Several quantitative diagnostic techniques are available to estimate gastrointestinal parasite counts in the feces of ruminants. Comparing egg and oocyst magnitudes naturally infected samples has been a recommended approach rank fecal techniques. In this study, we compared Mini-FLOTAC (sensitivity 5 eggs per gram (EPG)/oocysts (OPG)) different averaged replicates modified McMaster 33.33 EPG/OPG) 387 from 10 herds North American bison Central Great Plains region USA. Both were performed with slurries homogenized fill-FLOTAC device. study population, prevalence strongyle eggs, Eimeria spp. oocysts, Moniezia Trichuris was 81.4%, 73.9%, 7.5%, 3.1%, respectively. Counts oocysts obtained 1 3 technical technique single replicate Mini-FLOTAC. Correlation between two increased an increase number used calculate EGP/OPG. The correlation for EPG when triplicates count high; however, low. Additionally, both show overdispersion parasites herds.
