Egg quality of three laying hen genotypes kept in conventional cages and on litter.
Original language description
The effects of housing system (conventional cages, litter), genotype (ISA Brown, Hisex Brown and Moravia BSL) and age on egg quality parameters were evaluated. Eggs were sampled three times in the laying period at the age 20 to 24 weeks, 38 to 42 weeks and 56 to 60 weeks. One hundred twenty eggs from each strain, housing system and laying period were collected for egg quality assessment (total 2150 eggs). For egg weight, significant interaction of housing and genotype and genotype and age were determined. Yolk weight was more affected by hen?s age than albumen weight. The effect of housing system on albumen quality was significant with lower values for eggs from the litter system. Significant three-way interactions were found for egg shell surface andalbumen weight.
