CGIL Seminar: "Effects of prenatal stress in different genetic lines of laying hens"

Date and Time


ANNU 141

Mariana Roedel Peixoto, a Ph.D. Candidate in the Department of Animal Biosciences, will present a CGIL Seminar on Friday, October 11th. The seminar will begin at 1:30 PM in room 141 of the Animal Science & Nutrition building.

Mariana completed her B.Sc. in Animal Science at Sao Paulo State University, Brazil. She first came to Guelph in 2014 for an internship in the Poultry Welfare group under the supervision of Dr. Tina Widowski. In 2015, still with Dr. Widowski, she started an M.Sc. in the Animal Welfare and Behaviour program and transferred to the doctoral program in 2017. For her research, Mariana subjected five genetic lines of laying hens to different prenatal stress models (maternal stress and egg manipulation) and analyzed their effects on the development, behaviour, and stress response of the offspring. She will be presenting the most significant findings of her study.

The Centre for Genetic Improvement of Livestock welcomes all interested University of Guelph staff, faculty, students, as well as industry and academic collaborators to attend our CGIL Seminars, which are held on Friday afternoons throughout the Fall and Winter semesters. The meetings are always available remotely via Fuze, for those unable to attend in person, and presentation recordings may also be available after the seminar. Please let me know if you need further instruction on how to connect to Fuze or view available webinar recordings.  


Have a great week!
