Mylène Blais, Ph.D.

Current research and/or projects

The main objectives related to Dr Blais’s research activities are: 1) To elaborate new strategies to replace the use of antibiotics in the swine industry by improving pig’s immunity and gut health through microbiota optimisation; 2) To develop new technologies and approaches to study swine immune system and gut defenses in response to stress and pathogens; 3) To give a better understanding of swine intestinal and immune development.

Research and/or project statements

  • Early interventions supporting the development of a potent immune system for robust and healthy piglets without the need of AMU using alfalfa silage and cranberry-derived proanthocyanidins applied to the sows and piglets in maternity and nursery.

  • Determine the impact of birth weight and gain weight during lactation on piglets’ immune status, gut development and microbiota.

  • Use of bovine colostrum as a feeding strategy to decrease the use of antibiotics at weaning by improving piglets intestinal defenses and immunity

  • Develop in vitro models of porcine intestinal epithelial cell and immune cell cultures and co-cultures to study intestinal and immune response to enteric pathogens, evaluate the potential of various bioactive products to alleviate inflammation and maintain intestinal epithelial integrity.

  • Evaluate the potential of neonatal fecal transplant to improve piglets’ microbiota diversity, gut development and immunity.
