Influence of high air temperature and sun radiation upon the structure and quality of a blood system of calf

It is ascertained that high air temperature (38-43 C), sharp sun radiation (2056-2500 kJ/m.h) affected the structure and quality of blood in investigated strains of calf. In a zone of high temperature the alternation of the morphological structure and quality of a blood system of black partly coloured and red steppe strains comes at 39-40 C being expressed in trustworthy decreasing of erythrocytes,leucocytes, haemoglobin contents, in alkaline reserve of the blood plasma reduced glutations and in increasing in oxydated glutations, in saturation of vein with oxygen. Exposition of animals under the sun at high air temperature during two hours doesn't change total quantity of blood albumen and its fractional structure. (author). 10 refs., 4 tabs
