The impact of production processes on emission of CO2 in livestock raising
MAKRLÍKOVÁ, Kateřina
This theses fokus on the enviromental impact of livestock raising cycle (cattle, pigs and poultry). Energetical costs and emissions caused by livestock fattening are counted including processing and transport of the final product ? meat. Conventional and organic farming were compared as well as different forms of housing. SIMA Pro software tool was used for obtaining the emission load. The aim of the work was to find which form of livestock raising has the least environmental impact. This work was created in the European Union internatiponal project M00080-EUS-AT-SUKI Sustainable Kitchen focusing on the emission load of substantial links of vertical production chain.

Blastocystis in pigs
HORSKÁ, Ivana
Blastocystis is an obligately anaerobic protist, commonly found in intestinal tract of numerous animals and humans across whole world. It is genetically very variable and rather enigmatic organism. Many aspects of its biology need to be further studied and clarified. On a chosen farm were during the year 2010 collected samples of pig faeces for parasitological survey. A total number of 40 samples was collected and cultivated by the method of Dobel-Leidlaw (1926). Of them, 19 was positive for Blastocystis. Other samples were checked by molecular methods (PCR). Using them, five Blastocystis sequences were obtained, which clearly belong to subtypes 1 and 5.

Blastocystis in pigs
LAKATOSOVÁ, Lucie
The genus Blastocystis belongs among anaerobic unicellular, polymorphic organisms living in intestinal tract of many invertebrates and vertebrates including humans. Genetic variability and spectrum of hosts of this protist is tremendous. Several subtypes exist that are able to inhabit intestine of specific hosts. For example, the subtype 3 is probably the only human-borne subtype and is therefore most often isolated human subtype. It not clear how many species of Blastocystis exist. Anyway, the best known one is B. hominis isolated from humans. It is possible that Blastocystis is responsible for some diseases. It can be found in both healthy individuals and patients with gastrointestinal disorders. The Blastocystis infection can spread easily via orally transmitted cysts. Blastocystis is commonly found in epidemiological studies. During the year 2009/2010 I collected samples in the breeding and production facilities of a pig farm from different categories (bred or auction sows and boars, female barren, gravid, suckling, and one bred boar). A total of 46 samples was cultivated using two-phase media (Dobell Leidlaw).In most specimens I found Blastocystis and, to a lesser extent, trichomonads.

Price analysis of selected products
KŘEMENOVÁ, Kateřina
The aim of this bachelor work is an analysis of agricultural producer prices of cattle and pigs, developments in industrial producer prices of beef and pork, and consumer prices of beef and pork. The theoretical part describes the pricing and analysis of time series. The practical part of this thesis is an analysis of prices of selected products. Information for processing both parts of the bachelor work were drawn from literature and the internet.

Farms for fattening pigs in terms of noise emitted into the environment.
PAČKA, Jiří
Protecting the environment is one of the most important tasks of the late twentieth and early twenty-first century. Noise is in addition to much more tangible pollution of air and water also one of the environmental hazard. Usage of mechanization at the pig breeding causes noise pollution so the main task of this bachelor thesis was to measure the spread of noise from the near stalls . Measure values and compare them with the prevailing regulatory and health standards and than use formulas to determine minimum, maximum and equivalent sound levels. Then these measured values evaluate and determine whether or not it exceed the maximum noise levels. In the case when standards are exceeded, design measures to reduce noise.

Cryptosporidial infections of pigs
FORNBAUMOVÁ, Iva
Recent genetic and biological characterization studies have identified 2 distinct apparently host-adapted genotypes of Cryptosporidium in pigs, that is, Cryptosporidium suis and the Cryptosporidium pig genotype II. The infection of both the above mentioned Cryptosporidium appears to occur a much less severe disease in pigs than it does Cryptosporidium parvum. Sporadic cases of C. suis in human have been reported, but the risk of infection for human is uncertain.

Cryptosporidial and microsporidial infection on the pig farms, in the Czech Republic
HANZLÍKOVÁ, Dagmar
The cryptosporidia and microsporidia are worldwide spread opportunistic parasites. With regard to their wide host spectra and zoonotic potential there is a significant risk for immunocompromised humans, especially AIDS patients. Natural Cryptosporidium infections in pigs are widespread but generally apathogenic. A total of 411 faecal samples, 39 of sows, 127 of pre-weaned, 122 of post-weaned piglets and 123 of pre-growers from three farms were screened for Cryptosporidium spp. infection using the aniline-carbol-methyl violet staining method and positive molecular characterized (direct sequencing of partial SSU rRNA partial genes and PCR-RFLP at the SSU rRNA). Overall, infections were detected in 84 out of 411 animals (20 %), with highest infection rates among post-weaners (27 %). All positive samples were genotyped based on SSU rRNA sequence analysis. C. suis, Cryptosporidium pig genotype II, and C. muris were detected. The microsporidial infections are very frequent in breeds of pigs. Pigs have been frequently reported to be infected with E. bieneusi. Spores were detected in 258 samples of 342 (75 %). The high prevalence was determined in pre-growers (86 %). Genotyping based on the ITS regions of the rRNA gene identified that most pigs were infected with the species-specific genotype F, while two animals had the zoonotic genotype D and two had genotype Peru 9.
