Humic acids were described as prospective compounds utilized to ensure sufficient quantity
of food for human population at a high economic profitability of agriculture production
and moreover protection of the environment. In feeding trial on broiler chickens the
effects of humic acids as feeding additives on production parameters and activities of
antioxidant enzymes in blood were tested. 14 800 chickens from treatment group were
compared to 142000 untouched control chickens. Treatment group showed significant
decrease in mortality (0.95%) in comparison to control (3.5%), better of feed conversion
(13%) and faster growth. Comparison of the results from blood sampling on days 14 and
35 of treatment period showed enhanced cooperation of antioxidant enzymes as glutathione
peroxidase, glutathione reductase, superoxiddismutase leading to overall lower
levels of substrate peroxidation. Addition of humic acids to feed in treatment group in
comparison to control showed better protection against radical generation.
