摘要

The aim of our study was to verify an efficiency of feed mixtures enriched with various portions of Cinnamomi aetheroleum for the broiler's production. In our experiment, we used final fatten type of Ross 308 broilers, as well as starter, growth and final feed mixtures. Whole fatten period was divided into three stages. The starter stage was set for 1-18 days old broilers, when the starter feed mixture (HYD-01) was fed to broilers; the growth stage was set for 19-31 days old broilers, when the growth feed mixture (HYD-02) was used and the final stage - when the final feed mixture (HYD-03) was fed to 32-38 days old broilers. The experiment consisted of one control and three trial groups. Feed mixtures for trial groups differed from the control group mixture, because they contained various portions of Cinnamomi aetheroleum (0,1; 0,05; 0,025%). At the end of the experiment, broilers gained 1738,40 g of their body weight at the 0,05% portion, 1746,40 g at the 0,1% portion and 1760,84 g at the 0,025% portion of Cinnamomi aetheroleum. The differences in body weights were not statistically significant (P>0.05).dise.
