Anearobic digestion plants in selected part of South Bohemia
PROCHÁZKOVÁ, Lenka
The theme of this thesis is to assess the current state of biogas business in selected parts of southern Bohemia and the possibilities for its further development. Further processed economy on the example of a selected company and undertake structured interviews with operators of biogas plants. The first research part handles the issue of biomass, biogas, their preparation - what all have to be careful before and during construction, the legislation itsef and its implementation. In the second part analyzes the economics of selected company, which operates the biogas plant. Everything is monitored from the beginning of construction in 2012 until 2016. Each year are evaluated both financially and in terms of input material consumed. The last section is devoted to the questionnaire controlled interview with executives of three companies that operate biogas plant. The questionnaire consists of three parts - before the construction, during the implementation of biogas plants and biogas into the future of business.

The comparison of different technologies of bulky fodder crop conservation
PAVLÍK, Václav
This bachelor thesis deals with comparison of various technologies for roughages preservation. Roughages represent a great part of basic ration for farm animals. The introductory part of this thesis deals with the importance of preservation itself and the basic ways of roughages preservation. Several processes, principles and technologies of preservation by dry curing process and silage are also described here. Further, the thesis lists advantages and disadvantages of individual preservation technologies and silage additives. The second part of the thesis is focused on observing and sensory evaluation of fodder quality within various ways of preservation - silage in silage mangers, silage in bags, wrapped silage bays and bales of hay. Are designed appropriate progresses preservation bulky forage for farm animals in a companies with different volume of production. As suitable way of conservation it´s a conservation by silage in a sac and in round packaging or by high pressure stamping hay into a round packages.

Aditivní látky a jejich vliv na kvalitu siláží
ŠEJBOVÁ, Tereza
The aim tehsesis propose theim position of aditives based on the compilation work. This work, inter alia deals with silage and use of aditives on the quality of silage. The introductory part focuses on theim portance of conservation of livestock feed. Another part deals with the ensiling process with a focus on fermentation and composition of microorganisms that affet the course of the fermentation, either positively or negatively. Theim portant part is the distribution of additives, which are used in silage. There is an emphasis on the quality of these products and their impact on the quality silage. Then extsection identifies the aspects of evaluating the quality of silage. Finally, the work focuses on the use of additives.

Konzervace kukuřice silážováním
BROŽ, Petr
Modern livestock production is in many ways a progressive discipline, which is characterized in that it blends several seemingly unrelated industries. One of the most important nutrition and feed livestock. With the development of the cultivation of maize (Zea mays), and the need for its preservation, it was necessary to develop a methodology proper ensiling. This practice establishes the correct principles for the production of high-quality, nutritional value and harmless silage. It already belongs to the selection of the optimal hybrid, suitable agronomic measures during cultivation, build a functional and efficient silage lines, selection and application of additives, proper layering and ramming masses and responsible handling of ready-made food, including a ration.

Growing of corn and changes in technology depending on the direction of production
KŮRKA, Pavel
Bachelor thesis deals with the cultivation of maize. Describes the development of maize cultivation from history to the present time. The basic division is growing crops for grain and silage. Also important is choosing the right hybrids. Provides information about changes in technology and equipment needed for corn growers. And changes technology depending on the direction of production. Work is processed trought literature review on the basis of information from books, publications and other articles.

Vliv kvality siláží a složení směsné krmné dávky pro dojnice na kvalitu mléka
Hrazdirová, Vladěna
This bachelor thesis deals with cattle bulk feed and its effekts on raw milk. Stock feeding not only influences the amount and constitution of produced milk, but it also impacts the health state of dairy cattle, that along with a suitable feed plays a key role in producing high quality milk and consecutive dairy products. A signifiant portion of milk components depem as well on the physiological processes that take place in ventrikle and proventriculi. The objectvice of this surfy was to point aut the major effects of feeding and diseases, caused by an inappropriate composition of nutrients on the quality of obtained milk.

Ennergtic heftiness of storing haylage and silage into the silage bags
JANOUŠEK, Šimon
My thesis focuses on discovering power heftiness of storing harvested material into the silage bags. The theoretical part heeds the basic needs of the procedure of preservative process during preservation of fodder plants. There is a brief characteristic of most widely used technological procedures of storing harvested material into the storage area, structure of technological units, characteristic of individual means of mechanization for harvest and subsequent storage of solid pasturage. The practical part is focused on measuring of power heftiness of storing haylage and silage into the silage bags. There is also comparison of agricultural limits of power drain to other methods of stored material into the storage area.

Conservation of corn silage
KŠANDA, Martin
This bachelor thesis deals with using of maize for production of silage that has a high potential and that are an irreplaceable part of a cattle nutrition. The introductory part focuses on the origin, characteristics and description of individual parts of plants. This chapter is followed by a mention of the posibilities and use of silage hybrids of maize. Following chapter describes the procedure of conservation and fermentation. The thesis also mentions microorganisms that have a positive as well as negative influence on the whole procedure. An interesting chapter is an introduction ofa silage additives. The conclusion is about constructions that are used for silage. One of the most important parts of a thesis is a technological description of the procedure of silage, together with harvest methods and factors, which are of great importance for a final product- a good quality and eneregy- rich feed, that a corn silage undoubtedly is.

The use of cereals for biogas production
FENCL, Lukáš
In these days, renewable resources is a very current topic which also includes biogas production in agricultural biogas stations. Some of the main raw materials used to produce biogas are cereals, which we will be focusing on in this thesis. The use of cereals for energetic purposes results in decreasing the state of non-renewable resources in nature. The aim of this bachelor thesis is to summarise findings of various possibilities for utilisation of cereals to produce biogas and compare cereals of the 1st and 2nd group. Describe biogas and biogas station linked with it as such, we used biogas station in company ZS Kozojedy, a.s. Cereals are split into two groups and in order to produce biogas you may use both of these groups. Bachelor thesis is mainly focused on two main crops which are now a days very important for production of biogas. Included between these two crops also are: firstly maize, which has worldwide representation in crops grown mainly to make silage; and secondly rye which is more part of new crops from which silage is already being made.
