Dosing correctly
- Weigh sheep: calculate dose based on the heaviest animal or individual weights
- Calibrate drench gun and ensure products are stored correctly
- Drench correctly: ensure sheep swallow the full amount
- Check the treatment worked: testing ensures you only use anthelmintics which work on your farm
