Evaluation effect of Lambdacy halothrin, Zizyphus extract and Cedrus oil in knemidocoptes in poultry

Knemidocoptic mange is occasionally noted in pet chickens. The etiologic agent of this disease is Knemidocoptes gallinae and K.mutans, a sarcoptiform mite. These mites live out their entire life cycle on their hosts. Typically, the crusty and scaly dermatitis associated with this mite is seen at the feet and legs, as may be seen in some pet canaries or budgerigars with the same problem. Facial lesions, however, are particularly uncommonly seen in chickens. A suggestive diagnosis can be established by physical examination findings of a "honeycombed" appearance to the crusts and scales on the feet and legs, or by skin scraping. Treatment is with ivermectin, which may be repeated in 2-week intervals for 2 to 3 total treatments. Not all birds exposed to a bird with this condition necessarily will develop problems, and group treatment is not necessarily always required Cedrus oil a herbal product was trid agains knemidocoptes gallinae and its efficacy was compared with of Zizyphus Extract and Rotenone-orthophenol. In this study 16 broiler with knemidocoptes gallinae infestion treated with cedrus oil and Zizyphus extract .Mite scrapings after topical application of cedrus oil caused complet recovery after 20 days in severe infestation with growth of feather on days 20 post treatment.
