This study was carried out to establish the prevalence and identify the risk factors associated with trematode infestations in Holstein dairy cattle in the Paipa-Boyacá valley. Fecal samples collected from 100 randomly selected cattle were examined using a simple sedimentation technique for differential trematode egg count. Eggs were sought from three groups of trematodes: Fasciola hepatica, Paramphistomum spp., and Cotylophorum spp. The specific prevalence was 12, 9 and 4%, respectively. Substantial overlap was observed in the count of F. hepatica and Paramphistomum spp. The prevalence of the three flukes identified in this study was significantly associated (P < 0.05) with body condition and race, while the prevalence of Fasciola hepatica and Paramphistomum spp., was associated with age. The prevalence of the three main trematodes of importance for animal health with a high rate of mixed infestation together with a poor body condition, suggests a substantial economic loss incurred due to the reduction of livestock productivity in the study area.
