Integral hematological indices of non-specific resistance of pigs as a criterion of their productive qualities under the influence of technological stress factors

The research was carried out on a purebred livestock of the main sows of the Poltava meat breed. In the blood, the amount of leukocyte formula was determined and, on the basis of the primary data, integral leukocyte indices were calculated, characterizing the nonspecific resistance of the organism. Approximate reference values of blood indices were established in the population of healthy sows of the Poltava meat breed, in which technological stress led to the development of the stage of resistance. The main load under the action of technological stress in pigs is experienced by the agranulocytic link in the blood, especially monocytes. No reliable interrelationships between blood indices and productivity indicators were established, however, a direct dependence of some indices on other links of the body's resistance was revealed.
