Sarcoptic Mange Infestation in Large White Yorkshire Piglet- a Case Report

A 70 days old Large White Yorkshire weaned piglet of piggery unit of Instructional Livestock Farm Complex, Veterinary College and Research Institute, Orathanadu was presented with the history of severe rubbing of the skin against the sides of the pen, hair loss and weakness. The clinical lesion of alopecia, superficial skin fissures and hyperkeratosis were observed around dorsal region, flank region, both hind legs and ears. Skin scraping was collected and processed by 10% KOH digestion method. Skin scrapings revealed eggs and adult mites of Sarcoptes scabiei. The affected pig was treated with two doses of Ivermectin @200 μg/kg body weight at fortnightly interval. After treatment, pig completely recovered from sarcoptic mange and the parasitological examination of skin scraping not revealed any eggs or mites. Hence, double dose injection of Ivermectin @ 200 μg/kg body weight at fortnightly interval is the best choice of treatment for sarcoptic mange infestation in pigs.
