Experiment was conducted, in which were served different levels of zinc for the cockerels Ross 308. The aim of my study was to discover, if the level 204 mg Zn/kg of feed mixture will affect the sensory characteristics of the thigh and breast muscle after 30 days of storing. From the sensory analysis, performed by the 12 evaluators, appears, that the higher level of zinc did not have a statistically significant impact on the sensory characteristics of the thigh and breast muscle in majority parameters in my study. Exception was a statistically significant difference (p < 0,05) in aroma at the thigh muscle after correction of evaluator (Zn 24 mg was evaluated 1,03 +- 0,02 and Zn 204 mg was evaluated 0,97 +- 0,02). In the breast muscle of the experimental group was relatively the best rate the juiciness - 5 % above the average. In the thigh muscle of the experimental group was relatively the best rate also the juiciness - 10 % above the average.
