Chorioptic mange in cattle has long been recognised as a common external parasitosis in livestock. Although mites can infest cattle of all classes and ages, C. bovis appears to be most prevalent in housed dairy cows. In 2005, 1190 German large animal vets were sent questionnaires concerning the seasonal prevalence in several types of husbandry in the states of Germany, location of clinical skin symptoms, procedure of diagnosis, influence on milk or meat production, and treatment especially in dairy farming. 367 responded. More than one third of the veterinarians who responded reported chorioptic mange (tail mange) making it a disease of high importance for farm cattle with a negative effect on milk production and meat productivity.
