Reseach Scientist

My research focuses on precision feeding and nutrition and the evaluation of carcass quality. My research team and I aim, with precision feeding, to improve the efficiency by which dietary nutrient are used by developing feeding systems that allow pigs to be fed individually with diets adapted daily to their needs. We can thus produce the same amount of meat with 25% less protein and by reducing by 40% the environmental load of the production and by more than 8% feeding cost. Precision feeding is a key component of the precision farming systems. At the request of the industry, we have also been involved in the assessment of the carcass market value and the verification and updating of the pig carcass classification system.

Current research and/or projects

  • Reduction of nitrogen and phosphorus waste and maximization of gross revenues from feeder pig production using a new numeric method
  • Yield comparisons
  • Phosphore-CRF, Minimizing the phosphorous excretion of growing-finishing pigs by optimizing phosphorus intake from environmental, economical and animal perspectives.
  • Optimization of diets and management of slaughter pig production systems
  • Development of a combined premix formulation method to be used in multiphase feeding systems for growing pigs
  • Estimation of the cutability and lean content of pig carcasses.
  • Development of a method for objective slaughter line evaluation of muscle content in cull cow carcasses to be used in establishing a carcass classification and producer payment system.
