Results of egg production in different housing systems

The aim of this work was to present the production results of laying hens kept in different housing systems - conventional cages with different stocking densities, enriched cages or in houses with a range. The used hybrid was Shaver 579 (564 birds). The main production parameters were monitored: No. of laid eggs, laying percentage, mortality rate, feed intake, egg weight and number of culled eggs. Data were analyzed by ANOVA followed by t-test. Main production parameters in production of table eggs were significantly different depending on the housing system. The best results were realized in cage system with lower housing density, and the worst results in hens housed in floor system on free range.
