title: Study on skin diseases in sheep from northern Ethiopia.
abstract: A study was conducted to determine the cause and prevalence of skin diseases in local sheep from northern Ethiopia. Of 520 sheep examined 174 (33%) had skin diseases of different causes. The identified causes were lice infestation due to Damalina ovis and Linognatus africanus (21%), sheep pox (8%), sarcoptic mange (Sarcoptic Scab. var. ovis) (4%), dermatophilosis due to Dermatophilus congolensis (3%), and orf (contagious ecthyma) (3%). There was no statistically significant (P > 0.05) association of any of the skin diseases with age and sex of the sheep examined. The occurrence and spread of the diseases were associated with poor management, climatic factors, feed scarcity and inadequate veterinary services. The increasing threat of skin diseases to the development of sheep production warranting an urgent control intervention is indicated.
