Effects of laying hens housing systém on laying performance, egg quality characteristics, and egg microbial contamination

Popis výsledku v původním jazyce

The objective of this study was to compare the performance, egg quality and microbial contamination of egg shells from hens maintained in different housing systems, such as conventional and enriched cages, litter and aviaries. The housing system significantly (P < 0.001) influenced the performance characteristics. The highest egg production, lowest daily feed consumption and feed conversion ratio were measured in conventional cages compared to litter and aviaries. Higher egg shell and albumen qualitieswere observed in conventional cages, whereas hens housed in enriched cages and aviaries laid eggs with a higher yolk index (P < 0.001). The housing system significantly (P < 0.001) influenced the total count of bacteria on the egg surface and the microbial contamination of Enterococcus and Escherichia coli. The lowest values for the total count of bacterial contamination (P < 0.001) were found in eggs from conventional cages (4.05 log colony-forming units (CFU)/egg) and enriched cages (3
