1 st WorkshopXIII International Feed Technology SymposiumObtained results were processed statistically according to method by [21].RESULTS AND DISCUSSIONThe possibility for introduction of aroma citrus fennel into nutrition of fattening chickenswas investigated.Obtained results of average body masses obtained on 17 th , 39 th and 46 th day are presentedin table 2. Introduction of 300 g/t of Citrus Fennel aroma into mixture causedstatistically significant (P
1 st WorkshopXIII International Feed Technology SymposiumSimilar to gain, also daily food consumption during initial, the second and the thirdfattening period was higher by 13.9%, 1.5% and 1.5%, respectively (Table 3) in trialgroup fed mixtures based on Citrus Fennel. During the entire trial, addition of CitrusFennel in the experimental group improved food consumption by 2.4% compared to thecontrol group of chickens.Table 3.

During the second and thirdfattening period, feed conversion ratio had improved, so for entire trial period foodconsumption for 1 kg of growth improved with the adding of Citrus Fennel by 3.1%compared to the control group fed mixtures without investigated additive.Table 4.
