NSW northeast and QLD Granite Belt: When to test and when to drench
The times for routine worm testing and drenching in this region. Not all testing or drenching is routine; other times to do these are recommended by the Drench Decision Guide, according to details you provide about your mob of goats.
NSW northwest and Qld Granite Belt: Drench Decision Guide
This tool recommends whether a mob should be drenched, the length of protection warranted and when to worm test again. It is your day-to-day tool on drenching decisions that should be used in conjunction with the annual program of routine testing and drenching times.
The DDG tool steers you through a series of questions about your goats; choose the answer that applies to your mob (or make up your own scenario).
Question and answer
For those who prefer a problem based approach to learning, answer the following questions.
Each of the questions below links further down the page to the answers.
Questions:
- What is the purpose of a strategic drench?
- Which classes of goats receive a routine (strategic) drench, and when?
- The online Drench Decision Guide (DDG) for NSW northeast and Qld Granite Belt assists you to decide whether a mob of goats should be drenched now and when to test again. Open the DDG and answer the questions it offers based on the scenario (from below) that you are using. Try at least three of the following scenarios.
- Does that are currently in early pregnancy on good pasture and in good condition. The recent results showed 65% barbers pole worms and a WEC of 900 epg
- Does close to kidding but you don’t have any low risk paddocks to move them into.
- These are adult non-pregnant goats but 1% are struggling to keep up with the rest of the herd and have pale mucous membranes
- Kids that will be weaned in the next fortnight but there are no low-risk paddocks to wean them into
- A group of bucks in which about 1% have scours or loose faeces
- A herd of adult goats in good condition but on pasture that is now dry and short and the last WEC showed 800 epg. I have no recent worm culture results.

1. What is the purpose of a strategic drench?
Strategic drench: a drench given at a critical time to goats that are susceptible to worm infection (e.g. weaners and pre-kidding does), and also given at times to reduce worm larval contamination of a pasture that will be grazed by the drenched goats over the following weeks or months.
The goats themselves may have had a low worm egg count at the time of this pre-emptive treatment.

2. Which classes of goats receive a routine (strategic) drench, and when?
In this region there are two situations where goats should be drenched without a prior WormTest, these are:
- Pregnant does just prior to kidding when they enter their kidding paddock. The worm challenge is typically about to rise at this time of year and kidding does, which experience a temporary loss of immunity during lactation, can contribute to a large increase in paddock contamination and a source of ongoing infection for themselves and their kids.
- Kids at weaning. Weaned kids are highly susceptible to worms, especially from the stress of weaning. Summer weaning also coincides with high worm-risk weather conditions. Drenching at weaning will help weaners to achieve the growth rates needed for survival.
In both cases use a drench known to be effective on your property. Preferably use a short-acting treatment, and where possible, use a multi-active combination. After these drenches, move the goats into prepared low worm-risk paddocks.
