Applicability of cortisol in hair of pigs as a long-term indicator of stress for on-site evaluation of animal welfare on pig farms

StressChron Framework:

Project code 014
Acronym CORTISOL
Role Coordinator
Research area Contributing to a more sustainable and animal welfare minded food production
Research topic Improving sustainability and animal welfare in aquaculture and husbandry
Vertebrate Mammal
Species Pig (Sus scrofa domesticus)

Abstract:

The research goal is to investigate whether cortisol in hair of pigs (Sus scrofa domesticus) is a valuable biomarker for chronic stress. This forms the foundation for the future development of a biosensor which can be used on farms or in slaughter houses for a quick, easy and cheap way to determine cortisol in the hair of pigs. Hair as a matrix is easy and non-invasive to sample. Hence it is possible to evaluate the stress level and more broader the animal welfare over an extended period of time in an objective, animal-friendly but also logistically and financially feasible way on a large scale.
