Four species of artiodactylids (scimitar-horned oryx [Oryx dama]), roan antelope [Hippotragus equinus], blackbuck [Antilope cervicapra]), and blesbok [Damaliscus pygargus phillipsi]) totaling 13 animals were treated with a one-time 12.5-g dose of copper oxide wire particles (COWPs) in a bolus form. Pretreatment, individual trichostrongyle fecal egg counts (FECs) were performed using the McMaster technique. Individual posttreatment FECs were performed every 7 days for 35 days beginning 7 days after bolus administration, and FEC reduction ratios (FECRRs) expressed as percentage reductions from pretreatment values were calculated every 7 days. Mean FECRRs for the 13 animals were 93% ± 16%, 98% ± 7%, 91% ± 28%, 94% ± 16%, and 90% ± 13% at 7, 14, 21, 28, and 35 days posttreatment, respectively. These data demonstrate that COWPs in a bolus form were an effective method for reducing FEC in exotic artiodactylids. Based on this limited data, COWPs show promise as an anthelmintic alternative for exotic artiodactylids in zoologic collections.
