AGE DYNAMICS OF ERYTHROPOIESIS AND LEUCOPOIESIS INDICATORS AND HEMOGLOBULINE SYNTHESIS OF LAYING HENS AT LEBEDEVSKAYA FARM

Abstract

Heavy use of laying hens at the poultry farms affects poultry physiological body systems. Poultry genetics assume its intensive metabolism, but monitoring of laying hens’ physiological condition is important problem. The research explored chicken groups of 15 and showed intensive blood-forming with high number of erythrocytes, leucocytes and hemoglobuline on the 35th day. The authors observe leukocytopenia in the period of lower productivity due to lymphopoiesis depression and activation of micro and macrophagal links of immunity system. Low concentration of hemoglobuline is observed in the periods of intensive productive burden of poultry and shows poultry depletion of inner resources.
