Functional parameters of trombocytic aggregation in calves of the Dutch breed for the first 10 days of life

The study was performed on 37 calves of the Dutch breed, which were obtained from healthy cows after a normal pregnancy. All calves were examined and examined for 1-2 days, 3-4 days, 5-6 days, 7-8 days and 9-10 days of their ontogenesis. In the work, biochemical, hematological and statistical research methods were applied. In the examined animals, a tendency toward inhibition of platelet aggregation in response to all applied inducers was noted in the neonatal phase. The number of platelet discocytes in the blood of the examined Dutch calves during the first 10 days of their life tended to increase. The amount of active platelet species in them decreased by 11.1 %. The number of platelet aggregates of small and large sizes in their blood also decreased during the observation period.
