The present study was carried out to assess the prevalence of mange mite infestation in district Dera Ghazi Khan (D.G. Khan) and to investigate the effect of sheep mange on different blood and biochemical parameters. Total 400 sheep of different age, sex and breeds were examined from 20 flocks selected in 14 union councils (UC) of Taunsa Shareef. Of 400 selected sheep, only 40 sheep suspected for having clinical signs of mange were examined for presence of different mites through skin scraping examination. For comparison of hematological and biochemical parameters of healthy and infected animals, nine healthy and nine infested sheep of Pak Karakul breed were selected from Livestock Experiment Station, Rakh Khairwala. Prevalence of mange in sheep was recorded as 6% and only one species Sarcoptes scabiei van. ovis was found infesting in Tehsil Taunsa Shareef District D.G. Khan. Maximum cases (8.9%, 4/45) were recorded from UC Vehoa and Nari. Higher prevalence of mange mite was observed in younger animals aging less than six month old (6.9%), male sheep (10%) and Desi breed of sheep (7.6n/o). In mite infested animals, total erythrocyte count (TEC), hemoglobin (Hb) and packed cell volume (PCV) was found to be lower, while erythrocyte sedimentation rate (ESR) and total semen proteins (TP) were higher as compared to healthy animals. Additionally, eosinophilia was also observed in infested sheep. Mange mite infestation is an important problem in the study area, which needs proper attention of the concerned quarters.
