University of Bern — Cage-free Layer Hen Genetics

[Farm Animal Welfare] Open Philanthropy recommended a grant of $2,700,000 over five years to the University of Bern to support the work of Michael Toscano’s laboratory. Toscano and his colleagues aim to improve cage-free hen genetics by: Phenotyping four of the most popular layer hen strains in cage-free conditions (they are currently bred only in cages). Identifying genetic markers associated with positive welfare traits (for example, lower rates of keel bone fractures). Working with two large genetics firms to help them integrate these traits into their breeding programs. This falls within our focus area of farm animal welfare.
