Posouzení směsných krmných dávek (TMR) pro dojnice na separátoru krmiv
 Kovářová, Denisa
This diploma thesis presents the effect of a diet on milk yield and composition in dairy cows. The aim is to provide a comprehensive view on the whole issue, which means considering the forage quality, the way total mixed rations (TMR) are prepared and the way feed is utilised in cows. More than one source of information must have been used to evaluate all these factors objectively. They include milk-performance-testing data, TMR chemical analyses, separating the rations on Penn State Particle Separator and evaluating cow manure on Digestion Analyzer.

Quality roughage feed in relation to the economy of milk production
 NÁVARA, Drahoslav
The aim of this thesis was to evaluate in selected levels of nutrition and feeding of dairy cows in relation to the economy of milk production and suggest possible options for improving the profitability of milk production. They have been selected four firms, two keeping Holstein cattle and two with red coloured cattle. One company was with highest production and the second company was with average production. The aim was to assess the profitability of milk production at peak and average enterprises, especially given the quality of forage and the cost of ration. The selected companies we evaluated the composition of feed rations, especially forage quality indicators. For assessment of milk production of dairy cows were selected for the second group, or third lactation calved in the same period, and after ten pieces from each company. We also evaluated the cost of feeding dairy cows in milk and in particular the cost to produce one liter of milk a day and feed at the cost of production for the entire lactation. Selected breeds we all observed points compared with each other.
