This study was performed at field condition in a village of District Dera Ghazi Khan in July 2016. The history of animal reveals decrease production, diarrhea and weight loss with anorexia. Fecal sample was taken directly from rectum of diseased and normal animals and preserved at 4oC until further process. Direct smear and McMaster techniques were performed on the samplesfor identification of worm load in both animals. At day 0, the eggs per gram (EPG) was 200 and 750, respectively in normal and infected animals, while milk production was 9.50kg and 7.75kg and live weight was 580 and 505kg respectively. The anthelmintic efficacy was 93.33% at day 14, while increment of milk production and live weight gain were 0.75kg and 10.00kg in infected animal on 28 days compared with day 0. On statistical analysis, EPG reduction was highly significant (<0.05), increase in milk production, weight gain and body condition score were not significant (>0.05).
