Blood study of moose (Alces alce ) of the Losiny Ostrov National Park

Elk (Alces) is the main representative of the deer family. The real habitat is quite wide and extends to the Eurasian and North American continents. Given the poorly studied nature of the types of hematological trends and unspecified reference intervals, the study and replenishment of the information base is relevant. The data obtained allow us to improve our understanding of the background losses of the human body and optimize approaches to preserving this species as native specimens of our planet.
The article presents the results of a hematological study of the peripheral blood of elks (Alces Alces Alces). They define a general clinical, integral and morphological assessment of the blood, which reflects the adaptive state of the body to the multifactorial influence of the environment in a metropolis. To collect blood, the elks were subjected to pharmacological immobilization.
The study revealed the following morphometric and integral parameters: absolute red blood cell count - 7.6 x 1012/l and sedimentation rate - 34.5 mm/hour, platelets - 450.3 x 109/l, hemoglobin - 12.5 g/dl, hematocrit - 33.6%; color index - 0.5 U, average volume of red blood cell - 47.8 fl, middle half - 34.3 g/dl and average content - 16.5 pg of hemoglobin in red blood cell. Minor anisocytosis up to 71%/RBC, moderate poikilocytosis up to 50%/RBC and anisochromia in 71.44%/RBC were noted. Microcytic hypochromic anemic syndrome. The total number of leukocytes is on average 4.4 x109 /l. When determining neutrophils - 2.14, absolute monocytes - 0.8, eosinophils - 0.13 and lymphocytes - 0.72×109 /l. The tension of adaptive and sanogenetic reserves of the body, the autoimmune nature of endogenous intoxication of moderate degree were established (Krebs Index (IK - 1.69; IS - 1.78; LII (r, m) - 1.21; RON - 0.7; ILG - 6). ,16; Garkali Index (LI) - 0.75; ISLM - 1.68; 27.06).
Hematological parameters and integral indices, including intoxication, have diagnostic innovation in the conditions of adaptive and sanogenetic conditions of the moose (Alces Alces) body and allow early assessment and diagnosis of the development of the inflammatory process.
