摘要:
A survey of anthelmintic resistance on ten goat farms was carried out. The criterion for resistance was a faecal egg coynt reduction (FECR) of <90 percent based on arithmetic means of 11 to 19 goats per group. It was found that nine of the ten farms harboured nematodes resistant to oxfendazole when used at Smg/kg although on two of these, the FECR's were 89.2 percent and 89.8 percent. Post treatment larval cultures indicatedHaemonchus, OstertagiaandTrichostrongyluswere the resistant genera involved. On none of the ten farms was resistance to oral ivermectin at 0.2mg/kg detected.
