Look out for signs of psoroptic mange

Published 21 January 11

When observing cattle during housed periods it is important to be aware the different skin disease that may occur. In particular look out for psoroptic mange, as early and accurate diagnosis is essential. 

Unusual skin lesions on cattle, particularly on the rump, shoulders and withers are clinical signs of an infection.  These are not stand alone, and may be seen alongside weight loss, reduced production and intense itching.

Cattle can suffer from this parasite, which is in the same family as the sheep scab mite.  They can carry it in summer with signs only being seen during winter months.  Spread is via contact with other infected animals, therefore care should be taken when purchasing in stock.

Diagnosis is by laboratory tests on skin scrapings taken by the vet, and treatment then prescribed on a whole herd basis.
