FIELD: agriculture, fodder production.
SUBSTANCE: the present innovation deals with manufacturing fodder additives. The suggested fodder additive contains selenium-modified hydrolyzate of connective-tissue protein elastin being adsorbed upon zeolite at the ratio of 2:1, correspondingly, moreover, for modifying elastin hydrolyzate one should apply sodium selenite at 50-200 mcg selenium/g hydrolyzate. The innovation enables to obtain intoxic fodder additive and increase selenium digestibility.
EFFECT: higher efficiency.
