Abstract
The present study was undertaken to know the prevalence, haematobiochemical
changes and to assess anthelmintic resistance in strongylosis of goats. In Retrospective
study, the overall clinical prevalence of strongylosis was 6.64 per cent whereas a point
prevalence of 34.54 per cent was recorded among the gastroenteritis cases during the
period of April 2016 - March 2017. A prevalence of 48 per cent was recorded in farm
study which was 10 per cent in organised farms and 86 per cent in unorganised farms.
Clinical study showed higher prevalence in the goats aged between 1-3 years (51.32%) with
higher disease frequency in females (85.53%). The prevalence was highest in less than one
year age group (42.71%) with higher disease frequency in females (83.33%) under farm
study. Highest prevalence was observed in the month of June (18.29%). Pale conjunctival
mucous membranes, emaciation, inappatence and diarrhoea with foul smelling faeces
were prominent clinical signs observed. Haemato-biochemical changes revealed anaemia,
increased total leucocyte count with eosinophilia and decreased levels of total proteins,
albumin, A: G ratio, serum glucose and elevated levels of globulin and SGOT on the day
of presentation in all the goats affected with strongylosis. Among Fenbendazole,
Ivermectin and Levamisole used for treatment of strongylosis in goats, Levamisole was
found to be effective in eliminating strongyles in goats with higher faecal egg count
percentage of 96.85 per cent where as, FECR less than 90 per cent with fenbendazole
(85.36%) and ivermectin (88.90%) suggestive of developing resistance in strongylosis of
goats in and around Bidar.
