Sustainability of pig production through improved feed efficiency

Last changed: 04 June 2019

What will the future, sustainable pig production look like? This project includes modelling and evaluation of pig production systems. We work with environmental and social life cycle analyses.

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.


The project, called SusPig, is funded by EU (ERA-Net)

Duration of the project: 2017-2020

Project leader: Lotta Rydhmer

Other contributors: Elin Röös (Dept of Energy and Technology) and Emma Ivarsson (Dept of Animal Nutrition and Management), Ruben Hoffmann (Dept of Economics) and Stanley Zira (Dept of Animal Breeding and Genetics) at SLU, and researchers from Spain, UK, France, Norway, US and Australia.

SusPig is part of “Sustainable production systems for meat and milk”. Stanley Zira is PhD student in this project and SLU’s future platform Future Food is one of the funders.
