Preliminary trial evaluates anthelmintic efficacy of albendazole and ivermectin in sheep and goats, indicating resistance issues.
Key Points
This study aims to evaluate the effectiveness of albendazole and ivermectin against gastrointestinal nematodes in sheep and goats in Sarawak.
Conducted a preliminary experimental trial using faecal egg count reduction test (FECRT) over 14 days.
Administered albendazole and ivermectin to different sheep and goat groups.
Prepared coprocultures to identify third stage larvae (L3) of nematodes post-treatment.
Albendazole showed a 76.8% reduction in epg for White dorper sheep (Group D).
Ivermectin treatment resulted in 85.4% reduction in Barbados blackbelly sheep (Group A), 75.8% in White dorper sheep (Group C), and 75.9% in Saanen goats (Group B).
None of the treatment groups achieved the W.A.A.V.P recommended post-treatment FECR for susceptibility.
