Výživa a krmení zakrslých králíků
Halouzková, Soňa
This bachelor thesis on the topic Nutrition and feeding dwarf rabbits I focused on general information about dwarf rabbits as zoological classification, history breeding and use of dwarf rabbits. Much of the work deals with the anatomy, physiology of digestion and absorption of nutrients, which is closely related to nutritional requirements. Further chapters relate directly to nutrition and feeding techniques. I dealt with the general characteristics of nutrients, methods of their determination and the need for individual rabbits categories. Then I said feed mainly suitable for dwarf rabbits and basic principles of feeding. All nutrient standards are established only for domestic rabbits, that's why I said in the last chapter experiment aimed at comparing nutrition claims in domestic and dwarf rabbits. The experimental part involves the preparation of feed mixtures, which I fed my own breeding dwarf rabbits, familiarity with local conditions and tested rabbits and the results of the experiment.

Bachelor thesis deals with rabbit meat. Rabbits are bred worldwide for rabbit meat and rabbit skins. Nowadays prevail farm breeds of rabbits, especially broiler breeds where intensive breeding brojler rabbits lasts 70 to 85 days. When buying slaughter rabbits use the criteria as live weight from 2.5 to 3.6 kg, age 3 to 4 months and meaty part (full fleshy dorsal part). Rabbits are slaughtered at abattoirs rabbit and in some cases at poultry slaughter. Slaughter percentage of rabbit ranges from 50 to 65%, carcass weight is 1.0 to 1.8 kg. In the Czech Republic in 2012 produced 1 211 tons of rabbit meat, of which 90% went for export. Worldwide the year produced 1.8 million tons of rabbit meat. The main producer is China, followed by the European Union. Price of rabbit meat is comparable with meat veal. Rabbit meat is prized for high content of protein, unsaturated fatty acids and low cholesterol.

Growth dynamics in selected rabbit breeds
POUSTKA, Milan
The aim of the thesis was performance comparison of selected populations of three breeds of rabbits, the Moravian Blue (Mm), the Viennese Blue (Vm) and the Dutch rabbit (Ho), that is a large, a medium-sized and a small breed. The monitored aspects were the production characteristics (gain weight and carcass yield) and the reproductive characteristics (the average number of kits born, the number of all kits born, the number of live born and stillborn and successfully weaned kits, the rate of successful pregnancies, the milkness of the doe). The population of each of the breeds was monitored in a selected base of 68 litters of the Mm, 65 litters of the Vm and 84 litters of the Ho. The weight gain of rabbits was monitored in regular intervals from birth until the end of fattening, i. e. until 8 months of age in the Mm and the Vm and until 6 months of age in the Ho. The results were compared with the weight gain required by the breed standard. Based on the observed weight gain, a growth curve has been created using the Richards function in Excel and Statistica 12.0. The monthly weight gain of the monitored breeds was compared. The highest average gain in weight for the Mm was 693 g, for the Ho 480g and for the Vm 539 g. The results show a significantly higher gain in weight throughout the growth period of the Dutch rabbit than is required by the breed standard. The Moravian Blue showed a lower average increase in weight during the first five months of age than is required by the breed standard. High statistical dependence (R = 0,94, p < 0.01) between weight gain and the number of kits per litter was observed during the first month. From the second month dependence get lower. Since the third month of age, this dependence could not be proven. Based on the parameters of the growth curve, the inflection point of growth was established at 59.8 days and weight 1 528 g for the Mm, at 43.2 days and weight 895 g for the Ho and at 67.7 days and weight 1512 g for the Vm. The average number of kits per litter was 6.3 for the Mm, 6.48 for the Ho and 6.23 for the Vm. The milkness was calculated according to the weight of the litter at 2 and 21 days of age. The milkness for the Mm was 3 985 g, for the Ho 2 582 g and 3 176 g for the Ho. A significant statistical dependence (R = 0.97 0.98) between the number of kits in the litter and the milkness was found. The mortality rate was at a low level for all monitored breeds, with the highest (5 per cent) for the Vm , followed by 2.9 per cent forthe Ho and 1.4 per cent forthe Mm. Analysis showed the highest carcass yield for the Dutch rabbit (62.4 per cent), but a lower live weight gain. The carcass yield was 59 per cent for the Vm and only 56.1 per cent for the Mm. Overall, the results of the thesis show a bigger live weight gain in case of the Moravian Blue rabbit provided there are higher demands for housing and feeding. Its progeny shows a greater growth potential and, in some aspects, also better reproductive characteristics. On the other hand, the Dutch rabbit paradoxically reached a higher number of kits per litter and better carcass yield, giving meat of greater quality. The Viennese Blue rabbit had a slightly higher mortality rate than the other breeds but also a relatively large weight gain and carcass yield approaching other medium-sized meat breeds. The results of the thesis can be beneficial for novice breeders in helping them choose the right breed, as well as for existing breeders in helping them improve the strengths and eliminate the weaknesses of these breeds.

Meat yield of rabbits
KREJČÍKOVÁ, Klára
This bachelor thesis deals with a topic of meat yield of crossbred rabbits. The basis assumption of quality of meat production, fur and rabbit skin is a sufficient nutrition as well as genetic disposal. The nutrition and feed depend on breeding and housing technology. Nowadays many types of feed exist. The most important fact in feeding is the time. It is necessary to gain the slaughter weight as soon as possible. In the first experimental group the slaughter weight (2600 g) was gained in 70th day of rabbit's life no matter if it was female or male animal. But in the second one the slaughter weight was gained after 77 days. The increases in weeks of feeding were equal, differences in the first groups were inconclusive, and in the second one there was a difference of 15, 5 g/week (2, 2 g/day) between female and male animals. The consumption of feed was different in those two experimental groups. In the first group there was no evidence of different volume of feed between female and male animals whereas in the second one the female animals consumed more feed than male animals. The difference was 4, 3 g/day. Silybum marianum was added to the feeding mixture in concentration 1, 0 % in the first group and in 0, 2 % in the second one.

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.
