Zvěřina jako surovina pro výrobu masných výrobků
Greplová, Jana
The topic of the bachelor thesis is Venison as a raw material for production of the meat products. The thesis defines the terms meat, the game and the venison. It describes the classification of the game, the ways of the hunting and its influence on the venison’s quality and hygiene. The thesis compares the biological and physical risks that may be dangerous for the final consumer. There are a diagram of meat production and possible final products from the venison meat. The separate chapter is devoted to the religion influence is dealt with in a separate chapter, this chapter describes the special requirements for the killing animals and their subsequent consumption in other cultures.

Analýza způsobů uplatnění zvěřiny na trhu z pohledu uživatelů honiteb a návrh jejich optimalizace
Kučík, Martin
In my bachelor thesis I analyze the Czech market with venison and propose its optimization from the producers´point of view. In the thesis I evaluated how the hunted venison is handled and how much it is sold for on average. It is interesting that commercial companies prefer to sell game to the buy-out for all cetegories of venison. On the other hand, individuals keep most of their venison for themselves. A major aspect of this study was how many users own refrigeration equipment and how much venison a trained person inspects. Based on the results, I suggest the most efficient way of selling venison by the user of the hunting ground. I recommend that state-owned companies and religious organizations primarily sell venison in work-in-process portions, while other users prefer to sell directly to the end consumer.

Quality characteristics of farmed and wildlife animals meat
LABUDOVÁ, Kateřina
Venison is currently considered a modern food, both because of its nutritional value, but also because of the ecological method of sourcing. In modern venison history, it has largely replaced livestock meat. This trend was also reflected in attempts to breed wild animals on farms. Farm breeding is also enjoying great success in the Czech Republic. Non-domesticated animals on farms are considered farm animals and their meat is referred to as farm animal meat - deer, fallow deer, mouflon etc. Farmed animals thus represent the possibility of year-round production of this meat as opposed to venison that, which is produced (hunted) for a limited period of time time of year. The aim of the work was to determine the differences in sensory properties and chemical composition between the meat (musculus longissimus dorsi) of males from the farmed breedeng of fallow deer (Dama dama), red deer (Cervus elaphus) and mouflon (Ovis musimon) slaughtered by shooting on the farm and meat of the same species originating from the wild of the Czech Republic. The survey used meat from individuals of the same age and condition with approximately the same time of slaughter at the turn of 2022/2023. The meat was tested by the evaluators using a sensory profile method. Fallow deer meat from wild was found to be a significantly higher (p < 0,05) intensity of color and intensity of veni-son flavour compared to fallow deer meat from farm, while red deer meat from farm was characterized by significantly higher (p < 0,05) pleasantness and color intensity and a higher intensity of venison flavour and also a higher juiciness, in contrast to wild red deer meat. The mouflon meat derived from a farm was found to be significantly higher (p < 0,05) intensity of color compared to wild mouflon meat. A higher palatability of meat were noted for red deer and fallow deer meat from farm, while mouflon meat from wild was marginally better assessed. Also found were differences in chemical composition animals from different production systems. Fallow deer meat from a farm contained significantly more (p < 0,05) of the total protein, while a higher intramuscular fat content was analyzed in farmed fallow deer meat. Red deer meat from a farm contained a significantly higher (p < 0,05) intramuscular fat and total protein content, while red deer venison analyzed had a significantly higher (p < 0,05) water content. A significantly higher (p < 0,05) total protein and collagen proteins content was found in wild mouflon meat.

Transfer of radioactive environmental load to the population of the wild boar (Sus scrofa) in selected localities of the south-western part of the Czech Republic
KOUBA, František
The contamination of the food chain of wild boar by post-Chernobyl radioactive fallout is a continuing problem in the forest ecosystems of certain localities in the Czech Republic. This study/PhD thesis is therefore focused on the evaluation of the results of radioactive contamination by radiocaesium (137Cs) of meat of wild boar caught in the localities of Novohradské Mountains and Šumava National Park in the period from December 2012 to December 2019. The aim of the work was to evaluate the occurrence of radioactive load in wild board, identification of possible seasonal trends in measured values of 137Cs, as well as possible differences in selected localities, and to evaluate the presence of 137Cs in raw materials of animal origin, specifically from wild boar, as a possible source of contamination in the human food chain. During the monitored period from December 2012 to December 2019, 137Cs content was measured in 1607 samples of wild boar, of which 654 samples were from the Novohradské Mountains in the South Bohemian Region and 953 samples from the Šumava - South Bohemian and Plzeň Region. The threshold value of 600 Bq/kg of the total amount of caesium was exceeded in 763 samples out of the total number of 1607, which is 47.5%. The maximum value of 137Cs activity was 22,540 Bq/kg, the median value was 522,4 Bq/kg and the average value was 1368,2 Bq/kg. Statistically significant differences were found between localities Novohradské Mountains and Šumava National Park. Samples from Novohradské Mountains exceeded the threshold 600 Bq/kg in 238 out of a total of 654 samples (36,4 %) of caught wild boar. In samples from the Šumava National Park, samples exceeded the threshold in 525 out of a total of 953 samples (51,1 %). When assessing the seasonal effect of the measured values of 137Cs activity in caught wild boar, statistically significant differences were detected in the winter period (November - April), when 137Cs activity reached higher values. The average value in the winter was 1674,23 Bq/kg, the median value was 741,87 Bq/kg while in the summer period (May-October) the average value was 1022,69 Bq/kg and the median value was 376,51 Bq/kg. Differences in measured values are also visible when taking into account the seasonality. In the period from December to May (each monitored year) there was a noticeable increase in measured values in the localities of Novohradské Mountains, in contrast, in the locality of the Šumava National Park this seasonality is not reflected. In general, higher measured values of 137Cs activity were shown by samples from localities of closed forest ecosystems with no or minimal share of pastures and agricultural land.

Trends in the consumption of selected types wild animals in the Czech Republic in years 1995 - 2010
GRANČAY, Josef
This bachelor thesis is focused on the evaluation of game meat consumption trends from 1989 2010 in Czech Republic. Compares not only its consumption, but also the composition and and nutrient content to other most consumed meats, as game does not reach the top positions of consumption. The thesis summarizes the processing conditions of game, its handling and aging. It also deals with distribution regulations, putting emphasis on laboratory testing and wholesomeness of meat. The work presents the figures of various types of game and its development over the last 22 years. Where in the space is given for comparison. Game meat consumption increases slightly, but room for growth remains.
