Towards a greater understanding of Contagious Ovine Digital Dermatitis


Norman Hayward Fund



Research Period


Area of study



Investigator(s): Dr Jennifer Duncan

The aim of this study was to investigate the epidemiology of Contagious Ovine Digital Dermatitis in order to inform and develop science based treatment and control strategies for the condition. As a particularly severe and increasingly common cause of sheep lameness, this recently emerged disease poses a serious challenge to sheep welfare in the U.K. Project findings were disseminated through a planned programme of knowledge transfer activities to both the farming and veterinary professions. It was anticipated that vital improvements would be made in both the awareness of CODD and its future treatment and control.
