HEMATOLOGICAL PROFILE IN THE YAKUT BREED HORSES AND PRILENSKOYE

Abstract

The morpho-physiological indicators of the peripheral blood of the Yakut and Prilensk horses were studied depending on their habitat in different climatic zones of Yakutia. Studies were conducted in the farms of Ust-Aldan, Nyurbinsky and Khangalassky districts of the Republic of Sakha (Yakutia). In each selected farm, research groups were selected from among clinically healthy horses with 50 heads each at the age of 5-6 years based on the principle of analogues. The studies were covered two seasons of the year: in winter and spring, under usual conditions of horses. As a result of the research, was found a significant difference in the hemoglobin level in the blood of horses within the Yakut breed depending on their territorial affiliation P (M1-M2) <0.05 (123.0 ± 0.25 g / l; 114 ± 0.38 g / l). A higher level of erythrocyte counts in peripheral blood was observed in Yakut breed horses in the Nyurbinsky district (7.02 ± 0.72 million / μl.), and the lowest - in horses of the same breed in the Ust-Aldan region (6.2 ± 0.31 million mcl). There is no significant difference between horse breeds.The results of morphophysiological studies of peripheral blood indicate the specificity of the adaptive response of the body of the Yakut and Prilensk horse breeds to extremely low temperatures, poor nutrition in the winter, lack of food in the spring are characterized by seasonal regulation of protein metabolism.
