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.

Influence of different factors for economic parameters of milk production
KLEINOVÁ, Anna
Evaluation of factors, which affect the selected economic indicators of milk production in specific farm, during two years, 2007 and 2008, was the aim of the work. The composition of dietary and its optimalization and feeding technology in stable were evaluated. The contents of basic elements, which affected the realization in every month, were set from the milk production on the basis of analyses. Indicators of reproduction are mentioned then. Evaluation of chosen operational economic indicators of milk production was based on dates about costs and revenues in selected stable. Mixed feeding ration is loaded twice a day and it is compiled in advisory way according to the laboratory analysis results of feed. It was balanced with a moderate abundance of nitrogen substances and solids in production cows and with a deficit of solids in feeding ration of very pregnant non-lactating cows in both years (about 9 %). The fat and protein contents were relatively fixed, with a decline in summer months. The limit for somatic cells was exceeded once (by 3 %) and so the TVC (by 36%) in 2008. Reproduction indicators showed annual improvement with the exception of the intervening period length. There came to reduction in number of coves on the 3rd and later lactations and to decrease of their longevity thus. Their own and purchased feed took share in costs mostly (33,3% in total). In 2007 the loss per litter of sold milk arose but the income moved to positive values after including all revenues. In 2008 a profit per litter of sold mild was reached the milk production reached 3,64% and the total income increased.
