The aim of the bachelor thesis was to compare the meat performance in rabbits of the Czech piebald breed kept in different types of housing. One group of rabbits was kept outdoors in the huts with a range and the other in a classic covered hutch. A total of 38 rabbits were monitored, 19 of them outdoors and 19 in the hutch. There was no difference in the length of fattening between the rabbits in the hutch and the outdoor (141.47 or 142.32 days) and in the live weight before slaughter (2.62 kg or 2.61 kg). On the other hand, the difference was very significant in other indicators, e.g. between the weight of the carcass, where the rabbits outside had lower weight (1.70 kg) than rabbits in the huts (1.78 kg). The results were more favourable for rabbits reared in hutch. When monitoring the meat performance indicators by sex, a very significant difference (P 0.001) was found only for the length of fattening. The fattening time for males was shorter (140.05 days) than for females (144.06 days). It was also insignificant for live weight. Other indicators were more favourable for males.

This bachelor thesis is dealing with the weight gains and slaughter yield of chosen meat breeds of rabbits in home breeding. Decisive factor for having a rabbit as a source of high-quality meat, fur and leather is mainly nourishment and feeding. The most suitable method is using of feeding mixture by categories. The main purpose of fattening is profit of rabbits ready for slaughter in the shortest time. Meat with the highest quality is obtaining from young animals that are slaughtered at the age of 3 to 4 months. Breeds that had the fastest progress were combination of Big Siamesen and Blue of Vienna with the fattening of 109 days. Rabbits of combination Californian and Blue of Vienna got to slaughter weight at the age of 123 days and the longest progress of fattening lasts for 137 days for the combination of Big Marten and Blue of Vienna. On the other side, it emerged that the most fertile female was Big Marten Rabbit that gave birth and reared the highest number of young animals. The average slaughter yield of all litters ranged between 52 to 58%. The best slaughter yield value reached rabbits of combination of Big Marten and Blue of Vienna that went up to 57.05%.
Postnatální vývoj sleziny králíka
ŠTĚCHOVÁ, Kristýna
Spleen is the largest secondary lymphatic organ which develops in a short postnatal period. Information on postnatal development of rabbit spleen is minimal in available literary sources. This diploma thesis deals with the weight, morphometric and histological changes of the spleen of rabbits at age 0, 5, 10, 14, 19, 27, 32 and 39 days. During postnatal development of rabbits, a statistically significant (P <0.01) increase in the weight, length and width of the spleen occurred. The spleen of newborn rabbits was a relatively small organ with an average length of 1.03?0.12 cm, a width of 0.2?0.01 cm and a weight of 52.50?9.69 g. At age 39 days the size and shape of spleen of adult individuals (average length 4.97?0.73 cm, width 0.9?0.18 cm and weight 1078.40?143.35 g). Between the weight and morphometric parameters, high correlation coefficients were observed in the range of 0.891 to 0.998. Spleen growth was accompanied by increasing cellularisation of the parenchyma, by strengthening the connective tissue (from 8.04?1.50 m to 31.30?5.51 m) and the progressive occurrence of connective tissue in the parenchyma. In the newborn rabbits, a red pulp with a high level of erythrocytes prevailed in the spleen parenchyma. Lymphatic tissue consisted only of small irregular aggregations of basophilic mononuclear cells around several central arteries. Basophilic and vascularization increased in the course of the age and the white pulp was gradually formed. In 14 day rabbits, the marginal zone was well-known, and primary lymph nodes formed by CD79+ cells were first formed. From 14th to 39th day the spleen gradually increased the frequency and size of the individual compartments, with rare germinal centers observed in the lymph nodes until the 39th day. Throughout the course of the observation, extramedullary haematopoiesis of different intensity was seen in the spleen.

This bachelor thesis deals with the meat production of rabbits in home breeding in large breeds, the Checkered Giant rabbit and Flemish Giant rabbit. For comparison, the middle breed of the California rabbit was used. Small breeders are predominantly medium-sized rabbits for their very good cattle yield and short-term fattening. The most important thing for fattening is to achieve mature maturity in the shortest possible time. In our experiment, the Californian rabbit fattening took 149 days and the average slaughter weight was 3144g. In Checkered Giant rabbit took 171 days and for the Flemish Giant rabbit for 184 days. The average slaughter weight for the Checkered Giant rabbit was 4566g and for the Flemish Giant rabbit 4744g. The lowest slaughter yield of 48.6% in our experiment was achieved by females of Checkered Giant rabbit and the highest 56.7% male California rabbit.
Postnatal changes of selected blood parameters of the rabbit
LAŠTOVKOVÁ, Kristýna
Rabbit is an important laboratory animal used in a big variety of experiments. In these experiments are used rabbits of different age and metabolic activity, which reflects into the haematological and biochemical parameters. There is a lack of information about the haematological and biochemical parameters and their changes in the early postnatal stage of life in the available literary sources. This bachelor thesis focuses on the changes of selected haematological and biochemical parameters during 39 days of the rabbits postnatal stage of life. Acquired data show that since the birth until the 39th day of the rabbits life there had been an increase of the average values of erotrocyns (from 2,81 ? 0,28 to 4,86 ? 0,52 T/l), hematocrit values (from 0,285 ? 0,025 tu 0,34 ? 0,02 l/l) and the volume of hemoglobin (from 99,3 ? 2,0 to 111,6 ? 9,9 g/l) On the other hand, the number of leukocytes had dropped with the age from (from 9,25 ? 3,0 to 5,04 ? 0,66 G/l), as well as the percentages of neutrophilic granulocytes. The highest amount of plasma proteins (78,2 ? 4,27 g/l) was recorded on the fifth day, and a negative dependence was calculated among the plasma proteins and urea(- 0,25). Also the physiological hypercholesterolemia occured. Throughout the evolution od the rabbits were recorded very similar amounts of Ca and Mg in the blood plasma. Alkaline phosphatase and gamma glutamyl transferase had shown hight activity in the curse of the evolution.
Study of molecular organization of cytochrome P450 system
Holý, Petr ; Hodek, Petr (advisor) ; Koblas, Tomáš (referee)
Mixed-function oxygenase systém (MFO systém) plays a vital role in the metabolism of a variety of both endogenous substrates and xenobiotics. This membrane systém consists of cytochrome P450s, NADPH:cytochrome P450 oxidoreductase (POR), cytochrome b5 and NADH:cytochrome b5 oxidoreductase (b5R). Cytochrome P450 catalyzes a monooxygenation of a substrate, while POR and cytochrome b5 represent its redox partners. Cytochrome b5, itself having a redox partner in b5R, effects the reactions catalyzed by the MFO system in various ways, through mechanisms that are not fully understood. This paper focuses on the purification of b5R and POR from rabbit liver. The microsomal fraction obtained by differential centrifugation contained 42 mg of protein per ml. From a portion of the microsomal fraction, b5R was obtained using chromatography on DEAE-Sepharose, CM-Sepharose and 5'-ADP agarose columns. The yield was 0,3 % of ferricynide-reductase activity and the product contained several contaminants in the molecular weight range of 50-70 kDa. A second purification of b5R from the microsomal fraction was carried out using a column of DEAE-Sepharose directly connected to a 5'-ADP agarose column. The b5R product was purified with a yield of 10,9 % and it once again contained several contaminants in the molecular...

The aim of this final work is to give a literal summary of frequent or unusual illnesses, which every breeder can meet in their practise and this work can give general information about etiology, clinical signs, therapy, prevention and prognosis of these illnesses. The work compares the conditions of factory farms and little farms of the aspects of breeding areas, feeding, hygiene and other aspects. In the last part it provides a practical example of the economy of a factory farm and a little farm and the reasoning of vertical processes, which stand behind the economical dates.
Mikrobiologická kvalita masa králíků
Suchomelová, Lenka
The rabbit meat has important nutritional and sensory characteristics, it is dietary and easily digestible. This thesis deals with the microbiological quality of rabbit meat focusing on microorganisms that cause spoilage. The microbiological analysis uses rabbit carcasses from home slaughtering, frozen and vacuum packed from hypermarket and from Brno butchers. There was 20 pieces of rabbit carcasses analyzed. The study monitored main microbiological parameters as total number of microorganisms, the number of lactic acid bacteria, Enterobacteriaceae, psychrotrophic microorganisms and amount of mold and yeast. Concerning conditions of supplying market by rabbit meat, there was the highest number of microorganisms found in the carcasses coming from butchers and the lowest number of microorganisms found in carcasses coming from home slaughtering. Regarding the sampling points, well known fact that the carcasses surface is more contaminated with microorganisms than muscle was confirmed. There were no significant differences between the microbiological contamination of the front part and rear part of rabbit carcasses.
