FEATURES OF HEMATOLOGICAL AND BIOCHEMICAL INDICATORS OF THE BLOOD IN THE BODY OF DECORATIVE BIRDS

Abstract

The blood of parrots, like other agricultural birds, contains red blood cells, platelets, leukocytes. Some hematological parameters such as hemoglobin, hematocrit, and average red blood cell volume are different from those in chickens.

Changes in the nonspecific protection indicators of granulocytes and agranulocytes indicate the effect on the poultry organism of infectious agents (bacteria, viruses, fungi). An increase in the number of leukocytes (leukocytosis), in addition to infection, may be indicative of neoplasms, lesions and necrosis of the tissues of organs. Physiologically insignificant increase in the level of leukocytes is noted in the body of young poultry. A decrease in the number of leukocytes (leukopenia) is a symptom of infections and toxic substances.

Changes in the biochemical parameters of blood indicate a violation of metabolic processes in the body of the bird, the action of chemical, toxic and infectious (bacteria, viruses) agents, and also allows to evaluate the functioning of internal organs. The cells of the organs and tissues of the body of birds contain specific enzymes, and when they are damaged, these biologically active substances are released into the blood. Deviation of the level of enzymes, macro- and microelements in the blood indicates gross violations of the structure of vital organs and tissues.
