Are these goats showing signs[1] that suggest a worm infection (or are you returning to this Drench Decision Guide from a previous recommendation)?

1Signs of worms

Scour worms (black scour worm [Trichostrongylus species]; brown stomach worm [Teladorsagia circumcincta]; and others [incl. Nematodirus]): dark scours; weight loss; death.

Barber's pole worm: anaemia (pale inside eyelids and gums); 'bottle jaw' (swelling under the jaw); lethargy, lagging or collapse when mustered; death.

NOTE: Other diseases and poor nutrition can cause similar signs. Consult your veterinarian if WormTests do not indicate worms.

Will these goats soon be mustered for a management event?
Which one of the following grazing/pasture conditions apply?
Which one of the following location and seasonal situations apply?

Your Recommended Action

WormTest now, then return to this Drench Decision Guide to see if the worm egg count indicates the need for drenching[1].

No treatment is required now if kids are developing normally and putting on weight (if not seek veterinary advice). WormTest the kids prior to weaning.

Consider a WormTest now, then return to this Drench Decision Guide to see if the worm egg count indicates the need for drenching[1] when goats are yarded.

WormTest now, then return to this Drench Decision Guide to see if the worm egg count indicates the need for drenching[1].

Where possible, move goats to another paddock.

Drench[1] (without a prior WormTest) prior to the flood arrival. Consider a long-acting product only if goats are likely to be isolated for more than 6 weeks and they are in a summer rainfall area and ground conditions are wet. Then move goats to higher paddocks.

WormTest now, then return to this Drench Decision Guide to see if the worm egg count indicates the need for drenching[1]. Consider further WormTests each 2—3 months under these conditions.

Consider a WormTest when the pasture is haying off and in February. Return to this Drench Decision Guide to see if the worm egg count indicates the need for drenching[1].

WormTest each 4—8 weeks (depending on the amount of rainfall) until the season dries out. Return to this Drench Decision Guide to see if the worm egg count indicates the need for drenching[1].

These goats should not require treatment. Review the Drench Decision Guide again if goats show signs[1] that suggest a worm infection, if goats are to be mustered or if seasonal and grazing conditions change.

This mob has a worm egg count result

Drench with a short-acting drench[1] if the mob's WormTest result is equal to or above the threshold figures in the table below for the class of goats and the type of WormTest result.

1Guidelines for worm control treatments

When using anthelmintic products in goats, obtain a veterinary prescription because:

  • Goats require a different dose rate and withholding period to that on the label.
  • Many drenches are not registered for use in goats (see exceptions below).

Victoria: over the counter sheep drenches can be used if residues are kept below the Maximum Residue Limits (MRL).

South Australia: cattle drenches can be used in goats, but pour-on formulations should be avoided.

When giving all treatments

Follow the product labels. Dose to the heaviest goat in the mob. Calibrate equipment to ensure the right dose is delivered with the right procedures. Do not mix drenches unless the label states they are compatible. Check and comply with withholding periods and export slaughter intervals.

Choosing treatment options on your property

Use these principles together, where possible:

  1. Use drenches tested to be most effective on your property and either multi-active products or more than one active concurrently (up the race with one and then the other); if drench effectiveness is unknown, conduct a DrenchCheck after drenching.
  2. Use short-acting treatments—reserve long-acting products for specific purposes or high worm-risk times.

For more details read the drench resistance section in the WormBoss Worm Control Program.

Long-acting treatments

These are rarely necessary in the Rangelands (pastoral) region. You should seek expert advice before using them; more details can be found in the Rangelands (pastoral) WormBoss Worm Control Program.
