The ability to accurately estimate the incidence of
ducks affected by health and welfare challenges is of
economic and ethical importance to the poultry industries.
Such estimations enable producers and researchers
to examine the impacts of particular welfare
challenges, such as impaired mobility, on relevant
production outcomes, such as late mortality. When
coupled with historical and current management and
production data, incidence estimates can additionally
provide insight into the underlying causes of a problem
and hence its possible remedies.
