Abstract
The challenges in establishing HEP in laboratory swine Barone F1, Ventrella D1, Elmi A1, Bacci ML1 1 Department of Veterinary Medical Sciences, Alma Mater Studiorum UNIBO In 1998 from the International Conference on Humane Endpoints (HEP) in animal experiments for biomedical research emerged that HEPs are part of a dynamic process, influenced by scientific developments as well as by animal welfare concerns as they evolve with time.
