Developing a welfare assessment system for use in commercial organic
egg production
L. Hegelund, J. T. Sorensen and N. F. Johansen
Abstract
A welfare assessment system is being developed for commercial organic
egg production based on indicators of behaviour, health, system, and
management, which is the general Danish Institute for Agricultural Science
(DIAS) concept for assessing animal welfare at farm level.
The welfare assessment system works as an advisory tool for farmers,
helping them to improve welfare in their flocks. Identification of individual
animals in organic egg production is impossible; therefore, management
and welfare assessment are based on flock evaluation.
Mortality is often a major welfare problem in organic egg production,
to some extent caused by inefficient disease detection and control.
Health indicators are therefore closely monitored, including variations
in liveweight, mortality, food and water consumption, and autopsies.
Severe outbreaks of feather pecking and cannibalism causing excess
mortality are often induced by the presence of stressors. Various stressors,
as well as indicators of stress, are therefore included in the welfare
indicator protocol.
Finally the daily management effort and routines are evaluated on the
basis of a management plan prepared by the farmer and a consultant in
cooperation, as well as by use of interviews.
