Heating of a multifunctional house
Paták, Martin ; Horká, Lucie (referee) ; Počinková, Marcela (advisor)
The aim the bachelor´s thesis is to adrress the heating of a multifunctional building. The thesis consists of three parts: theoretical, computational, an design. In the theoretical part. The work focuses on large-scale heating ond cooling systems using ceiling panels. The computational part involves the design of heating and heat preparation for the multifunctional building, which includes a dental offices, a hair salon, classrooms, offices, and residential unit. An air/water heat pump in split configuration is proposed as the heat source. The building is heated using panel radiators and convectors, Hot water preparation is addressed through a priority non-electric storage tank. An electric heating insert assists in preheating the hot water. Thedesign part includes a technical report and drawings prepared based on the computational part.

ANALYSIS OF MILK PRODUCTION AND FERTILITY OF THE HERD OF CZECH PIED CATTLE
PATÁK, Martin
It is an essential condition of economic production in livestock farming to ensure an adequate level of milk yield and reproduction in dairy cattle herds. Therefore, it is the interest of all dairy farmers in conventional agriculture to have a herd capable of high yield which would be mainly profitable. The aim of this thesis was to evaluate selected indicators of milk yield and fertility rates of the Czech Pied cattle in the agricultural society Dublovice JSC. The observation included 430 cows that finished lactation in the control year 2010/2011. The cows were divided according to the sequence of lactation into groups 1, 2, 3, 4 and other lactations. Furthermore, they were divided according to genotypes (C100, C1, and C2) and their fathers. By the groups sorted by the sequence of lactation there was found a statistically significant difference in milk yield between 1st and 4th, 2nd and 4th, 3rd and 4th and other lactations on the importance level P<0,001. The highest average yield reached the cows with the genotype C100 of 4 and other lactations (8 371 kg). However, the significant effect of genotype on the productivity by the cows according to the sequence of lactation was not confirmed. The highest average yield (8 277 kg) was reached by the daughters of the bull REZ 376 (C59R) and the statistically significant difference on the level of importance P<0,05 was proved. By the service period was significant only the influence of fathers. By the meantime and the first calving age were the differences between groups of no statistic importance. The most common reason for cow elimination was disease of mammary gland (25.9% of the total number of eliminated cows) and postpartum difficulties (20%). By the cows in the observed herd was found a higher milk yield (7 423 kg) in comparison to the average yield of the Czech Pied cattle in the Czech Republic (6 548 kg). Service period, meantime and the first calving correspond to the farming aim of the Czech Pied cattle.
