Využití aditiv při výrobě siláží ze zavadlé píce
Sankot, Jiří
This bachelor thesis deals with many scientific technologies for the processing of wheat which will ensure its usability for a long time. And it will bring higher nutritional value of the feed compared to easier drying. This technology is silage production. The bachelor thesis characterizes the material for silage, describes the individual forages that are suitable for silage in our conditions, such as clovers, grasses and grass-clovers mixtures. Moreover, it describes the principle of silige production along with their influences. There are also described various ways of storing these conservated feeds. The main part of the thesis is devoted to silage ingredients. They are preservatives that are added to the deposited matter to improve the fermentation process and ensure the best quality of the resulting feed. The thesis presents their classification and also the difficulty associated with their use. In the last part of this work the feed analysis is described. Three samples of feed were taken from silk bales from a family farm and examined. Their analysis was carried out in the laboratory of Mendel university in Brno. The resulting values of the substances in the individual samples were different. After comparing with standard (norm) values, it was found out that the samples are comming from good quality feed, ranging from 10.17-12.32% of crude protein, 7.79% to 9.17% of ash, 3.02% to 3.36% of fat and 28,77 - 26.57% crude fiber. The result of this thesis is a proposal that recommends to use suitable silage additives for the further harvesting of wheat.

Hodnocení obsahu organických živin a epifytní mikroflóry u vybraných druhů trav
Sankot, Jiří
The work deals with the evaluation of nutrients and epiphytic microflora content in selected grass species Lolium perenne L., Phleum pratensis L., Festuca arundinaceae Schreb. and Lolium multiflorum Lam. X Festuca arundinacea Schreb. 2017 and 2018 at Vatín. The task was to determine the effect of fertilization doses by digestate, harvest year and species on organic nutrient content and epiphytic microflora. The content of nitrogenous substances, fats, fiber, ADF and NDF was evaluated from organic nutrients. The statistically significant (P <0.05) was the year for the effect on the crude protein content. Statistical significance (P <0.05) for fat content was demonstrated only in the species. For the proportion of fiber, ADF and NDF in fodder, the year of harvest, the type of fodder and the fertilizer variant had a statistically significant effect (P <0.05). The second evaluated area in forage was the epiphytic microflora. Only a fertilizer variant was statistically significant in CPM (P <0.05). The year of harvest and the fertilization variant were statistically significant (P <0.05) for BMK. The incidence of Enterobacteriaceae Enterobacteriaceae, the total number of micromycetes and yeasts was not statistically significant from any point of view. In fungi, fertilization was a statistically significant (P <0.05) variant. The effect of digestate fertilization on the amount of nutrients and microorganisms has not been evident.
