Abstract:
Sarcoptic mange caused by Sarcoptes scabiei is one of the most serious problems in commercial rabbit farming. Chronic episodes of Sarcoptic mange causes anorexia, poor growth rate, emaciation and ultimately death of the animal. High housing density in the rabbit sheds and poor hygienic conditions are the most important and critical predisposing factors. The lesions are frequently seen on the ears, nose, feet, and perineal area. Pruritis, seborrhea, alopecia, hypersensitive reaction, crusting, and hyperkeratosis are the clinical indications of Sarcoptic mange. The ear margins are frequently affected by dry crusty lesions. Forty five rabbits of the Rabbit research center, College of Veterinary Science, Rajendranagar, Hyderabad were presented with history of anorexia, pruritis and crusty lesions in ear, face and legs. Skin scraping examination revealed the presence of mites. Treatment was initiated with Ivermectin (Neomec, Intas Pharmceuticals) which was administered subcutaneously at the dose rate of 400 µg/kg bodyweight at weekly intervals for 4 weeks. Supplemental therapy was given daily with Zincovit and Vimeral syrup, 6 drops each orally. All the rabbits recovered by the third week and were free from external lesions. Ivermectin given subcutaneously has been found to be effective in managing mange in rabbits. Supplementation of zinc and vitamins in addition to Ivermectin was found to be helpful in managing drug induced oxidative stress, so that the animals recovered faster.
