The aim of this paper is to introduce the main principles and types of feed in goat nutrition. The main focus of the work is on dairy goat nutrition and the influences on milk production. Goat milk is a raw material whose quality depends on nutrition. In addition to dairy goats, it also deals with feed composition and individual rations. As a result of this work, information on existing goat breeds, feeds suitable and unsuitable for goat nutrition and feed rations are sorted out. The composition of rations depends on several factors. The main distinction is the age of the animal. Baby goats are fed differently from adult goats. Another key factor is the physiological condition of the goats. Other factors influencing goat nutrition include the season, which determines the summer and winter rations. In order for nutrition to be comprehensive and achieve the desired results, all factors must be taken into account.

Hedvičáková, Adéla
Eating edible insects is an activity that has recently become increasingly important. In order to use edible insects safely, it is necessary to carry out, among other things, an assessment of the risks associated with consumption. This work focused on the microbiological risk assessment of edible insects. The theoretical part of the thesis provides information on the nutritional properties of edible insects and the risks associated with insect consumption. It also mentions legislation related to the inclusion of insects in food. The thesis describes the impact of insects and their consumption on the environment and presents factors that need to be further addressed in the future. The thesis provides a list of important pathogenic microorganisms. In the practical part it is possible to find a statistical evaluation of the measured values of the pathogens present in the insects and in the feed. Total counts of microorganisms, Escherichia coli, Enterobacteriaceae, moulds, Staphylococcus aureus and lactic acid bacteria were determined. The results were compared with those of studies on similar topics.

Strnadíková, Veronika
The bachelor thesis deals with the issue of nutrition of pregnant mares and is processed in the form of a literature search. At the beginning of the thesis there is an introduction to the subject, which is devoted to the characteristics of the equine sexual cycle and foaling. The aspects that influence them are described, as well as the reproductive and digestive organs, the development of the foal in the mother’s body and a description of the body score condition of the horse. Subsequently, two chapters are focused to the nutritional requirements of mares in early and late foaling and the differences between them. The last chapter describes specific types of feeds and their suitability for broodmares. Selected complete feed mixtures – granules and mueslis – are also summarised, with a description of their composition, recommended dosage and in tables is shown the content of the most important essential nutrients – digestible energy, starch, nitrogenous substances, fat, fibre, calcium, phosphorus, vitamins A and E and lysine.

Analýza úrovně výživy a vybraných kvalitativních ukazatelů produkce mléka
KAZDA, Miloslav
The diploma thesis focuses on the analysis of the nutritional level of dairy cows and its influence on selected qualitative indicators of milk production. The aim of the work is to carry out a comprehensive assessment of the impact of feed ration and its composition on the quality and quantity of milk production, with an emphasis on identifying optimal nutritional conditions for achieving the highest utility and ensuring good health and living conditions for dairy cows. In the first part of the work, a theoretical review of current knowledge about dairy cow nutrition and milk quality was carried out, focusing on energy and nutrient needs of dairy cows, quality and optimal representation of feed, individual phases of lactation, milk quality, microbiological and hygienic value of milk, and factors affecting its quality. In the second part of the work, an analysis of the nutritional level in the selected breeding was performed. Mixed feed rations and individual components contained in them were evaluated here. Furthermore, utility and qualitative indicators of milk (fat content, protein, lactose, somatic cells, and total number of microorganisms) were assessed.

Vliv výživy a prostředí na masnou užitkovost kuřecích brojlerů
HOUSKOVÁ, Lucie
The nutrition of chicken hybrids is very popular. There are already predictions that chicken meat will become one of the most consumed. The reasons may be the price, taste or composition and easy digestibility of chicken meat. Short fattening of broiler chickens and low space requirements is an indisputable advantage for breeders. The work is focused on the basic building elements important for the fattening of chicken hybrids. The practical part consists in fattening two groups of broilers in a home environment, each time in the same environment but in a different season. These results were compared with comparison groups in conventional breeding. During the experiment, it was found that when fattening in the warm season with access to the outdoors, even higher results can be achieved than in conventional breeding. On the contrary, it was proven that the group without access to the out-doors did not even achieve average gains in the colder period.

Potřeba dusíkatých látek ve výživě koní
Červínová, Monika
The bachelor thesis is focused on nitrogenous substances in horse nutrition. The work is divided into two parts, which intertwine. The first part concerns the digestion of horses, the importance of protein and non-protein nitrogenous substances and their effect on the horse's body. The specific requirements of nitrogenous substances for different categories of horses are also mentioned here. Part of the work is a summary of feeds, which also lists special protein feeds, which include, for example, spirulina, coconut flour or hemp seeds. The work also discusses possible problems with increased or decreased intake of nitrogenous substances. The second part contains my own work, the purpose was to monitor and evaluate the daily intake of nitrogenous substances in older horses who have a calm regime. For evaluation, samples of fed feed were taken and subjected to chemical analysis under the prescribed conditions to determine the nutrients contained. The results from the laboratory were recalculated and compared with the recommended needs. Based on the work, it can be said that horses receive nitrogenous substances above the recommended values.
