The present study was carried out in nurseries located in the urban area of the municipality of Arauca, whose objective was to determine hemoparasites that affect the horses dedicated to collection in this region of the country. Three farms were taken, 1. Farm with a total of 10 animals, 2. Farm with a total of 10 animals, 3. Old fairground with 10 animals total. EDTA venous blood was taken to analyze blood smears by hemacolor staining on an object slide. In the El Recreo manor ranch and ranch the counters were not found any type of hemoparásitos and in the other it was possible to visualize Anaplasma spp that does not present any correlation statistically significant, since of the 30 horses sampled only 3 gave positive in the analysis of lab. It is possible to be said that these horses as they live in constant competitions remain up to date with vaccines and other protocols of prevention to avoid some affectation in them, therefore the population under study did not throw much significant data
