Research scientist; vitamins and trace minerals

Dr. Dalto's research aims to advance circular economy by developing more precise and sustainable mineral nutrition strategies to pigs. Additionally, based on the One Health approach, Dr. Dalto develops research focused on improving piglets' health and resistance to diseases through the nutritional use of vitamins and trace minerals and, in collaboration with other AAFC researchers, reducing the development of antimicrobial resistance bacteria and the environment footprint of the swine production chain, increasing resiliency of agro-ecosystems. In collaboration with other AAFC researchers, Dr. Dalto's research helps to mitigate/adapt to climate change by evaluating alternative feed sources for swine.

Current research and/or projects

High levels of selenium to gestation/lactation sows diets to improve sows reproductive performance and neonatal piglets survaivability as well as to promote piglets intestinal development and prevent post-weaning diarrhea

One Health approach to cope with the upcoming restricted use of zinc oxide and copper in swine production.

Transition to agroecological integrated crop-livestock circular systems

High levels of vitamins to gestating sows to improve the transfer of vaccine-specific immunoglobulins against E. coli to piglets

Improving pig resilience and the sustainability of the production chain through mineral nutrition

Impacts of Cu, Zn and other biocides in animal feeds and farm effluents
