HAVLÍČEK, David
The bachelor thesis Nutrition of dairy cows in the transition period deals with the nutrition of dairy cows in the peripartum period with emphasis on the prevention of metabolic disorders. The basic feeds used for the nutrition of dairy cows are described from a single-souled perspective. Characteristics of essential nutrients. Phasic nutrition and metabolic disorders caused by poor nutrition. The actual work was based on information obtained from five farms. Information was obtained on feed ration, housing method, feeding technique and incidence of metabolic disorders. From the information obtained, it can be said that most of the selected farms choose the right methods and practices in feeding dairy cows in transit. However, deficiencies were found in two holdings based on a lack of knowledge of the nutrient composition of the feed and in one case an unbalanced ration. There are no serious problems related to metabolic disorders in any of the selected holdings.

Paulíčková, Michaela
The aim of my bachelor thesis was to describe the nutrition of high-productive dairy cows during the first phase of lactation and to introduce the basic feed used in the nutrition of high-productive dairy cows. The next points of my bachelor thesis are the needs of nutrients of high-productive dairy cows and description of consequences of poor nutrition in connection with production and reproduction and with influence on metabolism. The thesis is focused on nutrition of high-productive dairy cows and changes in metabolism due to poor nutrition. At the beginning of the thesis the anatomy of the proventriculus and the ventriculus of the cattle, their physiology of digestion and their movement, rumination and production of gases are described. The next part of thesis focuses on feed used in dairy cows and is divided into grass-fed and grain-fed. After that brief nutritional characteristics during the first phase of lactation and nutritional requirements of dairy cows, such as energy, dry matter, carbohydrates, nitrogenous substances, fiber, fats, minerals and vitamins follow. The second half of thesis deals with the impact of poor nutrition on production, namely what effect have nutrients on content of individual components in milk and how dietetic errors are reflected in reproduction. The thesis also deals with metabolic disorders from the point of view of nutrition and feeding technique.

PAČESOVÁ, Kristýna
This thesis concerns about dairy cow nutrition before birth and shortly after birth. In this thesis is briefly described the physiology of digestion and food fermentation process, basic nutrition of dairy cows and individual phases of the transition period. The characteristics of the basic nutrients and used feed point out to the importance of the correct assembly of the feeding program. Unsuitable or insufficient nutrition of dairy cows in this phase leads to postpartum complications. In the consecutive parts of this thesis is described the nutrition during the dry period, the usage of feed aditives and the correct composition of feeding program in the individual stages of dairy cows gestation period. In the conclusion are summarized the main conditions for proper feeding of dairy cows and the composition of feeding program, the suitable concentration of feed energy in the individual stages of the dry period and recomended feeding of the feed aditives.
Analýza fázové výživy dojnic v daném zemědělském podniku
VONA, Barbora
The thesis deals with the analysis of the phase feeding in herds of Holstein cattle in specific operating conditions and its relation to milk yield and health of dairy cows. In the reference event to be optimized ration drystanding cows and lactating cows in comparison protocols laboratory analysis of mixed rations to standard NRC by the enterprise uses for compiling rations. The thesis was evaluated the effect of ration on milk yield and content of milk components and also affect the incidence of metabolic disorders. The aim of the thesis was to analyze the phase nutrition of dairy cows in the reporting company in relation to milk production and health, to evaluace the quality of feed rations, some feed and feeding technique. It was found that the monitored parameters do not match any breed mixed rations used in the standard, which could lead to reduced levels of production and reproduction and deterioration in health of dairy cows. It was further found that in the observed rearing occur very frequent occurrence of metabolic disturbances and fluctuations in the milk production.
