Profil

Min forskning er indenfor basal og anvendt etologi med hovedvægt på udvikling af uønsket adfærd hos fjerkræ, herunder kannibalisme, fjerpilning, sammenklumpning i redekasser, høje niveauer af inaktivitet og de associerede velfærdsmæssige konsekvenser. Jeg undersøger den bagvedliggende motivation og udvikler forebyggende metoder, fx gennem ændringer i de tidlige opdrætsforhold, design af inventar/indhusningsforhold og tildeling af miljøberigelse. Jeg arbejder desuden med velfærdsbedømmelse, både i forbindelse med overvågning og i form af udvikling og validering af metoder til brug under velfærdsbedømmelserne.

Key words: abnormal behaviour, alternative housing systems, behavioural needs, broilers, broiler breeders, environmental enrichment, health, laying hens, mutilation, welfare
