Abstract
As a result of our research, we found that the platelet hemostasis in the blood of single cows significantly varies. The most significant fluctuations we have in relation to the thrombin time of the blood of cows. This indicator increased from the third to the fifth month of coactivity in cows in 1,44 times (p <0,01), and from the sixth to the end of the eighth month, the cow health decreased by 1,57 times. The fibrinogen content, the number of platelets substantially changes in the blood of single cows. The course of physiological cohesiveness is accompanied by increased aggregative activity of platelets, fibrinogen content, thrombin time, and slowing fibrinolysis. It was found that the number of platelets in the blood of cows from the first trimester of celibacy, to the end of the third trimester increases, respectively, in 1,06. During the whole period of censure, their amount in the blood of the experimental group of animals was 1.10 times less than that of untreated cows. In single cows, the average platelet count varied within the range of 7.05-7.20 pg. In animals of the control group, these fluctuations were in the range of 7.10-7.30 pg. The content of fibrinogen in the blood of single cows from the third to the fifth month of calving increased by 1.16 times. On average, the content of fibrinogen in the blood of single cows in the second trimester was 1.84 g / l, which is 1.27 times less than this indicator in the third trimester. The average volume of platelets in the second trimester of cow density was 1.06 times more than this indicator in the third period of animal cloaca. On average, over the entire period of colonization, the average volume of platelets in the blood of experimental group cows was 7.22 pg, and in animals of the control group, 7.18 pg. The width of thrombocyte volume distribution in single cows increased to 41.79%. In untreated cows, the width of platelet distribution in volume has practically not changed throughout the research period.
