A study on the efficacy of 4 anthelmintics was carried out using a faecal egg count reduction test (FECRT) in 107 goats on a breeding farm at Ol'Magogo, Naivasha, Kenya. The goats were randomly assigned to 7 groups; the first acted as untreated controls and the other groups reveived ivermectin (IVM) @ o.2 mg/kgbodyweight once orally, albendazole (ABZ) @ 5.0 mg/kg, levamisole (LEV) @ 15 mg/kg and rafoxanide (RFX) @ 15 mg/kg orally as 2 doses 24 hr apart. Other groups received albendazole and levamisole (ABZ+LEV) and, levamisole and rafoxanide (LEV+RFX) at the same doses and schedules as and when used individually. Faecal egg counts were measured at treatment (day 0) and 10 and 21 days afterwards. Decreasing efficacies, as measured by 3 different formulate were recorded at day 21 for IVM, ABZ and ABZ+LEV(96%), LEV(54%), RFX(60%) and LEV+RFX(65%). Calculations of 95% confidence limits indicated that resistance was present in the LEV, RFX and LEV+RFX groups. The predominant us e of LEV on the farm for a long period at dose rates recommended for sheep may have contributed to the development of resistance.
