Anthelmintic control failure and associated risk factors reported by farmers in communal sheep farming, Oliver Tambo District, Eastern Cape, South Africa

Year: 2025

Type: article

Abstract: Background: Helminth control on communal farms of South Africa, primarily relies on anthelmintic drugs, administered by farmers without veterinary supervision. This study investigated risk factors associated with farmer-reported anthelmintic control failure on communal sheep farms in Oliver Tambo District of the Eastern Cape of South Africa. Methods: A semi-structured questionnaire capturing farm characteristics, helminth control practices and treatment failure was administered to 107 farmers between January and August 2024. Results: spp. (17%). A total of 15 anthelmintic drug brands were recorded. The most commonly used compounds (46%) were Valbantel, Maxicare and Prodose Orange, all co-formulations of benzimidazoles and salicyanilides. Anthelmintic control failure was reported by 62% of farmers. The predominant sheep crossbreed raised on the farm (Dorper‒Merino), the use of 5- or 10-mL syringes for anthelmintic drug administration, and the absence of sheep weight estimation were statistically associated with farmer-reported anthelmintic control failure. Conclusion: These findings underscore the need for improved helminth management strategies to enhance the effectiveness of anthelmintic treatments in communal farming systems.
