The purpose of the research is to evaluate the effectiveness of bulls-producers feeding with biologically active food

supplements with antioxidant properties derived from peat as to the quality of sperm. The study was carried out in 2016 by

the method of group-periods (preliminary, experimental and final) in specialized breeding enterprises of the Kirov region. It

was formed 2 analogous groups of animals - experimental and control one - 10 animals each. In the experimental period of

30 days the animals of the experimental group were fed with the studied Supplement containing 8.3% of humic and 24.7%

fulvic acids in an amount of 50 ml per head per day mixed with feed. In the preliminary and final periods of 60 days each,

the Supplement is not used. The studies established that the complex of substances with antioxidant properties that are in-

cluded in the supplements had a positive effect in maintaining the high quality of the sperm of animals. In the experimental

period, the concentration of sperm in the ejaculate of bulls that received feed additive increased by 0.07 billion/ml or 7.4%;

in the final period by 0.08 billion/ml or 8.4% (p<0.05) in comparison with the prior period. In bulls of control group this

indicator had no significant differences. The spermicidal activity in animals of the experimental group in the experimental

period increased by 0.56 points or 8.7% (p<0.05) for the preliminary period while in control bulls only by 0.3 points or

4.8%. Biologically active substances in the additive, acting on the body of breeding bulls, optimized metabolic processes

in sperm thereby increasing their resistance to cryopreservation; as a result, the number of culled frozen sperm doses for

the observation period in the experimental group animals, in average per bull was 44.3 dose or 60.5% less than in control.

Key words:

antioxidants, bulls, feeding, biologically active additive, reproductive function.
