Zvýšení produktivity práce v prostředí velkovýroby mléka v ZD Ločenice
KAMÍROVÁ, Anna
This thesis proposes three variants of the reconstruction of the collective farm in Ločenice. Each variant calculates and compares changes of the profit under certain circumstances in current business's state. It was possible to calculate the profit only for the animal sector of the business according to collected data, which is 4 987 215 CZK/year. The A variant depicts the reconstruction of the collective farm using a new robotic milking system. In addition, there is an increase in the production of milk by A a) 5 % in this variant. The profit is then 1 833 818 CZK/year higher after the increase in insvestment costs and in production. There is another increase in the production by A b) 10 % in this variant and after deducting investment costs, there is a difference 3 055 066 CZK/year from th original profit. The B variant involves a complete cancellation of dairy farming in the collective fatm in Ločenice and a transfer of production to Mokrý Lom. This reduces the number of dairy cows while requiring minimal investment. As a consequence, the profit decreases by 1 150 896 CZK/year. The last C variant offers the construction of a new production barn and milking parlour. The profit, when the production is increased by C a) 5 %, decreases by 90 353 CZK after deducting investments costs. When the production is increased by C b) 10 %, the profit increases by 2 230 498 CZK. Each variant is influenced by many factors, such as the depreciation period of individual investments, expected milk production or difficulty of operation. Each business has its specific requirements for individual factors that are decisive for choosing a concrete variant. Each of them has its pros and cons but still, in this concrete example, the most suitable is the C variant which offers on one hand the most challenging investment, but on the other hand the most sustainable option into future years.

The problematics of installation of automatic milking systems in cattle breeding
KAMÍROVÁ, Anna
This thesis focuses on the construction of the first automatic robotic milking parlor GEA DairyProQ in the Czech Republic: in the Agrodružstvo Blížkovice. The new milking parlor is then compared to their previous milking parlor DeLaval. The comparison is very difficult because it is the old technology compared to the latest robots on the market, but nonetheless, the results speak for themselves. The milking speed increased by 32 % (40 pcs/hour), the number of people working as operators decreased by 67 % (-4 individuals/shift). The parameters of milk were almost unchanged, except for the number of somatic cells, which decreased by 50,000 in 1 ml of milk and for the value of the total number of microorganisms, which fell slightly under 20,000 in 1 ml of milk. Consumption requirements increased significantly, namely by 40% of energy consumption and by 64% of water consumption. Overall, unattractive, and physically demanding work has become work requiring higher qualification of employees in IT area and in the area of handling new technology. With a few exceptions (20 cows/shift), the worker does not manipulate with the milking arm at all and only looks after the smoothness of running of the milking parlor. This technology has proven to be an independently operating device that greatly simplifies previously demanding work in milking parlors, assuming that you are willing to invest properly in modern technology.
