The concept evaluation of dairy cattle nutrition
ROUBÍČKOVÁ, Jana
Bachelor thesis gives a comprehensive overview of the dairy cow nutrition and assesses the system of nutrition and feeding in relation to milk production. The main part is devoted to the basics of dairy cow nutrition, the main nutrient requirements and composition of feed diets. There was assessed composition of feed rations for the year 2010 in working conditions on the School farm Měšice. The recommendations were designed to improve the nutrition level on the farm on the based data.

The concept evaluation of horse nutrition
SEDLÁKOVÁ, Kristýna
The paper evaluates the system of feeding and nutrition of horses. It deals with the importance and energy requirement, the importance of individual nutrients, minerals and vitamins, and technology feed horses, which is aimed at sports and feeding of older horses. The thesis focuses on the evaluation representation of nutrients in the rations for horses and their comparison with the standard nutrient for horses. The monitored parameters are: dry matter, digestible energy, crude protein, digestible crude protein, fiber, calcium and phosphorus. The need for those nutrients in rations met. The film shows an increased proportion of calcium, phosphorus, and digestible crude protein, which is still with in tolerance.

Comparative foraging study of selected species family Cebidea - "nails monkeys" in the ZOO Plzeň.
BROŽOVÁ, Alena
The main objective of this study was investigation of accurate diet portions and observing food preferences of callitrichids. The work was executed in the Pilsen ZOO in 40 days between March 2010 and September 2010. The studied species were: Leontopithecus chrysomelas, Saguinus imperator, Saguinus oedipus, Callithrix jacchus, Saguinus midas and Saguinus fuscicollis. The aim was to find out the actual nutrition values of the diet and to determine preferences for given fruits. The results were compared with recommended values. The amount of fat, proteins, fiber, calcium and phosphorus in the diet of callitrichids were compared with the recommended quantities of diet. Little diferences from recommended nutrition values were found in some cases without major impact on the animal health. The second part of the research was focused on the food preferences for five types of fruit. The results show that callitrichids prefer grapes and banana.

Nutrition and feeding influence for economic parameters of milk production
DOLEŽAL, Tomáš
The thesis aims to evaluate the influence of nutrition and feed on the economic indexes of milk production in the Agriculture Cooperative of Borovany. The first part of the thesis focuses on the basic aspects of dairy cattle breeding including the physiological processing affecting their efficiency. The second part concentrates on preparing feed rations, describing the crucial elements specifying the level of milk yield and a particular way of feeding technique. The main factors influencing the economic indexes of milk production are desribed and analyzed in the pivotal part of the thesis, primarily the feed costs and quality. The objective of the thesis is to find out in what way the feed quality can affect the economic indexes of milk production in the observed years of 2007 and 2008.

The high milk productive cows nutrition inrespect of milk blood and urine componds content
CHVALOVÁ, Růžena
The aim was to assess the level of nutrition of dairy cows with regard to the parameters of milk in the farm economy and appreciation of farming. Nutrition cows was assessed on the basis of rations compiled a profile of the ruminal sample cows. Content of milk constituents were identified from the analysis supplied by dairy and compared with the standard. Evaluation of economics of farming has been carried out both on the total cost and sales business. Cows were fed the same year pooled rate. The basis of each mix was preserved voluminous fodder own production. According to the spreadsheet from the ration nutrient differed slightly, but without significant differences. Content of milk constituents in both years was relatively balanced and meet the standards. In the evaluation of protein content and urea were observed in compound doses deficit protein or energy. When comparing the economics of farming, production of milk in 2009 suffered a loss due to low purchasing prices of milk.

Nutrition and feeding influence in relation to milk production of dairy cows
BARTUŠKA, Václav
The assessment of the level of nutrition of dairy cattle in relation to their milk pruduction was carried out under operating conditions. The focus was on the quality of the roughage feed, the feeding technique, the contents of the diet and the supply of nutrients. On the basis of operating and economic indicators, the milk production costs as well as an overall evaluation summing the individual observed periods have been calculated. The results of the observation of the level of nutrition over a three-year period indicate that the feed rations are prepared according to the optimal standards. In the observed periods, first quality* corn silage and first or second quality** corn silage was always used. The average efficiency of a cow reached 7 000 kg of milk per year. The average cost of one litre of thus produced milk was 9,30 CZK in an average day, and the average sum of money needed came in at 138,37 CZK.
