Recherche et / ou projets en cours
Je suis nutritionniste des ruminants et mon programme de recherche est axé sur le développement de connaissances et de technologies en nutrition pour l’industrie des productions animales. Le but est d’accroître l’efficacité de la production tout en réduisant au minimum les répercussions sur l’environnement.
Domaines de recherche actuels :
- Gestion de l’alimentation et de la nutrition des bovins de boucherie
- Production et nutrition des cultures fourragères
- Atténuation des émissions de méthane entérique attribuables aux ruminants
- Évaluation des répercussions environnementales des systèmes de production de bœuf
- Analyse du cycle de vie à la ferme des émissions de gaz à effet de serre attribuables à l’élevage de bovins de boucherie
- Application de modèles mathématiques à l’élevage du bétail
