The aim of this thesis was to compare the indicators of egg production of hens which are bred for production of consumable eggs i.e. Hy-Line Brown and Hy-Line White in selected farms. Selected parameters of egg production were evaluated during 12-months-laying cycle. In the selected farm during the monitored period was achieved the intensity of laying 86,8 %, laying at the initial state 26.5 eggs, number of eggs included in first quality class 96.4%, mortality of egg layer 1.06%, consumption of compound feed per 1 egg 130.0 g and consumption of compound feed per 1 feeding day 110.8 g. Hy-Line Brown showed higher intensity of laying (88,0 %, respectively 85,2 %), laying at the initial state 26.7 eggs, respectively 26.1 eggs, lower consumption of compound feed 128.7 g, respectively 133.2 g. Hy-Line White showed a statistically significant higher proportion of eggs included in the first quality (97.3%, respectively 85.4%), statistically significant lower mortality (0.49% and 1.51%) and statistically significantly lower consumption mixtures per 1 egg (100.7, respectively 114.9 g).
