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.
