WormBoss Worm Control Program for Goats – NSW Northeast and QLD Granite Belt

Program summary

The WormBoss worm control program has five components that are most effective when used in combination.

A summary of the components is below (see links on the right under ‘NSW northeast and QLD granite belt’ for details).

1. Use grazing management to create low worm-risk paddocks

  • Prepare low worm-risk paddocks for kidding does and weaners by preventing contamination with worm larvae in the 3 to 6 months before they are needed:
    • Spell paddocks
    • Graze with cattle or horses, grow browse, crops, hay or new pastures, or graze with goats or sheep for up to 3 weeks after the protection period (when killing worms) of an effective drench1.
  • Choose the least contaminated kidding paddocks for the most susceptible kidding does (maidens, twin-bearing, or poorer condition).
  • Provide adequate browse where possible.

2. Breed and feed for goats resistant and resilient to worms

  • Use bucks with better than average worm egg count Estimated Breeding Values (WEC EBVs) in KIDPLAN by choosing the more negative values.
  • Maintain good nutrition to enhance the goat’s immunity to worms.

3. WormTest at recommended times

  • Before these routine opportunities to drench:
    • Shearing (fibre goats).
    • Kid marking (all does).
    • Pre-weaning (all does).
  • Weaning to first kidding: WormTest at 4–6 week (summer) or 6–8 week (winter) intervals after a short-acting drench. If using a persistent drench then see Effective use of long-acting drenches.
  • Bucks: WormTest at 4–6 week (summer) or 6–8 week (winter) intervals after a short-acting drench and ensure a WormTest occurs one month before joining.
  • If DrenchTest results are not available conduct a DrenchCheck 14 days after treatment.
  • At other non-routine times as suggested in the Drench Decision Guide.

4. Drench1,2 strategically at recommended times

  • Quarantine drench all introduced goats with an effective short-acting drench that provides (for meat goats) four drench groups including one from the most recently available products or (for dairy goats) the two drench groups registered for use where milk is for human consumption.
  • Breeding does pre-kidding (as they temporarily lose their immunity).
  • Kids at weaning.
  • Drench individual goats showing obvious signs of worm related illness and WormTest the rest.
  • At other times, use the Drench Decision Guide to make drenching decisions.

5. Manage drench resistance

  • Conduct DrenchTests every 2–3 years. Use DrenchChecks between DrenchTests or if there are not enough goats in your herd to conduct a DrenchTest.
  • Avoid unnecessary drenching by restricting treatment to recommended times or in response to WormTest results.
  • Use effective drench groups3 and multi-active combinations where possible. Note: multi-active combination and other drenches are not registered for use in goats. In some states and territories they can only be used with an off-label prescription from your veterinarian.
  • In general, use short-acting treatments with long-acting products reserved for specific purposes or high worm-risk times and with an off-label prescription from your veterinarian.
  • Calibrate your drench guns, dose to the heaviest goat and follow the label or your veterinarian’s instructions.

3Drench groups are the chemical family to which an ‘active’ belongs. An ‘active’ is the chemical in a drench responsible for killing worms. Some drenches contain more than one active and are called ‘multi-active’ or ‘combination’ drenches. See Drench groups and actives.

This is an up-to-date, integrated regional worm control program for goats in the NSW northeast and QLD Granite Belt region. It builds upon earlier programs and accumulated knowledge, including from the former Department of Agriculture WormCheck program and the experience of researchers, consultants and advisers, as well as new information from the Integrated Parasite Management in Sheep project, funded by Australian Wool Innovation and ‘Parasite control in southern prime lamb production systems’, funded by Meat and Livestock Australia.

The program aims to improve the profitability and welfare of your goats through:

  • fewer deaths and illness from worms
  • fewer drenches, particularly long-acting drenches
  • improved productivity
  • prolonged life of drenches

When using anthelmintic products in goats, a veterinary prescription is often required because:

  • Goats require a different dose rate and withholding period than specified on most products, even for many registered goat drenches.
  • Most sheep drenches are useful, but not registered for use in goats.


While cattle drenches can be used at the label rates on goats in South Australia and sheep drenches on goats in Victoria, a veterinary prescription is still required for dose rates recommended for goats.

Each regional WormBoss worm control program has been developed from local research results and experience proven to be relevant and successful for most farms in the region. ParaBoss and the University of New England acknowledge that this is not the only method of worm control in the region and more refined programs can be developed in consultation with your worm management advisor/veterinarian using information and knowledge specific to your property and goats.
