1Assistant Director,
The efficacy of Praziquantel @ 20mg/kg. b. wt. orally against natural infection of S. nasalis in cattle was studied and was found to be 81.96%, 88.52%, 95.08% and 100% effective on 5th, 7th, 15th and 30th day post treatment respectively. The variation in egg count on 30th day post treatment between treatment and control groups were statistically significant (p<0.05). Clinical observations showed reduction in snoring sound on 5th day post treatment and reduction in the mucopurullant nasal discharge on 15th day post treatment onwards. The granuloma gradually reduced and significant reduction was observed on 30th day post treatment.
