The best thing about this guide?

After reading this guide, you will be able to spot the symptoms of barber pole in sheep and also the best available treatments to treat these worms in a definite way.

In short, following the directions directed in the guide will allow the treatment as well the care from this disease in future.

Let’s get started with knowing what a barber pole worm actually is.

What is barber pole worm

Barber pole worms are also known as harmonious contortus. They are potentially harmful blood-sucking roundworm parasites of the true stomach of sheep, llamas, alpacas and goats. 

After entering the body of an animal, they thrive rapidly. If they are left untreated long enough they may cause the death of the animal.

The disease caused by this roundworm in sheep’s stomach is known as haemonchosis that spreads rapidly.

The common symptoms spotted in diseased animals are lethargy, bottle jaw, diarrhoea, poor appetite and anaemia. If anaemia prolongs it leads to death.

The major symptoms spotted in diseased animals are:


Anemia can be spotted by looking at the lower eyelid of sheep. The diseased animal will have white or pale colored eyelid that is normally red or pink.


Bottle jaw is another symptom of barber pole worm attack. In the bottle jaw, the accumulation of liquid can be seen under the sheep’s jaw.

Barber Pole Worm Infestations In sheeps

The infestation of barber pole worms in sheep seems to be different in various age, type and region. The sheeps having tropical origin found to be less infected than others.

Some individual sheep have resistance to this disease over others. As the young sheep or lambs have lower resistance than old ones. So, the young ones are more infected.

Sometimes fluctuations are found in this logic too as the old aged sheep can get infected too but some get immunity or resistance over time.

Barber Pole Worms symptoms In Sheep and Goats

The very first symptom of harbor pole worm (haemonchus contortus) infestation appears is the thin body of sheeps and goats. 

Testing sheep eyes is the way that how to tell if sheep have worms.

Once you note that the sheep is not eating well and not gaining weight, it’s time to spot the symptoms of a disease in sheep. If you spot any symptom, start to diagnose it immediately.

Major symptoms to spot to verify the barber pole worms are:

  • Listless behaviour
  • Weakness of sheeps
  • Diarrhea
  • Edema (bottle jaw)
  • Acute anemia

Instead of waiting to appear these major symptoms if ever you feel the restless behaviour of sheep, start diagnosing after confirming it by FAMACHA eye test.

FAMACHA eye test is the eye test in which the initial color of the inside of the eyelid is analyzed.

Put the testing of eyelids in your habit. Test the colouration of the inner lower eye membrane by schedule time through the FAMACHA test.

If the inner eye membrane seems to be bright pink to white rather than bright red to bright pink then it’s time to start the diagnosis.

How barber pole worm enters into the body of sheeps/goat

The major source of sheep’s infestation by barber pole worms is through eating the worms infested grass.

At first, eggs of barber pole worms are shed in faeces of infected animals. Then these eggs hatch and the larvae from eggs live on the manure.

In the next stage, these larvae move from manure to grass and climb to the upper side. They can climb only 2-3 inches up the grass blade.

Once these worms move to the host (sheep) stomach through eating the infected grass, there they complete their whole cycle of development.

After completing the development phase, they begin blood-sucking through stomach linings and laying for the next generation.


After confirming the real disease and worm to target, now is the time to start diagnosis by a better dewormer. You might need to share/get with a veterinarian to get a proper dewormer if you are new to this field.

A lot of options of dewormers are available in the market to diagnose the barber pole worm.

How to use dewormers for treating barber pole worms?

While deworming an animal like sheep, there is much expertise available. But my personal experience of farming and my veterinarian recommends using the two different wormers of a separate class at the same time.

As choosing one wormer from the fenbendazole i.e safeguard and another one from Lactone class i.e Cydectin. Using the combination of these wormers helps to fight barber pole worms.

The combination of two workers should be given in repeated applications as one day then 12 hours later again, then again used 10 days later.

If it seems any symptoms remain, then apply this combination again after 10 days.

The primary thing to know before using any protocol to treat barber pole worms in sheep is to know the exact weight of sheep.

Using a safeguard wormer helps to protect the animal from repeated infestation again in the near future.

As it seems like that most of these wormers are not labelled for sheep but I added them in the guide because they work for me. Consult a veterinarian if you are confused.

The best way to deworm the animals is to do liquid deworming orally, that is the easiest way. 

The main thing to remember here is to give several doses of pro bios just after deworming. The purpose of probiotics is to give a good start to stomach bacteria that are affected during deworming.

How to care from barber pole worm in future

The best answer to this question is in this popular phrase “Prevention is better than cure.”

To get rid of all the worms from the flock or herd is impossible. Resistance occurrence is a natural phenomenon and it occurs at various time spans in different animals. 

Even by deworming some of the worms still remain alive so the scheduled worming of animals is recommended.

The best care of animals to prevent or minimize the infestation of animals by these deadly parasites.

The primary task to prevent the infestation is by breaking the worm life cycle that is achieved by giving a pause of three weeks of grazing pasture to animals. 

The other techniques to control this worm is by rotational grazing and this technique is most effective to control the disease.

As the larvae can climb up the grass blades to 4 inches so during grazing the grass if left the lower four inches then it will be useful for prevention of intake of the worms.

Leaving this much residual is much desirable in rotational grazing systems.

What happens to the worms if you do deworm? 

Three type of conditions happen by deworming as:

  • Most of the eggs are shed onto the ground surface but most stay inside the host that can be removed by deworming again.
  • If the ground surface is dry, then the larvae inside the shredded eggs will eventually die.
  • If the weather is warmer or moist then the larvae will survive and if ingested by animals it will increase the worm load.

Final verdict

The best way to control the worms is by preventing the infestation in animals by doing rotational grazing to break the life cycle of worms.

The grazing above then lower 4 inches of grass blade is a protective approach to care the sheep from barber pole worms.

If any how the worms attack and the symptoms are found in the sheep, then choose the best wormer for barber pole worms in sheep to start diagnosis.
