Stefan Gunnarsson

Doctor of veterinary medicine, PhD, Associate professor, EBVS© European Veterinary Specialist in Animal Welfare Science, Ethics and Law.

My general research interest has been health and welfare of poultry, pigs, cattle, and fish. Furthermore, I have worked with evaluation of sustainable farming and food production, incl. organic animal production. Another research area has been the philosophy of health and welfare comparing humans and animals.

My teaching experience includes under-graduate students on basic and advanced level (incl. vet students) incl. PhD course, as well as other target groups for teaching including that I have been invited lecturer to stakeholder’s courses since 1992. At the moment I am main supervisor of one PhD student (externally funded) and I have supervised 4 PhD students and co-supervised 3 PhD students.

I perform research in pigs, poultry and cattle, as well as in sustainable animal production.

I coordinate BroilerNet; a project funded by the Horizon Europe research and innovation programme, running from 2022 until 2026. BroilerNet aims to enhance the resilience and sustainability of the European broiler sector by creating space for interaction between science and practice and co-creation of ready-to-use innovative best practices on broiler farms in Europe. The project has 25 partners in 13 countries.

I was main coordinator of the Core Organic project FreeBirds that generated more insight in the relation between chickens’ free range use and health and welfare of the chickens, as well as, to the consequences for the nutrient load of the soil. T Participating countries are Denmark, Italy, the Netherlands, Poland, Sweden, Turkey, and Belgium, and was coordinated by me 2018-2021.

I coordinate the Swedish parts the following international projects:

- ICT-AGRIFOOD project LivestockSense, in precision livestock farmning in pigs and poultry.

- ERA-net project FareWellDock - Tail docking, tail biting, health and enrichment in pigs.

- Core organic-funded projects HealthyHen and CorePig.

Scientific co-ordinator for Workshop in poultry welfare 2012-2023 (Better Training for Safer Food organised by the EU Commission). Chairperson of the OIE Working group on animal welfare and laying hens production systems 2016-2021. Member of the FVE (Federation of Veterinarian in Europe) Working group on animal welfare since 2019 (chairperson 2023-2024).

In 1992 I became Doctor of Veterinary Medicine, and I took my PhD in 2000, I was Associate professor (Docent) in 2009, and in 2012 Diplomate of the EBVS© European Veterinary Specialist in Animal Welfare Science, Ethics and Law (ECAWBM-AWSEL). I was appointed to the chair of Senior lecturer in Sustainable animal production in 2012.

In my background I have had a wide interest in animal welfare including health, in conventional farming as well as in organic farming. Furthermore, I have a vast experience animal welfare and health in livestock species, i.e. poultry, pigs and cattle, as well as, in game birds and fish. Most of my studies (~270 publications) have been performed in interdisciplinary groups (incl. environmental scientists, philosophers and social scientists) in areas of animal welfare and health in farm animals, nationally and internationally. Through this I have an extended network of scientists nationally and internationally and I have been interacting with stakeholders (incl. authorities in Sweden and DG Sanco). I have a general interest in philosophy and ethics (incl. studies prior to my veterinary degree) which is fundamental in the debate about Animal welfare. I have demonstrated that I am competitive in receiving money, eg. ERA-net, Core organic and Horizon funding. 

In 2004 to 2012 I was head of the department of Animal Environment and Health of the Faculty of Veterinary Medicine and Animal science at the Swedish University of agricultural sciences (SLU) in Skara and Uppsala. Twice I was re-elected, and I resigned after 8.5 years when I was appointed senior lecturer in Senior lecturer in sustainable animal production in large herds, with extension duties.

Since 2022, I am supervising Ivana Rodriguez Ewerlöf an engineer and PhD student within MycoModel - Stop the spread of Mycoplasma Bovis and protect free herds. I have supervied four finished PhD students as main supervisor, and three as co-supervisor. Furthermore, I supervise undergraduate students in their final year projects within the ethology and welfare, veterinary program and MSc in animal science.
