Vyhodnocení reprodukce a masné užitkovosti na vybrané pštrosí farmě
Rýdlová, Markéta
The goal of the thesis is to evaluate reproduction and meat quality on a selected ostrich farm. Reproduction was evaluated by the number of laid eggs, fertilized eggs, hatched chicks, and raised chicks up to 6 months in the years 2020, 2021, and 2022. Meat quality was evaluated by the influence of gender and muscle type on dry matter, protein, fat, ash, meat brightness, proportion of red and yellow spectrum and the strength of muscle fibbers. During the year 2020, a total of 225 eggs were laid with a hatching success rate of 72.44 %. In 2021, the females laid a total of 159 eggs and the hatching success rate was 83.65 %. In 2022, a total of 214 eggs were laid with a hatching success rate of 80.37 %. Gender did not have a significant effect on the quality indicators of meat. Muscle type did not have a significant (p >0,05) effect on dry matter, protein, intramuscular fat, pH, tenderness, or proportion of red and yellow spectra. Muscle brightness, ash content, and muscle fibber strength were significantly (p <0,05) affected by muscle type.

Netradiční druhy masa a jejich využití pro potravinářské účely
Veselá, Romana
This thesis deals with non-traditional meats and their use for food purposes. Specifically, there are 5 species, namely crocodile, ostrich, buffalo, llama and capybara. These meats are suitable as an alternative to commonly consumed meats, but also as a dietary diversification. In some cases, they are healthier, more nutritious, more dietetically appropriate and more appealing in terms of taste. Their disadvantage is their low availability and often high price. In the food industry, they are used in the same way as commercially available meats for the production of canned meat, sausages, semi-finished products, smoked meat products, dried meat and also directly in restaurants for steaks.

OCCURRENCE AND GENOTYPISATION OF CRYPTOSPORIDIES IN OSTRICHES IN FARM BREED
HEJZLAROVÁ, Adéla
Avian cryptosporidiosis is a common parasitic disease caused by unicellular parasites belonging to the genus Cryptosporidium spp. These parasites have been described as a cause of various respiratory and gastrointestinal diseases of humans, farm and wild animals. Total of 204 faecal samples of common ostriches (Struthio camelus) were collected on four ostrich farms in the Czech Republic. Samples were screened for Cryptosporidium presence by microscopy and PCR/sequencing. Overall, 2.5 % (5/204) and 5.9 % (12/204) of animals were positive for Cryptosporidium by microscopy and PCR, respectively. Phylogenetic analysis of small subunit rRNA, actin and gp60 gene sequences showed the presence of Cryptosporidium avian genotype II (n=7) and C. ubiquitum IXa (n=5). Only ostriches infected with Cryptosporidium avian genotype II shed oocysts that were detectable by microscopy. Oocysts were purified from a pooled sample of four birds, characterised morphometrically and used in experimental infections to determine biological characteristics. Oocysts of Cryptosporidium avian genotype II measure 6.13 × 5.15 m, which is indistinguishable from C. baileyi and C. avium. Cryptosporidium avian genotype II was experimentally infectious for geese (Anser anser f. domestica), chickens (Gallus gallus f. domestica) and cockatiels (Nymphicus hollandicus), with a prepatent period of four, seven and eight days post infection, respectively and not infectious for mice (Mus musculus) and rats (Rattus norvegicus). The infection intensity ranged from 1,000 to 16,000 oocysts per gram. None of the naturally or experimentally infected birds developed clinical signs in the present study.

Využití netradičních druhů zvířat v agroturistice
Krejsová, Gabriela
This bachelor's thesis is concerned with unorthodox animal species in agritourism. At the beginning of this thesis there is defined rural tourism and also utilization of unorthodox animal species in this kind of tourism. In the following chapter are described biological characteristics, technologies and techniques of farming in agritouristic facilities, mainly with focus on llamas, ostriches, crocodiles and bison. A part of the thesis is also an analysis of significance of the animal farming production and animal-assisted therapy. The last part is dedicated to characterization of agritouristic facilities which engage in farming of unorthodox animal species - Lamacentrum Hády and Ostrich farm Doubravice nad Svitavou. There is also included economical evaluation of these establishments. Moreover in Lamacentrum Hády was via a questionnaire survey examined the question of adequate promotion of Lamacentrum Hády among the general public in Brno.

Vyhodnocení projevů chování pštrosa dvouprstého na konkrétní farmě
Konečný, Roman
The main goal of this diploma thesis was to evaluate behavioral manifestations based on data obtained during ethological observation of a breeding triad of ostrich on a farm in Hodějice. Monitoring was performed on a breeding triad (one male ostrich and two female ostrich). Observation was carried out throughout three seasons of the year -- spring, summer and autumn -- by the way of direct observation from 8am till 6pm in 5-minute intervals. The following activities were analyzed: food intake, drinking, defecation, movement, standing, sitting, running, comfort behavior, love call/mating, vocal manifestations. Based on the ethological observation it was ascertained that among most frequent daily activities of ostriches bred on the farm in Hodějice belonged food intake, movement and standing. During spring season the biggest amount of observation was recorded at food intake (30,50 +- 3,45 occurrences). The standing and movement in fowl-run in monitored animals was recorded equally (24,83 +- 1,47, respectively 24,83 +- 4,28 of records). During summer season there was a significant (p < 0,05) increase of time devoted to food intake (35,83 +- 2,21 out of the number of observations). In autumn a significant decrease (p < 0,05) of manifestation of this activity down to 28 +- 3,97 out of the number of observations was documented. From the evaluation of influence of season of the year and sex of ostrich on the behavioral manifestations of ostrich, a significant difference (p < 0,05) in food intake between female ostrich in summer (37,50 +- 2,90 of records) and male ostrich in autumn (27,00 +- 5,24 of records) was determined. In case of "movement" activity, it was recorded a highly significant (p < 0,01) difference in terms of sex of ostrich and season of the year. In autumn season a significant (p < 0,01) increase of "standing" activity was documented in comparison with observation in spring (23,50 +- 0,50 of records) and summer (24,50 +- 0,50 of records) season. Although climatic conditions in the Czech Republic are different from the climatic conditions in original habitat of the ostrich, a negative influence of these conditions on natural manifestations of the ostrich was not detected.

Ostrich meat quality and the situation on the Czech market
LIBÍNSKÁ, Dana
This thesis solves a question of ostrich breeding and carcass processing of ostrich meat. Furthermore the quality of ostrich meat and its position on today market. Ostrich is the biggest living bird on earth whose meat is red and very similar to beef composition but properties are more similar to poultry meat. Ostrich meat, compared to other animal meat, contain low percentage of fat, cholesterol and proteins. For most kind of meat with low fat reflected at the expense of subtlety, but ostrich meat is an exception. Despite its dietary character it provides full-value proteins and important vitamins B. The best quality meat comes from ostriches in the age of 9 ? 14 months, who reached weight of 90-120 kg. The meat gain in the age of 14 months ranges about 32 kg and 42 kg in adult ostriches. Substantial part of the marketable meat comes from ostrich legs (74 %). Ostrich meat unlike beef meat is sold in individual muscles. Meat is divided into steaks, filets, biltong and meat for smoked production.

Analysis of the types of breeding ostriches in the CR
KULÍK, Pavel
This work deals with the problem of analysing of types of ostrich farms in the Czech Republic and the inclusion of different types according to the intensity of farming. It introduces a possible candidate of breeding ostriches with the non-traditional livestock, the origin, history, housing conditions and the economic profits. This work evaluates some selected ostrich farms in the Czech Republic. They were further described and classified into different types of farms according to the intensity.
