The development of dairy farming requires not only the availability of modern methods of treating young animals but also tracking its long-term results. Until now, calves can often have dyspepsia, which can significantly weaken the animal, sometimes leading to its death. Applicable approaches for its treatment quite effectively eliminate the main symptoms of dyspepsia, however, the state of hematological and hemostasiological parameters that are very significant in terms of prognosis in recovered calves remain unassessed. The purpose of the work: is to determine the state of activity of the main characteristics of hemostasis in calves with dyspepsia. 35-month-old Black-and-White calves cured of dyspepsia after standard treatment were examined. The control group included 28 one-month-old Black-and-White calves that had no health problems. In calves who recovered from dyspepsia, high hemostatic capabilities of platelets were noted, occurring spontaneously and in response to an inductor. These calves also had activation of blood coagulation with a weakening of the biological capabilities of fibrinolysis. It can be assumed that calves cured of dyspepsia have disorders in the hemostasis system that can impair hemocirculation and inhibit their development. This study shows that treatment options for dyspepsia need to be evaluated for their effect on platelet activity and plasma hemostasis for subsequent widespread use of treatment options that positively affect them.
