Automatizovaný systém pro ekologický chov drůbeže
CÍSAŘ, Aleš
This bachelor thesis proposes a specific technical solution of an automated system for organic poultry farming. After the analysis of the problematics, breeding conditions and obtaining the main parameters that must be met, a modular system was designed. The system takes into account the basic requirements in the form of parameters that condition effective breeding. It is mainly the management of safety, microclimate, food and the final production. Although a key feature of the control system is its autonomous mode, it is supplemented by a mobile application that allows monitoring of the current status and manual control of actuators in particular. The proposed system should help breeders to reduce the cost and time of small-scale poultry farming in mobile hen houses.

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.
