Blood proteins and their informativeness in assessing the adaptive resources of chickens under technological stress

In the body of chickens, when exposed to the technological factor (the density of birds in the cage), a stress reaction developed as a result of activation of the hypathalamic-pituitary-adrenal system. The response and state of the neuroendocrine pathway is associated with the magnitude of the technological stress factor. When it is increased by 1.50 times, the maximum changes in the body of chickens are detected 4 hours after the start of the experiment. At the same time, the level of corticosterone and cortisol in the blood of birds increases by 3.42 and 2.99 times, increasing the rate of catabolic reactions in protein metabolism. Therefore, the amount of total protein in the bloodstream of chickens increases by 34.32 %, albumins by 26.74 %, urea and uric acid by 2.07 and 2.29 times, and the activity of AsAT and AlAT increases by 2.15 and 4.53 times (p
