The experiments to study the influence of different doses of cadmium exceeding the maximum permissible level in the blood of laying hens. The work was carried out at the poultry farm “Tuganskaya”. Was determined serum total protein blood. Studied the content of alpha-globulins, beta-globulin, gamma globulin, hemoglobin. Studied leukocyte formula. The analysis of change of parameters of blood. Admission high doses of cadmium in the body laying hens resulted in a significant increase in the content of total protein in the serum of birds that should be seen as strengthening the protective reactions of the organism. The ratio of protein fractions of blood serum of laying hens have not undergone significant change. The study leukocyte showed that the percentage of eosinophils increased three times. Reduction of the level of segmented neutrophils is observed only at 5 and 10 MDU. Found that high doses of cadmium do not cause significant changes of the level of hemoglobin in the blood of laying hens.
