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.

Základní aspekty výživy dojnic v průběhu laktace
KAZDA, Miloslav
This bachelor's thesis deals with the nutrition of dairy cows during lactation. There is characterized feeding of dairy cows in the whole meantime. Work contains of recommended feed rations with optimum amount nutrients during phases of lactacion. A brief description is also given to the nutrients, feeds and diseases caused by incorrect nutrition.

Analýza úrovně výživy a vybraných ukazatelů produkce mléka
PLACKOVÁ, Lenka
The subject of my thesis was an analysis that deals with the level of nutrition of holstein cattle, witch evaluates feeding, drinking, silage quality techniques and optimalization of the feed ration in 2017 and 2018. In 2017 the feed ration used for dairy cows contained more PDIE. In 2018 the feed ration contained lower amount of energy (6MJ NEL/ 1kg of dry matter) and NL (138,6 g NL/kg of dry matter). After comparing of these two diets for dairy cows with nutrient need, there was recommended an increase of dry matter content in feeding ration. In the milk productivity assessement, the fat and protein content, SC, total aerobic microbial count, was reviewed. The statistic shows the impact of the season of the year on the fat and protein content, SC, total aerobic microbial count in milk. From ecomomy point of view, costs per litre of selled milk was 7,69 Kč in 2017, which was lowered to 7,28 CZK per litre of selled milk. Both years was profitable, and in comparing the economy from 2017 with Czech republic average, tracked stable was more profitable 3 662 CZK per dairy cow.

Výživa dojnic v daném zemědělském podniku
PLACKOVÁ, Lenka
This thesis purpose is to evaluate level of nutrition of dairy cows Holstein cattle on the farm. Backround research was made for this topic. Claim of the study is to compare nutritional value of the feed rations with the recommended nutrient requirement ford dairy cattle. The feed ration for cows meet recommended nutrient requirements. Feed rations for the dry-off cows contain high level of nitrogenous compounds. The correction was recommanded. Further, the quality of silage roughage was assessed. Compared milk yield was lower by 615 kg milk/cow/year from the performance of Holstein cattle population in the Czech republic.

Analýza úrovně výživy v daném zemědělském podniku
PROCHÁZKOVÁ, Kamila
The diploma thesis analyses the level of nutrition of dairy cattle of a particular company and looks at factors that influences milk production. Under the operating conditions of this particular company is evaluated: the quality of bulk feed, the composition of feed diet in terms of required amounts of nutrients and energy for production levels and compared the recommended values.The thesis assesses feeding technique, housing technology and hygiene of obtaining milk. The production and health of dairy cattle breeding over the course of one year is depicted. The work also focuses on evaluating the basic economic indicators of milk production.

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.

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 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.
