Sustainability of pig production through improved feed efficiency

Models to assess the sustainability of pig production are further developed and we use these models to evaluate today's conventional animal production systems, and alternative production systems that aim to be more sustainable. Both an existing alternative system in Europe and a future, theoretical system developed in the project will be evaluated. The pigs in the future system have been genetically selected for feed efficiency. The use of feed resources based on biomass that is not wanted by humans as food is important in the project. The first part of the project concerns the evaluation of social sustainability and includes methodological developing in the field of life cycle assessment of animal production systems. Weighting of social and environmental aspects in a comprehensive sustainability assessment is also part of the project.
