The article presents studies of the permissible concentrations of feed mycotoxins influence on the indicators of specific and nonspecific organism resistance of breeding stallions of Ukrainian riding, Trakehner, Westphalian and Arabian breeds bred in Ukraine. In Arabian stallions, decreased: blood serum bactericidal activity by 20.8% (p?0.001); the lysozyme blood serum activity by 2.3% (p?0.001); the phagocytosis completeness index by 32.3% (p?0.001), the relative number of lymphocytes by 23.1% (p?0.001). This caused an increase: in their total bacterial contamination of native sperm by 4079 colony-forming units per cm3 (p?0.001); thawed sperm by 10473 colony-forming units per cm3 (p?0.001); in micromycete contamination of native sperm by 36.1 colony-forming units per cm3; thawed sperm by 121.6 colony-forming units per cm3 (p?0.001) and a decrease in the biotechnological suitability of sperm by 54.2%.
