Factors of non-specific immunodefence of American mink of Scandinavian selection during acclimatization to domestic conditions of growing

Abstract

The purpose. To determine the level of activity of cell (phagocytosis) and humoral (level of activity of a complement and lysozyme) factors of non-specific immunodefence of American mink of Scandinavian selection during acclimatization to domestic conditions of growing. Methods. Cell factors of non-specific immunodefence were determined according to phagocytic coefficients of blood, humoral ones – according to the level of activity in blood serum of a complement and lysozyme. Test data reduction was carried out using the method of mathematical statistics. Reliability of differences of average values was evaluated by means of Student t-test number. Results. Biochemical researches were carried out of blood cell and humoral factors of non-specific (natural) immunodefence of young animals of American mink of 4 color types (Scanbrown, Scanblack, Sapphire and Pearl) which were in conditions of acclimatization, and statistical analysis of the gained data. Conclusions. The obtained data allowed forecasting reproductive ability of American mink of Scandinavian selection in conditions of domestic farms.
