Nové trendy v konzervaci objemných krmiv a jejich vliv na produkci mléka dojnic
DOUBEK, Martin
Cow's milk plays an important role in human nutrition and is one of the main products of the dairy industry. Its composition changes in response to various factors including forage. The quality of roughage is one of the important aspects for the nutrition and health of dairy cows and milk productivity itself. The aim of the diploma thesis was to assess two forages, grass hay and rye hay, and their effect on milk yield. Along with milk yield, the amount of protein and fat in milk was assessed. Feed rations at the VOD Kadov company were compared over the course of four years. Based on documented data from the company VOD Kadov, according to statistical calculations, the influence of rye haying (p 0,05) on increasing milk yield was not confirmed, and no influence on the amount of fat in milk was proven either(p 0,05). The effect of rye silage on the amount of protein in milk was proven by statistical calculation (p 0,05). The results show that feeding high-quality grass forage or high-quality rye forage has no independent effect on milk yield or fat content. Rye haylage is a suitable substitute for grass haylage in the feed ration.

Analýza kvalitativních ukazatelů silážovaných krmiv
NECHVÁTAL, Jaroslav
The aim of this thesis is to analyse chosen characteristics of silage quality. Total of 119 samples of grass silage and corn silage from the year 2018 were analysed. The quality of fermentation was analysed and silage was evaluated according to "Norma 2004", german evaluation system by Kaiser 2006 and slovakian system by Mitrík 2016. All the results were compared. 82 % of samples according to "Norma 2004", 88 % according to Kaiser and 83 % according to Mitrík were classified as the first class of fermentation. The influence of additives was also included in the evaluation of fermentation. The influence of bacterial and bacterial-enzymatic additives on the content of nutrients was observed. The results were compared with the average values of the silage of the year 2018.

The comparison of different technologies of roughage fodder in selected farm
NOVÁKOVÁ, Vladimíra
The first part of this bachelor´s work deals with describing bulky feeds. Their harvesting method, principles, production procedures and storage method are described. Here is a description of biomass preservation for the hay silage and hay. The first part marks and describes the sensory properties of hay and hay silage. The most commonly used clover and grasses are also characterized. Distribution of hay silage preparations (additives), chemical feed composition, plant biomass preservative microorganisms that are beneficial and harmful to the preservative proces. Finally, mention of corn silage and clarification of the impact of canned livestock feed. The second part of the bachelor´s work deals with self - monitoring of sensory properties and laboratory analysis on the quality of preserved matter in various ways of preserving hay silage in the silage pit, silage in parcel and hay in parcel at selected businesses. The conclision includes recommendations that could improve the quality of bulky feeds - hay silage and hay. The dry matter content of the preserved matter should be monitored. For the silage, adjust the length of the cutter and the intensity of the choking (pressing) and, where appropriate, use appropriate silage additives.

The evaluation of quality of conserved bulky fodder by different way of conservation and storage
KODADOVÁ, Lenka
The thesis in the first part deals with the characteristics of major equipment as a source of coarse fodder for preservation. Given the difficult preservability is more prominent characteristic of legumes and their importance in the cultivation of coarse fodder. It describes the significance of clover-grass mixtures in the production of coarse fodder. Methods of harvesting and conservation of grassland biomass. It is also described silage corn, the preservability, harvest methods and importance in animal nutrition. Quality coarse fodder and the factors affecting it. Influence the quality of the biomass input on preservation processes. Furthermore, also deals with the procedures and principles of the production of silage, hay and silage, preservatives and finally summarizes the deterioration of the quality of silage and forage and impact deteriorated for receiving fodder and animal performance.The second part is focused on the monitoring of sensory properties and quality assessment laboratory conserved forage preservation in different ways - loose hay, hay bales, silage pits in silage, clover silage bales and silage in silage pits on lands selected agricultural cooperative. In conclusion, the most important measures designed to improve the quality of canned food.
