Current research and/or projects

I'm a research scientist specialised in pig behaviour and welfare. In the last years, my research has mainly focused on the impact of housing and management, including human-animal relationship, on maternal behaviour of lactating sows and social and cognitive development of piglets. I've also worked on the developement of methods for the assessement of welfare of sows and piglets. More recently, I started a research program on alternative production systems, such as pasture-based systems.

Research and/or project statements

Analysis of alternative integrated crop/livestock production systems using life cycle assessment

  • Model integrated agro-ecological crop/livestock production systems to determine their environmental efficiency, as well as potential levers for improvement, using a life cycle analysis from farm to fork.
  • Evaluate the efficiency of these alternative production systems and networks by socio-economic analysis at the farm level, but also downstream by considering the processing, transport, storage and distribution of food products.

Potential of outdoor systems as an alternative to pork conventional production:

  • Survey of economic and technical characteristics of alternative swine production systems
  • Gestating sow preferences for fresh and dry forages
  • Value of fresh or dry forage in the feeding of outdoor gestating sows
  • Sow preference based on forage conservation mode
  • Impact of different types of farrowing huts on the behaviour and performance of sows and their piglets at pasture
  • Strategies for managing high temperature at pasture

Impact of early experience with humans on the human-animal relationship in piglets

  • Development of behavioural tests to assess human reactivity of piglets and a conditioning protocol to associate humans with positive or negative stimuli
  • Process of human recognition and generalization in piglets following positive and/or negative conditioning
  • Emotions and cognitive bias in weaned piglets as a result of human experience
