We live in an area that is pretty deficient in copper amounts in the soil, which means loose minerals aren’t enough when it comes to copper for the goats. They need additional copper in the form of a bolus 3-4 times a year.


how to give a copper bolus to goats


Over the years we’ve tried a number of ways to get the boluses into the goats. We’ve tried mixing them into their herbal de-worming balls. We tried mixing them into bread and marshmallows. We tried cutting off the end of syringe and mixing it with something like probios and shooting it into their mouths. None of these were particularly successful.

The thing is, you have to get those copper rods WAY down their throats to keep the goats from chewing them. This means the goat will fight you and your fingers will have to also be way down their throats. And I don’t know about you, but those back teeth are sharp and speaking from experience, I don’t want my fingers anywhere near them!

Therefore, the easiest way to copper bolus a goat- is just to get it as far down their throat, using something other than your fingers, and force them to take it!

But before we get to that, let’s talk a little about copper deficiency…


Signs that you Need to Copper Bolus Your Goat:

  • Wiry or rough coat
  • Faded, sun-bleached appearance to their coat. This is especially noticeable in black goats
  • Bald tip or “fish-tail” look to their tail
  • High worm load or having a hard time fighting off parasites


Basically, if your goat looks a bit scruffy, seems to need constant worming, maybe showing signs of anemia. You probably need to address copper deficiency.

How to Copper Bolus a Goat (Using a Bolus Gun)

This is a pretty simple process. You will need 2 people- one to hold the goat and one to insert the copper bolus into their mouth. Or you can put your goat on the milk stand.


If you are new to goats, I recommend reading up as much as you can before you purchase. You can find a lot of articles here on The Free Range Life that will teach you about goat care and be sure to check out The Busy Homesteader’s Goat Management Binder– it’s full of to-do lists, checklists, record keeping sheets, and resource pages that will get your new goat herd off to a great start!

Supplies to give your goats a copper bolus:

  • Copper Bolus capsules. You can use Ultra Cruz for Goats or Copasure. Copasure is dosed for cows, so you would have to open up the capsules and measure out the correct amount. We used Copasure for years because it was the only thing available, but the Ultra Cruz makes things simpler.
  • A bolus gun
  • Something sticky- like peanut butter, selenium/Vitamin E gel, or Probios– this will help ensure the capsule doesn’t fall out of the bolus gun to early and it helps the capsule stick in the rumen so that it has time to dissolve and allow the rods to go where they are supposed to go.

To get ready, place a little bit of your peanut butter or gel in the bolus gun and place a capsule down on top of it.

Then all you need to do is pull out the goat you are dosing so that the others don’t get all up in your face trying to steal your peanut butter or other supplies.

If you are not using a milk stand, have one person hold the goat’s head tightly with it tilted upwards and pry open their mouths. Straddling is the best way to do this- unless you are dealing with a goat with horns.

As soon as the goat’s mouth is open, shove the bolus gun as far back as possible. Really, really far. So far you think you will hurt them or choke them.

Then press the capsule in, remove the bolus gun and hold the goat’s mouth shut until you hear them swallow. You want to make sure that they swallow and not chew the capsule so that the rods stay the correct length and release copper over the next few months as expected.

That’s all there is too it! Much easier than coaxing them to eat a copper rod filled treats or getting your fingers bitten while trying to prevent them from chewing said treats.

Release them back into their yard and don’t feed them for a few hours so that the rods have time set before they get their rumen moving. (It’s not the end of the world if you do feed them after, no need to redose!)



Copper Bolus FAQ


What is the dosage for copper for goats?

The dosage for copper is approximately 4 grams per 100 lbs. Though some give copper at the rate of 1 gm per 22 lbs- which would be closer to 4.5 gm per 100 lbs.

I currently use Ultra Cruz copper boluses for goats which are pre-measured capsules of 4 gm per adult and 2 gm for (older) kids.


Is there a bolus gun available specifically for goats?

So far I haven’t been able to find one, but the market is constantly changing.

I use a small calf bolus gun and then use the probios or peanut butter to help it stick, since the bolus capsule is too small for the syringe.


What happens if the goat chews the capsule?

It’s not ideal, but it’s okay if this happens. The copper rods are a specific size so they stick in the stomach for a slow release of copper. if the goat chews the rods, some will be smaller and have a chance of passing straight through the goat.

You don’t need to redo the bolus, they will still get benefits from the bolus, it just may not last as long.
