MATVIICHUK D. Vascular-platelet hemostasis in cows during calving and its correction

The study of hemostasis and blood properties of beef cows made it possible to generalize and substantiate their dynamics during the process of carrying a fetus. Their features in the section of three trimesters of pregnancy have been revealed. Their differences during pregnancy and after pregnancy have been determined. Blood rheology and hemostasis indicators were revealed depending on the duration of the third period of pregnancy, i.e. fetus removal. A scheme for their correction has been developed and proposed. The first stage included the study of the specified indicators and processes before pregnancy. During three periods of research and for its entire period (for 9 months). Experimental and control groups of animals were formed under the conditions of Vitalia SFG. The introduction of research results into production is a research and production experiment, according to the general scheme of which, 50 calving cows were used, which were divided into two groups: correction was carried out, experimental (40 cows) and control (10 cows). In the research and production experiment, the cost of additional production at the expense of the calves of the research groups is from 450 to 750 UAH. In general, profit from UAH 43,90 to UAH 73,17 was obtained. per animal of the research group.
