The thesis deals with the composition of the fed ration of fattening pigs, especially with the incorporation of wet corn grain as an alternative into the feed of pigs and evaluates its importance in terms of nutritional value. It also evaluates the production properties of pigs and the possibility of influencing these parameters by nutrition. Another part of the diploma thesis is dedicated to the particular experiments, which were carried out in the Agricultural Cooperative Hrotovice. Here the corn was applied to the feed doses at different levels; in the composition of the resulting feed mixture A1 in proportions 40, 25 and 10 % and in the composition of the resulting feed mixture A3 in proportions 70, 50 and again 50 %. In the second experiment was also added the wheat-barley grit in the amount of 17 %. Subsequently, the monitored parameters of utility properties were evaluated together with the evaluation of economic indicators. The results suggest that the best values can be achieved by incorporation of corn in the amount of 10 % for the A1 mixture and 50 % for the A3 mixture. For this variation, the average daily gain was 905 g per day, conversion of the feed was 2,89 kg / kg and the fattening time was 95 days. Results did not demonstrate statistical significance, but from an economic point of view, these values showed the best cost-effectiveness, which could result in a savings up to 143.7 CZK per one fattened pig.

Output gap belongs to standard indicators of inflationary pressures used in central banks. The aim of this paper is to find the answer to the question, whether we can consider output gap as a suitable indicator of inflation for the Czech economy. First hypothesis, which we analysed is that we can estimate output gap only with uncertainty. For confirmation or refutation of this hypothesis we used ten models of estimation of output gap. The second hypothesis is that output gap can be used as suitable indicator of inflation. For testing of this hypothesis we chose gap model from Coe, McDetmott (1997) -- with the level of output gap and the change (difference) of output gap. All tests confirmed, that central bank can use inflation as a useful indicator of inflation.

The aim of this diploma thesis was to elaborate the overview of applied strategies in salmonid rearing under the conditions of intensive aquaculture systems and to evaluate their production effect. Two feeding tests run within the NAZV program QJ1210013. The first feeding test was carried out from 15th May to 12th June 2014 in the Department of Fisheries and Hydrobiology, MENDELU. For this feeding test monosex female population of rainbow trout (Oncorhynchus mykiss) was included. Two types of dry food were administered ALLER AQUA -- ALLER SILVER and BioMar -- INICIO 918. The second feeding test was carried out from 11th June to 3rd September in the salmon farm in Pravíkov (BioFish company). To this feeding test, crossbreeds of brook trout (Salvelinus fontinalis) and arctic char (Salvelinus alpinus) were included. Two types of dry food were administered ALLER AQUA -- ALLER GOLD and BioMar -- EFICO ENVIRO 920. The length-weight parameters of individual fish were measured at the beginning and at the end of tests. The amount of administered feeds was recorded. Also basic physico-chemical properties of water were monitored. At the end of these tests the production (FCR, SGR, PER, etc.) and economy parameters were evaluated. The most favourable FCR (0,63) was achieved in the crossbreeds of brook trout and arctic char fed by ALLER GOLD. The most rapid growth of fish (SGR = 3,68) was achieved in the fish of monosex female population of rainbow trout fed by INICIO 918. The greatest yield (3 700 CZK per 1m3 of water) was achieved in crossbreeds of brook trout and arctic char fed by EFICO ENVIRO 920, when fed costs were 1 487 CZK per 1m3.

The diploma thesis Influence of the breed of cattle on reproduction and production indicators presents a comparison of these two indicators in two breeds, the Czech Spotted cattle and Holstein cattle. Comparison of indicators is processed in order to confirm the accuracy of intent of the farm in Jevíčko, which is called. Holštýnizace of herd. In the field of production indicators Holstein cattle show six days prolonged lactation, which positively affects milk production, the annual production of milk is increased by 1827 kg (farm in Jevíčko), in republic this difference is even higher (2,389 kg). The content of milk components, ie. fat and protein, a farm in Jevíčko has values above average across the republic. In the field of of reproductive performance the percentage of successful pregnancy of both Leeds is comparable, about 5% below referring to the boundaries of good pregnancy. Service period is shorter in Czech Pied cattle. Period is long 103,5 days. With respect to milk production two breeds are within normal limits. Insemination index is at the Holstein breed for the whole period of watching 0.04 higher than in the Czech Pied, however, with respect on last year of watching, the evolution turns and Holstein cattle show the value of this index for 2015 at the level of 1.85, while the Czech Spotted cattle in the same period a value of 1.96. Age at first calving of Holsteins is lower about 31 days, interval between births (meantime) at the Holsteins is higher about 18 days than in Czech Pied of cattle. Meanwhile it takes 381.39 days, due to the length of the service period. Especially individual productivity indicators clearly demonstrate the correctness of intent, reproductive performance seems to be comparable in both breeds. Orientation of the farm in Jevíčko on milk production confirms the correctness of the choice of breed.

This thesis deals with the characterization and description of the commodity chain of rape oilseeds. It defines the development of production and production areas in the European Union and worldwide. Part of the work is devoted to the development of the commodity chain of oilseed rape in conditions of Czech republic. It describes and compares the review of the utilization of rape oilseed in our country. It analyzes foreign trade with this commodity and evaluates the long term developments in the process of EU enlargement. The work characterizes the price trends of oilseed rape and its potential impact on the price of petroleum. Using the data obtained, there are evaluated possibilities of rape oilseed in the future. The obtained results show that the Czech Republic is among the most intense growers and producers of rapeseed in the EU 28 and in the world.

U sivena arktického bylo provedeno testování různých krmiv při odchovu plůdku, půlroční násady a ryb o stáří 1+ do tržní hmotnosti. Součástí experimentu u plůdku byl orientační rozbor celkového tuku v krmivech a těle ryb. Pozitivní vliv krmiva na produkční charakteristiky byl prokázán pouze při odkrmu plůdku, kdy bylo u krmiva DAN-EX 1362 dosaženo signifikantně lepších produkčních výsledků oproti krmivu Milkivit (p{<}0,05). U dalších věkových skupin sivena arktického nebyl mezi testovanými krmivy (DAN-EX 2844, DAN-EX 2446) prokázán žádný signifikantní rozdíl vlivu na produkční charakteristiky. Na konci odkrmu tržních jedinců bylo provedeno zhodnocení jatečné výtěžnosti, odpadu, podílu viscerálního tuku a gonadosomatického indexu (GSI) v závislosti na pohlaví, kde bylo u jikernaček dosaženo průkazně lepších výsledků (p{<}0,05). Součástí posouzení stolní hodnoty tohoto druhu ryby byla senzorická analýza filetů. Na základě výsledků senzorického posouzení byly prokázány horší organoleptické vlastnosti mlíčáků v chuti a konzistenci svaloviny (p{<}0,05).
