Research interests:
Nutrition, feeding and management in pig production with special focus on the relation between nutrition, feeding, management, production, behaviour and health. Protein utilization and alternative protein feed ingredients, organic production systems and roughage supply.
Research goal:
Study and evaluate how factors in the production system, such as feed ingredients, feeding, housing and management affect pigs’ nutrient utilization, production, health and behaviour.
Research skills:
Animal Science, pig nutrition and behaviour. Experimental design, sampling, feed formulation, nutrient requirements, analysis and interpretations of data, scientific writing and project leading. Production and feeding trials in pigs in indoor- and outdoor housing systems, digestibility trials and cannulated pig models.
Previous activities in the scientific society:
- Researcher linked to EPOK, Centre for Organic Food and Farming, for research cooperation, supply knowledge and communication, with special focus on robust systems for organic animal production and animal health.
- Expert in EPI-Agri -European Commission, focus group "New feed for pigs and poultry".
- Contact person in the Swedish EAAP committee (SvEAAP), European Federation for Animal Science.
Director of studies at the department of Animal Nutrition and Management.
Lecturer, course leader and examiner in courses at both basic and advanced level about pig nutrition, feeding and management and organic production systems.
