Thrombocyte Aggregative Activity of Irshire Breed Calves of Milk Nutrition

Medvedev Ilya Nikolayevich

Abstract


Evaluation of blood indices and especially hemostasis elements of productive cattle has great practical meaning for biology. They are closely connected with their somatic characteristics and functioning processes of the whole organism. Clarification of their values allows to work out age-specific norms of given indices and to define clearly the beginning of hemostasiopathy coming. High productivity of  Irshire cattle and great meaning of thrombocyte activity of its cubs enduced to make evaluation of blood platelets aggregation. The aim of the work: to define peculiarities of thrombocyte activity of Irshire breed healthy calves during milk nutrition phase. There was fulfilled the investigation of 65 milk nutrition calves of Irshire breed with the usage of  hematological research methods. The most active thrombocyte aggregation was noted for adenosine diphosfate being maximum to the end of investigation. Collagenous and rhystomitzine aggregation had less intensity and similar direction what indirectly pointed at not high collagen availability and not large Willybrand’s factor concentration in it. Deaggregative thrombocyte capabilities in response to all the used inductors in case of Irshire calves of milk nutrition had tendency to growth. Not high thrombocyte activity provides cattle of this breed during growth and development optimal conditions for  blood supply of growing and ripening organs.
