The subject of the thesis was the analysis of performance characteristics of the broiler Peking duck hybrid Cherry Valley SM3 in the Smilkov a.s. enterprise in the modernized barn in comparison with the data obtained before the modernization of the barn (original barn). Practical monitoring was carried out in the modernised barn, in which a controlled microclimate was applied. Each round was stocked with a quantity of 3 200 ducks. The weighting was always 1 % of the total stacked turn, i.e. 32 ducks. During the period under review, data were collected from 7 turnovers at weekly intervals starting from stacking, i.e., day 1 of age to day 42 of age of the ducks. From the 3rd week of age onwards, the live weight of ducks was lower in the upgraded barn. It was found that at 42 days of age, the live weight in the original barn was 3 596 g, whereas, in the upgraded barn, the live weight decreased to 3 335 g (difference of 261 g). Thus, the data obtained in the modernised barn also showed a lower average daily gain over the period under study (77.8 g), which started to lag behind the average daily gain from the original barn (82.6 g) during fattening, as was the case for the live weight from 3 weeks of age. The difference in average daily gain over the period considered was 4.6 g. The reduction in live weight and average daily gain was related to a reduction in compound feed consumption. During the period under review, the consumption of compound feed decreased from 165.1 t (original barn) to 152.0 t (modernised barn). With lower compound feed consumption, feed conversion improved slightly, decreasing from 2,30 kg/1 kg gain in the original barn to 2,28 kg/ 1 kg gain in the modernised barn. Mortality increased in the modernised barn from 2.87 % to 3.27 % (a difference of 0.40 %). On the basis of the analysis of the mortality data, it can be concluded that the higher mortality was probably due to insufficient cleaning of the sheds or failure to comply with all the disinfection principles when preparing the shed for the following turn.

The aim of the bachelor thesis was to perform practical monitoring of production indicators of broiler hybrid Cherry Valley SM3 in the Smilkov farm Ltd. The study was carried out in two breeds (Smilkov and Kouty) with different fattening technology for the period of 1 year. The weighing always included 1 % of the total number of ducks of the monitored batch, i.e., 32 ducks. The results were obtained from 14 batches (7 batches from each barn). The highest live weight was achieved in the Smilkov breed, with an average of 3.52 kg/pcs, while the Kouty breed achieved an average weight of 3.45 kg/pcs. The Smilkov breed also achieved a better average daily gain, which was 83.3 g/head/day, the Kouty breed had a lower average daily gain of 81.5 g/head/day. The Kouty stable, which has a controlled microclimate, showed better results in mortality rate and feed consumption. The average mortality rate was 1.64 % and 153.3 t of complete feed mixture were fed during the period under review. The average mortality rate in the Smilkov farm was 2.87 % and 165.1 t complete feed mixture was consumed, a difference of 11.8 t of feed between the farms. The feed conversion ratio (amount of feed needed per 1 kg of gain) in the Kouty farm was 2.2 kg/1 kg of gain, while in the Smilkov farm the conversion was found to be 2.3 kg/1 kg of gain.
