Horse Worming Guide Wairarapa & Wellington

We're starting to see more and more resistance, including the start of Moxidectin resistance - our main tool against life threatening encysted cyathastomes. Please consider changing your worming schedule to one based around faecal egg counts as follows:

Worming guide for the Wairarapa and Wellington areas 

Exceptions:

  • *If you have a very underweight, sick or very high worm count horse that needs a Moxidectin drench, it is safest to do a 5 day course of Panacur 1 – 2 weeks prior to the Moxidectin.
  • When the worming history is unknown for a new arrival, the best quarantine drench is Moxidectin (Equest or Ultramox).
  • Young foals and pregnant mares generally need worming every 6 weeks until 6 months of age, but don’t use Moxidectin (Equest or Ultramox) for this period.
  • Any equine vet will do faecal egg counts for you and make recommendations for timing and type of drench from the results. The typical pattern is that the first year of counts is spent identifying ‘low shedders’ and ‘high shedders’, then in subsequent years the 'low shedders' often can go for even less faecal egg counts and worming, with targeted anthelmintics for the 'high shedders' to reduce the pasture contamination.
