Leucocyte profile of blood in cows with purulent-necrotic lesions in the hoof area

The work is devoted to the study of the leukocyte profile of blood in animals with orthopedic diseases. Experimental studies were conducted at the Khmelevskoye LLC, Melekessky District, Ulyanovsk Region, during orthopedic medical examination. To achieve the goal set in the work, we formed 2 groups of animals: Group 1 - clinically healthy cows (n = 5). Group 2 - orthopedic diseases (n = 5). Blood samples were taken from all animals before morning feeding, the concentration of leukocytes was studied in the SIMPSON veterinary clinic (Samara) using a Mindray BC-30Vet hematological veterinary analyzer. The leukocyte formula of cattle blood was determined using Philipson staining, and based on the obtained data on the “white blood” parameters, the leukocyte indices were calculated: Garkavi Index, Breddeck Index, Krebs Index, Leukocyte Intoxication Index according to Ya.Ya. Kalf-Kalif, Leukocyte Intoxication Index according to V.K. Ostrovsky, Blood Leukocyte Shift Index, Lymphocyte-Granulocyte Index, Allergization Index according to V.S. Tikhonchuk, Neutrophil and Monocyte Ratio Index according to Zh.G. Mustafina.
