Christiaan Blignaut, [16 Apr 2025 at 07:42:02]: Good morning, Which dewormer can be added to drinking water to effectively treat Haemonchus in bontebok? Springbok and zebra are also using the same water source. Luis Amaral, [16 Apr 2025 at 08:18:51]: For Haemonchus, I use Virbamax lv 1 ml/10 kg or Maxicare 2 ml /10 kg. Workout the biomass in the camp, calibrate water troughs, and rotate the camps. Virbamax has low toxicity. Also, consider individual treatments of Wirevax with dropout darts to the most affected animals.
