Effect of housing system and age of laying hens on eggshell quality, microbial contamination, and penetration of microorganisms into eggs
Original language description
Hens of the laying hybrid ISA Brown were used in the study with the objective to evaluate eggshell quality, microbial contamination of eggshells, and penetration of microorganisms into the egg content in different housing systems and at different hen ages during storage time. A significant interaction between the housing system and age was observed in egg weight and most of eggshell quality measurements. However, microbial contamination and penetration were affected mostly by the housing system and storage time. The numbers of Escherichia coli and Enterococcus were higher in free range eggs compared to enriched cage eggs, respectively. The counts of Escherichia coli decreased with storage time. A positive correlation between the total number of pores and penetration of Escherichia coli in both housing systems was observed in the albumen. It can be concluded that the housing system and age of laying hens significantly affected eggshell quality. Microbial contamination presumably affects the penetratio
