Haematological changes and clinical manifestations in the experimental caprine sarcoptic mange

Haematological changes and clinical manifestations were studied in experimental caprine sarcoptic mange infestations in Black Bengal goats. The experiment was carried out in humid and moderate temperature conditions. The study was carried out up to day 80 post-infection (p.i.) There were itching, alopecia, arrest of hair growth, thickening and wrinkling of the affected skin. However, after day 70 p.i., further spread of the condition was arrested though there was presence of mites in skin scraping test. There was a significant reduction in haemoglobin (Hb) concentration where significant increase was observed in total leucocytic count(TLC) and eosinophilic count.
