Project description:
Preventing feather pecking
and cannibalism is still a major challenge in alternative laying hen husbandry systems
. The occurrence of the two
behavioral abnormalities is multifactorial
and is influenced by many aspects of housing, with conditions during pullet rearing playing an
important role.
In this module, literature results and practical experience
on rearing pullets and laying hens with regard to feather pecking and cannibalism
are discussed. Recommendations for organic pullet rearing,
which contribute to the prevention of feather pecking and cannibalism during rearing and the
laying phase, are derived from this. Some important measures during the
laying phase are also outlined.
Feather pecking and cannibalism can develop very early in
rearing and feather pecking is
most likely related to misguided
foraging behavior. These are two
important basic pieces of information for the pullet breeder.
Specifically, it is recommended for pullet rearing to provide the birds with manipulable material at all times
to enable them to perform their species-specific foraging and foraging behavior
and to give them access to a sand bath, an outdoor climate area and raised perches. Needs-based feeding,
a regular supply of grain in
the litter, the provision of roughage and sufficient eating and drinking space are also important to prevent
feather pecking and cannibalism. Keeping hens at low stocking densities and
in small groups also reduces
the risk of occurrence. The stress on pullets should be kept as
low as possible. In addition to a good house climate, it is important to ensure that the
hens are cared for and that
the management of the
hens is discussed with the laying hen farmer at an early stage in order to minimize stress during the critical rehousing phase.
Attention must also be paid to the effect
of light on the occurrence of feather pecking and
cannibalism, which is, however, very much dependent on the presence of other factors.
The above recommendations are largely taken into account in the guidelines of the
organic farming associations, which have set guidelines for rearing pullets,
. A few additions to these minimum requirements would nevertheless
be useful. Attention must be paid to the
appropriate implementation on the farms in order to prevent the
development of feather pecking and cannibalism.
