Ample sunlight and regular grooming are effective tools in minimizing the risk of louse infection. Mange Mange is not a common condition in horses in the United States, but should be considered in a horse which is very itchy and losing hair. There are several types, named for the type of mange mite that causes them. Psoroptic mange mites like to inhabit the mane, forelock, base of the tail, or long feathers on the legs of draft-type breeds. Chorioptic mange mites also have a predilection for the long leg hairs.
Demodectic mange is unusual in horses and is seen mainly in immuno-compromised individuals.
Sarcoptic mange has been altogether eradicated in horses in the United States. Identifying mange in horses requires examination of skin scrapings under a microscope. The use of ivermectin is recommended in treating mange mites, along with topical application of potent chemicals that should be obtained through your veterinarian. Some of these problems are of an infectious nature, while others are more innocuous. Fungi thrive in dark, damp barns, particularly in autumn and winter months.
