Cortisol and his relationships with leukocytes in the organism of boar-producers

The effect of the rock on the morphological composition of the blood was experimentally studied. The object of the study was boars of the breed Duroc, Yorkshire and Landrace. It has been established that the age and breed of animals determine the nature and direction of changes in the blood within the limits of the physiological norm. The number of leukocytes in the body of 3-year-old Durks, Yorkshire and landraces is reduced, as compared with 1-year-olds, by 8.32; 15.51 (p<0.05) and 17.81% (p<0.05). In the leukogram, the number of eosinophils and lymphocytes increases: in 40% and 8.05%, in Yorkshire - by 19.05 and 10.56%, in landrace - by 25.54 and 25.94%, respectively. This occurs against the background of an open number of segmented neutrophils and monocytes. The number of cells in the Duroc leukogram decreases by 13.13 and 16.29%, Yorkshire 9.57 and 32.78%, landraces by 25.69 and 15.25%. The concentration of cortisol depends on the breed (the maximum level of hormones in the blood of Yorkshire (78...
