Abstract
ABSTRACT:The present study was undertaken to record the occurrence of haemonchosis, to study the clinical signs and haemato biochemical changes as well as to determine the therapeutic efficiency of anthelmintic drugs in sheep infected with H. contortus. Out of 823 sheep screened by faecal examination, Strongyle ova were seen in 130 sheep which were subjected to faecal cultures. Haemonchus spp. alone was identified in 118 sheep and Haemonchus spp. along with Trichostrongulus spp. in the remaining 12 sheep. The occurrence of haemonchosis in the present study accounts for 15.79 per cent. The occurrence of haemonchosis was highest in below one year age group, Nellore cross breed and females. The clinical signs commonly observed in sheep affected with haemonchosis in the present study were anorexia, depression to lethargy and pale mucous membranes. The mean EPG recorded in sheep affected with haemonchosis was 1079.17±14.69. Haematology revealed a significant decrease in haemoglobin, packed cell volume, total erythrocyte count and lymphocytes whereas significant increase in total leucocyte count, neutrophils, eosinophils and monocytes were recorded. Serum biochemistry revealed a significant decrease in total protein, albumin and glucose while significant increase in total bilirubin and AST were recorded. Therapeutic trial was conducted by dividing the sheep into three groups with 12 in each group using three different anthelmintics viz., closantel, ivermectin and Allium sativum. Closantel was more efficacious followed by ivermectin and then Allium sativum in the treatment of haemonchosis in sheep. Allium sativum can be used as a safe, cheap, reliable and readily available alternative to highly expensive and unavailable conventional anthelmintics in the treatment of haemonchosis in sheep.
