Synergy for preventing damaging behaviour in group housed pigs and chickens

Working Group 1: Genetics
WG1 will focus on links between the expression
of damaging behaviour, and genetics.
The objectives of WG1 are to coordinate
research and share knowledge aimed at developing novel methods for phenotyping
and genotyping for damaging behaviour and health traits, and to coordinate,
share and apply research aimed at mapping transgenerational epigenetic
consequences of early life experiences, with a focus on improving social
behaviour and adaptive capacity.
Pigs: The group will coordinate and
share knowledge related to development of genetic methods to select for
increased disease resistance, and reduced aggression and tail biting by
identifying molecular and phenotypic markers. It will also do the same for
research aimed at developing behavioural, physiological and/or molecular tools
to identify tail biters or pigs that are predisposed to be bitten, for use in
new commercial breeding programmes and on-farm prevention programmes.
Laying hens: The group will share and apply research aimed
at mapping transgenerational epigenetic consequences of early life experiences
with a focus on improving social behaviour and adaptive capacity.
WG1 will also coordinate ongoing research aimed
at investigating the potential of novel breeding strategies targeting indirect,
or social, genetic effects to reduce aggression and tail biting in pigs, and
thereby improve group performance. Positive social interactions and exposure to
a complex environment appear to have a stress buffering effect, which is
accompanied by corresponding epigenetic changes in tissue from pigs and
poultry, and in nucleated red blood cells from laying hens. The group will aim
to identify less invasive blood-based epigenetic markers of stress, which have
potential uses in monitoring welfare status and as molecular markers of
