And questionnaire survey was under taken in 50 farmers to know about the disease and its impact in the study area. An overall prevalence of 28.6% was found by modified Beremannes techinqie examinations. The higher prevalence was observed in female (32.3%) than male (23.8%) and higher prevalence (33.7%) observed in less than 2 years old while the lowest (24.4%) observed in those of greater than 2 years old. Although the prevalence of lungworms was relatively higher in females and lower in less than two years old animals than male and greater than 2 year animals no significant difference was observed between all variables i.e., P>0.05 for all variables.
