The Meat Utilization of Rabbit Breed Czech Solver
PRAVDOVÁ, Lenka
This master's thesis focuses on the utilization of the Czech Solver, a Czech national rabbit breed, which is registered in The National Programme on Conservation of genetic resources of plants, animals and micro-organisms for Food and Agriculture. The Czech Solver was originally invented to be able to confirm or disprove the purebred origin of the tested animal. This feature is useful for breeders so that compensates for low meat performance breed. Fertility monitored breeding is less than the average fertility medium breeds, among that is the Czech Solver sorted, and significantly lower than the fertility of broiler rabbits. Surveyed individuals have achieved monthly weight gain sampler breeds of rabbits, but fattening period to 2.70 kg live weight ranged from an average of 105 days for semi-intensive rearing system in cages to 135 days at a traditional pens housing system farming, which is at least 27 days longer than the period of fattening broiler rabbits. Average growth rates were observed in the amount of 19.7 g in traditional breeding and 20.6 g in semi-intensive farming. Because the rabbits were slaughtered when reaching 2.70 kg live weight, were at abattoir analysis revealed no statistically significant differences between males and females or between traditional and semi-intensive farming. Slaughter analysis confirmed the breed Czech Solver average percentages of the intermediate part, fore and hind parts of the carcass and a higher proportion of kidney fat compared to other breeds of rabbits included in the genetic resources and compared with broiler breeds.

The utilization of the Czech Solver, the rabbit breed, in Czech Republic
PRAVDOVÁ, Lenka
The bachelor thesis focuses on the utilization of the Czech Solver, a Czech national rabbit breed, which is registered in The National Programme on Conservation of genetic resources of plants, animals and micro-organisms for Food and Agriculture. The Czech Solver, differ other rabbit breeds, is not used for meat or pelt production. It was originally invented to be able to confirm or disprove the purebred origin of the tested animal, hence the name solver. In the genetic code of Czech Solver's fur, four out of five alleles are recessive, which enables the animal to determine the purebred pedigree of a different rabbit breed when the two individuals are crossbred. It is described the required exterior of the Czech Solver is described and the breed is compared to other foreign breeds of the same genetic code. The work includes legislature, organization structure, conditions and possibilities of gaining a financial support for pure breeding of this breed, as well as suggests solutions how to increase the Czech Solver population.

Rabbit gut associated lymphoid tissue (GALT)
NEDOROSTOVÁ, Anna
Presented bachelor project deals with rabbit?s lymphatic tissue of intestine which is the biggest lymphatic organ in a rabbit's body. In the first part of the project anatomical system of a rabbit?s intensine and it's general histological structure is described, following part deals with lymphatic tissue of intensine (Peyers patches, isolated lymphoid follicle, sacculus rotundus, cecal patch, appendix) and supplemented by macroscopic and microscopic images. Histological structure of each GALT component is identical, there are lymphatic follicles covered with special epithelium, however individual GALT components of rabbit differ in percentage of appearance of T and B lymphocyte. All GALT structures are responsible for induction of the immune response, saculus roundus and appendix are locations of formation of the primary antibody repertoire. Project created theoretical foundations for another study about lymphatic tissue of rabbit's intestine.

Analysis of commercial properties broiler breeds of rabbits and their hybrid offspring
KUŽÍLKOVÁ, Petra
The main aim of this thesis was to analyse growth abilities of hybrids (?Nb x ?Kal) in comparison with original parental population. Further were evaluated reproductive properties of parental breeds of rabbits New Zealand White and Californian and their combination (?Nb x ?Kal). Enter data were gathered in total from 27 litters. Obtained data were summarized and statistically treated in MS Excel programme and STATISTICA version 9. To assess the development of live weight, the rabbits were weighed at 7-day intervals from birth until the end of fattening, it is to the age of 126 days. For the analysis of reproductive abilities was in single females litters observed the number of all born offspring, from that the number of live-born and still-born offspring and the number of weaned offspring. Further, the length of gravidity, the length of season and age at weaning, milkiness and total mortality were observed. The assessment of growth and reproductive abilities was made in dependence on sequence of litter and on the observed calendar year. The results showed higher increases in 60th, 90th and 120th days of age hybrid offspring than a breeds pattern book by paternal population requires. The achievement of high weight gains confirms the suitability of using these hybrids for intensive production of quality dietetic rabbit meat. It was also achieved excellent results in milkiness females in the observed breeding. Its average value was 3965 g, which is comparable with milkiness of broiler breeds in large breedings. Total results confirmed the suitability of using Californian rabbit breeds in a maternal position and the New Zealand White in a paternal position to create commercial hybrids intended for fattening. Their hybrid offspring reach better growth ability than original parental population. Results of this study can be specific recommendation especially for small breeders of meat-type rabbits when choosing a suitable combination of breeds for fattening.

Iodine content in meat
TICHÝ, Lukáš
The main goal of my diploma thesis was to review the amount of iodine in meat of foodanimals. This diploma thesis brings current information about the iodine content in meat in The Czech Republic. The samples were extracted during the years 2004 to 2007. On the whole 63 samples, in which the content of iodine was set by Sandell - Kollthof method, were taken. The average content of iodine in meat was as follows : rabbits 19,2; domestic pigs 16,17; market pigs 16,96; wild pigs 57,72 and deer 38,31 g I  kg-1 wet matter. Regional and seasonal differences were proved.
