    Uittreksel

    This chapter compares the performance, welfare, health and hygiene of laying
    hens in different types of non-cage systems, focusing on barn, free range and
    organic systems. These non-cage systems are compared with each other and
    with cage systems. This comparison shows that both between barn, free range
    and organic systems and between non-cage and cage systems large differences
    can be identifi ed. Moving from conventional cages to furnished cages, barn,
    free range and fi nally organic systems results in increasing environmental
    complexity, which is positive for some aspects of hen welfare, but also
    increasing risks for performance, health and hygiene, which is negative for
    other aspects of hen welfare. For the improvement of the welfare of laying
    hens in non-cage systems and furnished cages, we recommend that the focus
    should be on creating a better match between the animals and their husbandry
    environment. Good examples are the development of new housing designs
    that combine the benefi ts of non-cage systems with improved performance,
    health and hygienic status. Further, promising approaches in animal breeding
    and optimizing rearing environments are expected to yield major improvements
    in the welfare of laying hens in non-cage systems and furnished cages.
