Danyel Bueno Dalto, Ph.D.

Research scientist

By using new biochemical and nutrigenomic approaches, his research program, always focused on the study of micronutrients (vitamins and trace minerals) aims to improve the litter homogeneity at birth and the robustness (health) of piglets in pre and post-weaning, to develop alternative strategies to the prophylactic use of antibiotics in pigs and to reduce the environmental impact of the sector.

Current research and/or projects

- Establishment of a living laboratory for Quebec - Lac St-Pierre region

 

- Bioavailability of Hg from fish using different cooking preparation – pig model for humans

 

- Validation of a minor and rapid surgical catheterization of the saphenous vein with under-skin exit

 

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

 

- Towards a new feeding approach of neonatal and weanling piglet for optimizing nutritional status, immunity and microbiota and minimizing the use of antibiotics

 

- 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
