Identifying Mange Type
Sarcoptic mange (caused by S. scabiei var. caprae) usually starts as lesions on the head and neck and spreads to a generalized skin condition with thickening of the skin. The Merck Veterinary Manual advocates treatment with injections of ivermectin, doramectin or moxidectin at 200 µg/kg (microgram per kilogram) as effective in curing the disease.
Chorioptic mange (caused by C. caprae) is quite common in goats. The feet and legs develop papules and crusts in a similar pattern to infected cattle. Treatment, if necessary, involves using sprays or dips containing organophosphates (diazinon, metrifonate or propetamphos).
Psoroptic mange, caused by Psoroptes cuniculi, usually affects the ears of goats. The treatment advised by the Merck Veterinary Manual is ivermectin and moxidectin (200 µg/kg) given twice with a 7- or 10-day interval, respectively, is effective. Doramectin (300 µg/kg) given once is also effective. Dipping treatments are 0.3 percent coumaphos, .15 to .25 percent phosmet, .03 to 0.1 percent diazinon and 2 percent hot lime-sulfur, which must be repeated after 14 days. Sprays or dips such as propetamphos, phoxim, amitraz, or flumethrin can be used outside of the United States. Lactating dairy goats should be treated only with lime-sulfur solution.
Occasionally the mange can spread to the head, neck and body and cause severe irritation, especially in Angora goats, that can lose a lot of hair. The disease in Angora goats must be reported in Texas to the Texas Department of State Health Services, according to the Merck Veterinary Manual, but the mange is curable.
Demodectic mange (D. caprae) causes nonpruritic papules and nodules in goats similar to infected cattle, especially over the face, neck, shoulders and sides. The nodule contents can be expressed easily as a thick, waxy, gray substance. This exudate contains mites.
According to the Merck Veterinary Manual, localized lesions can be incised, expressed and infused with Lugol's Iodine or a 1:3 rotenone in alcohol solution. For generalized disease, a daily topical application of 180ml 33 percent ronnel to 1l propylene glycol on one third of the goat's body can be effective. Alternately, a 1:3 solution of rotenone in alcohol applied to a quarter of the body daily can be curative.
