Study of factors affecting milk production
ALENKOVÁ, Kateřina
The diploma thesis deals with the study of factors that influence the production of milk in terms of nutrition. On the given farm the standart of nutrition is evaluated on the basis of the composition of the feeding diet and optimal security needs nutrients and energy in relation to the desired production and the recommended values. The feeding technique, the quality of feed composition and feed rations are evaluated on the given farm, too. The work also focused on evaluating the basic economic indicators of milk production.

Evaluation of feed rations and their effect for milk production
ROUBÍČKOVÁ, Jana
Feed rations and their influence on milk yield were assessed for the years 2010 and 2011 in working conditions on the school farm Měšice. This was mainly comparison of the basic nutrients feed rations with a recommendation. Furthermore, feeding technology, quality of silage, composition of feed rations and content of milk components were evaluated. Selected economic indicators of dairy cows were evaluated in the monitored enterprise. The results indicate that the feed rations give a good presumption for high milk yield of dairy cows. However, quality of roughages, primarily corn silage should be improved.

Evaluation of feed rations in cattle fattening
KOLÁŘ, Martin
The bachelor thesis deals with the nutrition fattening cattle and evaluates standart of nutrition on the given farm. Information on the composition of feed rations, feeding and stabling technique were obtained from the dietary study of nutrition fattening cattle. The evaluation of the feed rations was based on the needs of nutrients for the recommended values in relation to utility parameters. The work also evaluated the quality of roughage in terms of nutritional value and selected fermentation characteristics.

Nutrition of dairy cows in various stages meantime, focusing on assessing the impact of nutrition on milk production and quality
HORKÝ, Jan
This thesis examines the nutrition of dairy cows at various interim phases, with a focus on assessing the impact of nutrition on milk quality and production. At the Kojčice agricultural cooperative in the village of Krasíkovice, I monitored nutrition and production parameters in Czech pied dairy cows over the course of one year. In the first section of the work, I focused on the technique and feeding of the dairy cows, the feed ration, and assessment of the feed itself. The corn silage which they were fed was rated first class. The clover silage was rated as first, second and even third class. Consultation regarding nutrition, feed analyses and composition of daily feed rations was provided by Mikrop Čebín. I also examined the state of health of the dairy cows and calves in relation to nutrition. The average yield was 6,450 kg of milk per cow per year. I monitored the individual components of the milk and evaluated how these changed over the course of the year. The average protein content was 3.48%, while fat was 4.12%. In another section, I evaluated economic indicators of milk production. The average cost per feed day was 143.51 CZK. The average production cost per liter of milk ranged around 8.51 CZK. The average purchase price per liter of milk was 7.65 CZK.

The study of dairy cattle nutrition
ALENKOVÁ, Kateřina
The bachelor thesis deals with the nutrition of dairy cows and feeding technique and evaluates standart of nutrition on the given farm. The evaluation of the nutritional standart was based on an assessment of the needs of nutrients and energy for the recommended values in relation to utility parameters. Information on the composition of feed rations and information describing the technique of feeding were obtained from the dietary study of the Czech Pied Breed in various stages of lactation. The work also focused on evaluating the quality of forage from the perspective of selected fermentation characteristics and nutritional value.

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.

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.
