cannot absorb enough calcium to
sustain a strong bone structure and
their genetically determined high
productivity. In cage-free hens,
strong bones are a prerequisite
as the extra movement and flying
around can be the cause of higher
incidences of fractures, especially
toward the end of their cycle. This
will lead at its slightest form to
reduced feed and water intake, as
hens will have difficulty moving
around to satisfy these needs.
Thus, all measures already taken in
traditional hen nutrition to ensure
enough calcium, phosphorus and
vitamin D are absorbed daily
should be intensified in cage-free
systems.
There is no doubt that many
more issues will be revealed as
the new cage-free systems become
commonplace throughout the world.
We might have resolved one issue,
that of welfare, but we have created
several new ones. It could be false
to claim that nutrition alone can
resolve all these issues, but at least it
can help in alleviating some of them

THERE IS NO
DOUBT that
many more
issues will be
revealed as
the new cagefree systems
become
commonplace.

until a more sustainable resolution
emerges. Until then, it is business as

usual, with the well-known method
of trial and error. ■
