Holstein black-and-white cows, which were diagnosed with follicular cystic disease as a result of gynecological medical examination based on the results of clinical rectal and ultrasound examinations, is given. Red blood cells formed from hematopoietic stem cells in the bone marrow are transformed as a result of successive stages of maturation, which are primarily controlled by the hormone erythropoietin. After full development, red blood cells lose their nucleus and then enter the circulatory system. In the bloodstream, red cells, unlike the rest, are small, flexible, biconcave. They contain hemoglobin, carry oxygen from the lungs to the periphery and carbon dioxide back. The most common diseases associated with red blood cells are anemia. It was found that the erythrocyte pool of blood is characterized by the physiological level of erythrocytes (6.10±0.11 x1012/l, Cv=1.23%), which have an optimal volume on average (43.08±1.12 fl., Cv= 8.20%). The volumetric properties of cells, estimated by the values of RDW-SD and RDW-Cv, exceed the regulatory limit by 9.19 and 14.00%, respectively, determining the hematocrit value at 26.26± 0.30% and a reduced density of saturation of red cells with hemoglobin, which corresponds to the signs of anemia.
