    Intramuscular fat is very important element in meat quality assessment. This mainly affects consumer's perceptions of taste. I deal with genetic factors influencing the storage of intramuscular fat in beef cattle in my bachelor thesis. The aim of the bachelor thesis was to describe intramuscular fat, factors that influencing storage of intramuscular fat in meat, then I describe the main candidate genes that were analyzed in cattle. Another important part is the description of genotyping and detection of polymorphisms of candidate genes and the description of the importance of studying these genes for the subsequent animal selection

    The aim of this thesis was to compare milking data from farm productivity control and milking systems. Data collection using a PDA was used here as part of a performance check when milk from each dairy cow was recorded manually from a currently calibrated measuring system. The data from the milking system was downloaded from the Farmsoft program, which is used on farms to manage the herd. The comparison took place in 90 dairy cows when 3 lactations were evaluated from each. The difference between the data from the milking parlour system and the KU was confirmed on one of the three farms with more than a 5% probability. The average difference between milk yield was 4.2 kg and the maximum deviation reached 54.1 kg. Several possibilities have been identified as reasons for the difference. The first option is an inappropriate identification device in the form of responders on collars, when there is greater damage and the impossibility of loading dairy cows at the milking parlour. Subsequently, it is possible to point to the different techniques of the milking parlours, where the technology from the BouMatic farm appears to be less reliable. Another possible cause is a misconfiguration of the milking technology with the computer system. Further research into the possible causes of poor identification of dairy cows and the acquisition of innovative technologies for animal identification is recommended

    This bachelor paper focuses on non-clausal temporal adverbials in fiction. The theoretical part characterizes their semantic categories, syntactic realization and the most frequent positions in the clause. Furthermore, it deals with the relationship between temporal adjuncts and verbs in term of the category of tense and aspect. In the practical part, there is introduced and described the style of fiction and further, the findings from the theoretical part are applied to analysis of chosen text in the fiction style in order to state the results of research.Tato bakalářská práce se zaměřuje na nevětná příslovečná určení času v umělecké literatuře.

    Spatial Market Integration: A Case Study of the Polish–Czech Milk Market

    No full text
    Analyses of spatial market integration contributes to the knowledge about market efficiency and provides information to policymakers, as the spatial integration of markets contributes to competitiveness and economic development. Although the integration of agri-food markets is widely discussed in the economic literature, research on the dairy sector is relatively limited. This paper fulfils the research gap with an in-depth investigation of spatial milk and dairy product market integration between two neighboring countries—Poland and Czechia—using regional data, and including both production and processing levels. The econometric analysis of time series covering the period 2001–2021 reveals that only long-run milk and skimmed milk powder (SMP) price relationships are between the Czech Republic and Poland. The results of the study confirm that the factors influencing spatial price relationships between the Czech Republic and Poland are: strong trade ties, the common moment of accession to the EU, a close distance between markets, and region specialization

    Is Market Power or Efficiency behind Economic Performance? The Case of the Czech Food Processing Industry

    No full text
    This article attempts to identify the main reason for the profitability of Czech food processing companies. For this purpose, an analysis of the profitability of the food industry was carried out in the framework of the Structure–Conduct–Performance (SCP) paradigm; specifically, the relative market power (RMP) hypothesis versus the efficiency hypothesis was tested. The analysis used data at the micro-economic level of six Nomenclature of Economic Activities (NACE) sub-sectors of the Czech food processing industry in the period 2016–2020. The final dataset consisted of 2639 observations of 623 companies. The data came from the database of Bisnode Albertina and the Czech Statistical Office. Stochastic frontier analysis (SFA) and a regression model were used in the study. Based on the research carried out, performance does not seem to be explained by a greater market power represented by a firm’s market share. Only one sub-sector was proven to have a higher marginal effect of market power on profitability than technical efficiency. Thus, it can be concluded that companies with relatively larger market shares do not have greater market power and thus do not achieve higher profitability
