This study describes the prevalence of intestinal helminths in 98 adult working military horses of the Brazilian Sport Horse and Crioulo breeds from the Military Brigade of Rio Grande do Sul, Brazil, before and after treatment with a formulation containing ivermectin and praziquantel. Fecal samples were collected and sent to the laboratory of the Faculty of Veterinary Medicine at the Federal University of Rio Grande do Sul. Parasitological diagnosis was obtained using the eggs per gram of feces (EPG) count method and coproculture for identification of infective larvae. The prevalence of parasitized horses was 40.8% (40/98), with 62.5% (25/40) males and 37.5% (15/40) females. Positive samples showed eggs from the Strongylidae family Baird, 1853 and, in 20%, eggs of Parascaris equorum Goeze, 1782. After anthelmintic treatment and repeated fecal examinations, 13.3% (13/98) of the tests showed Strongylidae eggs, and 86.7% (85/98) were negative. Infective larvae of Gyalocephalus capitatus Looss, 1900, Cylicocyclus radiatus (Looss, 1900) Chaves, 1930, and Trichostrongylus axei Looss, 1905 were recovered from coproculture. The recorded efficacy was 67.5%. Parasitological examinations should be performed periodically to determine parasitic load and select the therapeutic protocol.
