The aim of this diploma thesis was to verify the effectiveness of phytogenic additives in utility parameters of poultry.The experimental study was conducted at the research station of the company Delacon Research Station PNRC s.r.o. in Stošíkovice on Louce.The experiment was carried out with little roosters hybrids ROSS 308. The fattening took 42 days and the three-phase feeding BR 1, BR 2 BR 3 was applied. Phytogenic additives were added to all kinds of feed mixtures. Given that this is a primary research of a private company, it is not known the exact structure of the used additives, which the company protects as its know-how. Additives were based on saponins in combination with other substances of phytogenic origin. During the process of fattening, the utility parameters of the experimental groups were monitored, which were then compared to the control group.Experimental groups showed a positive effect in several utility parameters at particular periods, statistically conclusive positive results were obtained only in the feed conversion in one experimental group during the 29th - 42nd day of fattening and in three experimental groups in whole fattening evaluation from 1. - 42nd day.
