The aim of the diploma thesis is to evaluate the content parameters of a selected group of macro and micro-elements in wheat seed (Triticum aestivum) within a group of varieties (Elixer, Vanessa, Tobak, Bombus) for feed use. Grain samples obtained in an experiment conducted within the company Rabbit Trhový Štěpánov a.s. on three different sites. In addition to the analysis of the selected group of grain qualitative parameters, the yield parameters (number of plants and cobs per area and harvested grain volume per unit area) were also evaluated. The introductory part of the thesis focuses on general information on wheat, its importance and its use. Another part of the literary research focuses on the chemical composition of the grain, the quality of the wheat and the factors affecting the quality of the wheat. The most important and most extensive part of literary research focuses on general information on minerals and their importance in animal nutrition. The methodology of the work includes the presentation of Holding Rabbit Trhový Štěpánov a.s., characteristics of the varieties and habitats on which the experiment was carried out. Furthermore, of course, it contains the soil and climatic characteristics of the sites and methods used to obtain the assessed data. The final part of the work is devoted to the results, the discussion and the conclusion in which the achieved results are evaluated and compared. It should be added that the data were obtained in the framework of the experiment in close cooperation with Rabbit Trhový Štěpánov a.s. and the level of selected elements in the grain was determined in a certified laboratory according to standardized methodologies and standard operating procedures.
