Stefan Gunnarsson
Senior lecturer in sustainable animal production in large herds, with special responsibility for extension service

Presentation

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 interest in interacting with stakeholders has always been strong, and I was the chairman of the Animal Welfare Committee of the Swedish Veterinary association (2013-2016), Member in the Animal Welfare council (2013-2016) and the expert group of laying hens of Swedish national board of agriculture (2000-2016).

In 2011 - 2015, I was and expert in animal health and welfare organic poultry and pigs at EPOK at SLU Link. Furthermore, I was the Chairman of the scientific council of the Swedish Organic certification organisation KRAV 2013-2016.

Scientific co-ordinator for Workshop in poultry welfare 2012-2022 (Better Training for Safer Food organised by the EU Commission).

Chairman 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.

Teaching

My teaching experience includes under-graduate students on basic and advanced level 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 3 PhD students and co-supervised 3 PhD students.  I have been the Scientific co-ordinator for Workshop in animal welfare in broiler chickens and laying hens (Better Training for Safer Food organised by the EU Commission, DG Sanco 2012-2016).

Research

I perform research in pigs, laying hens and organic broiler chickens, 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 part of the ICT-AGRIFOOD project LivestockSense, which will be running through 2021-2023.

Previously I have been the coordinator for the Swedish part of the European project FareWellDock - Tail docking, tail biting, health and enrichment in pigs. See How pigs can be reared with intact tails as in Sweden. 

SowNest is led by Rebceka Westin, and in this project we investigate the nest building behaviour in sows. 

FAFSynt - Efficiency and Sustainability of Future Animal Food from Swedish farms and water – The primary production, in collaboration with RISE (coordination Stefan Gunnarsson). The general aim of the project is to identify the state of the art, bottlenecks and future solutions in sustainable farm animal production, with main focus on the primary production, in the context of stakeholder knowledge and opinions. The final aim is to establish a tentative agenda for prioritised areas of future research in a multi stakeholder approach.

I have also been involved in a project about Organic broilers, and in the Horizon 2020 projects Hennovation and 4D4F-Data Driven Dairy Decision For Farmers

Background

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 European College of Animal Welfare and Behavioural Medicine, Sub-Specialty 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 (~250 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 2020 funding. My international work includes being Secretary General in the International Society for Animal Hygiene 2009-2017.

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.

Studies at the University of Lund, Sweden in 1984-1986

a. Basic philosophy 1 year (including Logics, Philosophy of science and Ethics) 1986

b. History of ideas and sciences (Idé- och lärdomshistoria), 0.5 year, 1986

c. History of literature (Litteraturvetenskap), 1.5 year, 1985

Supervision

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.
