Antiparasitic Resistance Threatens Livestock Productivity, Urges Structured Health Programs
Resistance to antiparasitic treatments, such as dewormers and tick treatments, is becoming a significant issue in livestock farming. During a panel discussion at the AgriHX Expo in Polokwane, veterinarians highlighted the widespread nature of this resistance and the urgent need for farmers to adopt structured herd health programs. Dr. Duncan Green from Green Partnership noted that resistance is often detected when treatments fail to deliver expected results, particularly with ticks. For internal parasites like worms, resistance is harder to identify, requiring tests such as the faecal egg count reduction test. Experts emphasized that resistance is not always due to the product itself but can result from incorrect dosing and administration. They advised farmers to consult veterinarians and follow structured health programs to prevent resistance.
