The purpose of our research was to investigate the impact of inorganic and organic compounds of trace elements on the state of hemopoesis in dairy cows for the prophylaxis microelement insufficiency. The material for the research was the blood of experimental animals, where was determined: the number of erythrocytes, white blood cells, platelets, hemoglobin, the value of hematocrit, mean corpuscular volume (MCV), the average content of hemoglobin in erythrocyte (ICSU). The given indicators were determined on an automatic hematology analyzer type «Mythic 18 vet» (Switzerland). According to the results of hematological studies in clinically sick animals it was set oligochromemia, decrease in hematocrit values against the background of a sufficient number of erythrocytes, that helped to reduce the MCH and MCV, and also ICSU growth. These changes of hemopoesis indicate the development of hypochromic microcytaric anemia. Application of basic diet of organic and inorganic compounds of scarce microelements in the composition of feed to clinically sick dairy cows promoted the normalization of hemopoesis. It was established a better therapeutic effect in animals of second experimental group, which were fed with chelated compound of scarce microelements in the form of methionates and lysinates. At the end of the experiment, in the blood of animals of the second experimental group, was set up probable increase in a hemoglobin content, hematocrit values, МСН та MCV, and also decrease of ICSU, indicating a recovery of hemopoesis.
