Vliv technologie ustájení králíků na jatečnou hodnotu
Žáková, Ludmila
The aim of the diploma thesis was to evaluate the influence of rabbit housing technology on slaughter value. Two experimental groups of rabbits were compared. One group of rabbits was reared in outdoor rabbit hutches, and the other group was reared in a free housing regime. During the fattening period of both groups of rabbits, body length, ear length and weight were measured, all at two-week intervals. After slaughter, individual parts of the JUT were weighed, a sample was taken in the form of one pelvic limb and submitted for laboratory analysis within 24 hours after slaughter. After processing the results of the experiment, it was found that rabbits from the free housing method showed a better average daily gain. On the contrary, as regards the proportion of protein in rabbit meat, a higher value was achieved for rabbits in the pen housing system.

Technika chovu zakrslého králíka
Valentová, Soňa
The bachelor work on Breeding technique of dwarf rabbit describes the breeding of the rabbit in all its contexts. The first part is devoted to domestication, history and significance of dwarf rabbit breeding. Furthermore, breeds of dwarf rabbits kept in the Czech Republic are listed and described. In the second part, the thesis deals with breeding, genetics of breeding and selection in breeding, housing, feeding, and requirements for microclimate, nutrition, reproduction, care and nursing, and rabbit ration health issues with a focus on disease prevention. The last part of the bachelor's thesis is devoted to the evaluation of own breeding of dwarf lops. Attention is focused primarily on reproductive indicators and properties, to the differences between dwarf lops with classic hair, dwarf satin, rex, and satin rex lops. The selected existing breeding was described and evaluated was the average and total number of born and reared cubs of dwarf lops from females with different coat structure, the losses of born cubs, the ratio of the sex of offspring pups, the influence of various factors on the number of litters, and length of pregnancy.

Diploma thesis The analysis of key influences on the market production of carcass rabbits dealt with the own experiment in the small breeding of rabbits. The experiment lasted for one calendar year. During the experiment, 34 litters were born and a total of 162 rabbits. The indicators of the impact on meat production were monitored. These aspects include number of cubs in litter, breeds and crossbreeding, average litter increment, average fattening weight at week 20, average carcass weight, and average yield. In the experiment were 75 % of litters slaughtered at week 20 of fattening. Furthermore, the influence of the season on the increment, weight in the 20th week of life and weight of carcass was observed. The best results in terms of average two-week increment reached litter no. 1 where Californian white rabbit and New Zealand white rabbit breeds were crossbred. The average increment of this litter was 375 grams. The average increment in the experiment was 323 grams. This litter also had the highest average weight in the 20th week of life, it was 3460 grams. The average weight of all litters in the 20th week of life was 2858 grams. With a carcass weight of 1900 g and 1800 g, rabbits from litter No.1 (yield 53 % abs and 52 % abs) had the highest carcass weight. The highest yields were achieved in litter no. 10 (pure New Zealand white rabbits) and 62 % abs. The number of cubs in litters varied from three to seven pieces, overall the number of cubs in this experiment was lower. The average in the experiment was 5 pieces per litter. In the experiment, 60 % of female rabbits and 40 % of male were born. In the experiment, no difference was found between the observed parameters in purebred vs. hybrid rabbits. Furthermore, the influence of the seasons on the monitored parameters was not proven; Economic analysis of breeding confirms the authors mentioned in the theoretical part of the thesis that small breeding with 150–200 pieces of bred rabbits per year is intended for hobby breeding. Breeding like this is profitable only in terms of direct costs. In the economic analysis it was found that number of cubs in litter has the largest share of profitability. Other parameters are negligible compared to litter frequency.
