Planning your drenching programme:
- The current advice is to have all lambs on a routine 28 day drenching programme using oral triple combination drenches.
- Preparing weaning paddocks by reducing the worm challenge also contributes to improving lamb growth rates. An effective drench removes the adult and larval worms in the lamb, allowing the gut to heal and function normally.
- It is important that every drench you use is as effective as possible. To determine the effectiveness of the drench, collect at least 10 individual faecal samples from lambs one to two weeks after drenching for a faecal egg count. If there are eggs present, this indicates adult worms are still in the lamb.
- Ensure you quarantine drench any new lambs on your property with Zolvix Plus. Zolvix Plus is one of only two effective and registered quarantine drenches in New Zealand as it contains an active that is not present in routine drenches.
- Triple combination oral drenches containing an active from each of the main drench groups (ML, BZ and Levamisole) are your best choice for routine drenches (every 28 days). Having three highly effective drench groups present at the same time significantly slows the development of drench resistance.
