GRUBEROVA, H. A., Influence of yeast supplement on parameters digestibili-ty nutrients by sport horses. Diploma Thesis, Mendel university in Brno, 2018, 74 p. The aim of this diploma theses was the determination of digestibility of nutrients af-ter the addition of yeast (lyophilized Saccharomyces cerevisiae) into the horse feed. The objective was determining the digestibility of dry matter, crude protein, crude fat, crude fibre, N-free matter, raw ash, and energy of daily ration with or without supplement of yeast Saccharomyces cerevisiae to diets for horses. Nine horses were involved into the experiment. According to the valid rules for bal-ance experiment for horses during three balance period. From laboratory analysis daily ration and feeces we are determination digestibility of nutrients, dry matter 71,25 ± 4,86 %, coefficient digestibility of crude protein 85,47 % ± 3,32 %, coefficient of digestibili-ty of crude fat 69,89 % ± 6,51 %, coefficient digestibility of crude fibre 33,32 % ± 9,71 %, coefficient digestibility of N-free matter 79,84 % ± 4,05 % and coefficient digestibi-lity of energy 74,58 % ± 3,81 %. The supplementation of yeasts into diets for horses does not influence on the intake and digestibility organic matter and the energy.

Zhodnocení krmných aditiv pro koně dostupných na českém trhu
Gruberová, Hana Abigail
Currently we see on the market a lot of various kind of feed additives from many manufacturers. Orientation in product composition, quality and suitability is difficult and can be compared from different perspectives. I described in this thesis the distribution of nutrients and vitamins and minerals overview from the perspective of horse nutrition. Vitamins and minerals are a major part of most vitamin-mineral premixes available on the Czech market. I compared in the sheet the obtained information for the purposes, I compiled a table that allows you to compare different products. I developed and entered into the table feeding norm and simple ration. We can determine the needed and required vitamins and minerals from the resulting tables (ie. the average weight of a warm-blooded horse type) over restorative ration and possible supplementation of vitamin-mineral premixes and complete mixes. Im not pursuing in this thesis enzymes, probiotics, prebiotics, antibiotic growth promoters and growth stimulators without added antibiotics, because these substances are not common in premixes and are not usuallz given to the horses.
