Untersuchung und Bewertung von Haarcortisol als retrospektiver Bioindikator für Belastungen beim Schwein
Contact: Dr. Winfried Otten
This project aims to develop and validate a biological indicator for retrospective evaluation of stress using the analysis of hair cortisol concentrations in pigs. For this purpose, a methodological protocol will be developed for hair sampling and hair cortisol analysis in pigs. Individual variation factors will be determined and basal reference values will be defined. The applicability of the biological indicator as a retrospective measure for the severity and length of previous stress experiences of the animals will be validated under experimental and practical housing conditions. Finally, the suitability of this innovative methodology as a welfare indicator in pig housing will be evaluated.
