Deviations from optimal environmental conditions, including external conditions of keeping and feeding birds, often lead to so-called technological stresses. The effect of stress affects the cellular composition of the blood. Assessment of baseline blood parameters of chickens before stress-induced exposure in groups I and II showed that they had different gas exchange rates, which reflected on the oxygen supply of the body. Before stress (background) in the blood of two-linear chickens (group I), the number of red blood cells was 3.25 ± 0.06 1012/ , white blood cells 23.10 ± 1.02 109/l, hemoglobin 67.61 ± 2.49 g/l, average erythrocyte hemoglobin content 19.56 ± 0.52 Pg. In group II, the number of red blood cells in the peripheral blood was 3.80 ± 0.06 1012/L, white blood cells 27.10 ± 0.93 109/L, hemoglobin 83.91 ± 1.86 g/L. The effect of the stress factor in the form of a vibrational effect initiated a decrease in the concentration of red blood cells in the bloodstream of chickens, regardless of a series of studies. The cell level in hybrid birds obtained at the poultry farm decreased by 12.36% (p<0.01) compared to the background, and by 15.38% imported from Germany. In the body of chickens obtained at the poultry farm, 1 hour after exposure to the stress factor erythropoiesis stimulation was observed, compensating for the loss of red blood cells and increasing the hemoglobin concentration to 101.45 ± 2.83 g/l, as well as the value of SIT. The red blood cells and erythropoiesis organs in the body of chickens obtained at the poultry farm (group II) had a high reactivity, which allowed the body to quickly compensate for the lack of oxygen and metabolic substrates.
