What Does Mange in Cattle Look Like?

Mange is caused by a mite infestation in cattle. Four mites cause the majority of cases of mange in cattle. Mange primarily affects the skin, causing sores of varying degrees of severity.

  1. Chorioptic Mange

    • Chorioptic mange, or leg mange, is caused by the mite Chorioptes bovis. Some infested cattle will not show any signs, which include papules (small, round, raised spots on the skin), crusts and ulcers on the lower legs. It can also spread to the udder, tail or genital regions.

    Sarcoptic Mange

    • Sarcoptic mange is a very contagious and itchy disease caused by the mite Sarcoptes scabiei var bovis, and it can spread to humans. Papules develop around the head, neck and shoulders. These will crust over, and the skin will thicken.

    Psoroptic Mange

    • Psoroptic mange is cause by Psoroptes ovis. Intense itching starts on the shoulders and rear. Papules develop followed by crusts and skin hardening and thickening.

    Demodectic Mange

    • Demodectic mange is caused by the mite Demodex bovis. The mite does not cause itching. Papules and nodules (lumps) develop over the neck, withers and back. These lesions can develop into ulcers and abscesses.

    Treatment

    • Early treatment with dips (lime-sulfur) or injectable Ivermectin can kill the mites and prevent secondary complications.
