Current research and/or projects

Development of genomics tools and management practices to promote animal health, metabolic efficiency, productivity and longevity, reduce their ecological footprint and promote value-added animal products.

Research and/or project statements

- Towards a restricted use of antibiotics and ZnO in pig production: Development of new nutrigenomics approaches based on a better understanding of the interactions between bacterial pathogens, mitochondrial function and zinc levels.

- Innovative micronutrient strategies for maximizing piglet’s robustness and performance during the pre- and post-weaning periods.

- Development of an innovative strategy targeting mitochondria for improving health and resistance of newly weaned piglets, decreasing the needs for antibiotics in swine production and improving food safety.
