A study was conducted to investigate the efficacy of six anthelmintics in a herd of dairy goats. Pretreat‐ment larval cultures indicated that the goats were infected with Haemonchus conforms and Trichos‐trongylus colubriformis. Three separate treatment regimens were administered. In each trial, mature nonlactating goats were allocated into two treatment groups and a control group. Treatment groups received thiabendazole (TBZ) or levamisole (LEV), mebendazole (MBZ) or fenbendazole (FBZ), and morantel tartrate (MOR) or ivermectin (IVR). LEV, MOR, and IVR reduced fecal strongyle egg counts by 99% to 100% of pretreatment values. The benzimidazole (BZD) drugs changed pretreatment fecal egg counts by +2% to ‐32%. Results of posttreatment larval culture demonstrated the presence of H contortus larvae following the administration of BZD drugs.
