Abstract

The article considers the issues of the peculiarities of how the technological stress influences the indicators of red blood cells in pigs. Clinically healthy animals were selected at the stage of mobilization of the development of stress response according to the principle of pairs of analogues: group I - breeding boars, group II - breeding sows. The oxygen budget of the body, determined by the indicators of red blood cells, during the development of a stress reaction in breeding pigs of “mature age” is also determined by their gender. Boars had average values of erythrocytes and hemoglobin in reference values, but the degree of saturation of erythrocytes with hemoglobin was lower than normal and lower than that of sows. This may indicate that boars experience a greater shortage of oxygen supply to the tissues. Sows, in general, are more stress-resistent, as evidenced by the values of the ratio of lymphocytes and neutrophils, as well as their erythrocyte indicators. They differed from boars by a significantly lower level of erythrocytes and the reference level of hemoglobin in all examined individuals. In sows, the indicator of erythrocyte saturation with hemoglobin was significantly higher than in boars.
