My personal preference for Deworming goats:

Treating wormy kids and wormy goats

Ivomec PLUS and Valbazen are my choices of anthelmintics (dewormers)  - both get liver fluke as well as the nasty stomach worms that cause anemia. Valbazen is not safe for pregnant does or those who "may" be pregnant as it causes birth abnormalities. But Valbazen is a great dewormer for kids because they are more likely to have tapeworms which the Ivomec or Ivomec Plus does not kill. And Valbazen is great for open (not pregnant) does and wethers and bucks.

Valbazen is a liquid suspension given orally at the rate of 1cc/10lbs of goat body weight.

Ivomec and Ivomec Plus are injectable cattle dewormers that goat owners use "off label" or "extra label" -meaning it has not been approved for use in goats but through experience by goat owners is commonly used safely.

Dewormers of Choice

Always Inject Ivomec and Ivomec PLUS SUBQ

Ivomec PLUS used for all gastro Intestinal worms as well as Liver Fluke

Never use Valbazen on Pregnant Does!

Valbazen Oral Suspension is great for kids, bucks and Open Does

I use Ivomec and Ivomec Plus successfully at the rate of 1cc/40lbs goat weight SUbQ injection for my goats. If they are severely wormy- I use 1cc/30lbs and ALWAYS SubQ in this case because of the possible bleed out from using it orally as explained in the BottleJaw Article in this website.
Oral application is quickly becoming the easy route that goat owners take in administering injectable dewormers. for giving it also leave the system quick- whereas injections work at a slower rate and stay in the body longer.

There are 4 stages of larval development and in order to kill all 4 stages (which have an approximate developmental period of 10 days) we deworm 10 days apart for a consecutive 3 times- so you will deworm , then in another 10 days and again in another 10 days - then again one month later and then on an as needed basis.

Never give any injectable dewormer orally for severely wormy goats as it can cause severe bleed out in the gut:
You are always advised by me to inject Ivomec and Ivomec PLUS injectable- it is made for injecting. When it is given orally it passes through the body within hours. It kills large numbers of parasites quickly and when they die they detach from the stomach lining and intestinal walls,leaving thousands of tiny holes that bleed into peritoneal cavity.
This photo:
shows what happens inside the heavily infested goat if the worms are killed off too quickly via oral application of dewormer- oral application kills too quickly and all the worms let go at once, causing internal bleeding and possible death of the goat- on heavy infested goats you should always administer your dewormer via SubQ injection as it goes into the system slower and works for a longer period of time therefore eliminating the possible (let go internal bleed-out) I am not sure where the idea of administering injectable dewormers orally came about (probably around the time everyone was giving the pour on Cydectin orally - another NONO) but folks.. it is Meant to be injected for a reason. Please.. Inject it.
Oral administration leaves the body in a matter of hours. Injecting it stays in the body for days doing the job it is intended to do. Not reprimanding or meaning to be nasty but this is

I always tell people to use this rule of thumb- 1.Deworm the day after kidding always- because the hormones in the doe who just kids sends signals to the parasite larvae sitting dormant in the body to multiply and they do in the hundreds of thousands literally.
This is called Periparturient rise or postparturient rise. It is associated with the changes in the circulating levels of the hormone prolactin which occur in the goat during pregnancy and a decrease in immunoglσbulin secreted at the gut mucosal surface due to the transfer of immunoglobulin in the plasma to the mammary epithelium followed by it's secretion in milk.

  • 1.Deworm the day after kidding always
  • 2.Deworm the day after you bring a new goat home
  • 3.Deworm after you have castrated, disbudded or an injury has occurred
  • 4. Deworm any goat during a stressful situation- illness, moving kids away from moms, putting bucklings into a new pen, etc. Stress allows parasites to multiply in huge numbers in the body.
  • 5. Deworm the entire herd  at the beginning of Spring  and at the beginning of Fall using the 10dayx10dayx10day method and then as needed per goat  between these scheduled treatments.



An aggressive approach to deworming needs to be followed after kidding- I use Ivomec Plus or Valbazen both of which will kill the adult stages of Liver Fluke as well as the other important gastrointestinal worms - Never use Valbazen on a possibly pregnant doe as it can cause birth defects or early abortion
Again, I use the Ivomec Plus at the rate of 1cc/30 lbs goat weight for severely wormy goats and always injected SubQ and for regular maintenance I use it the the rate of 1cc/40lbs goat weight.
Valbazen is an oral suspension that is given at the rate of 1cc/10lbs body weight. (Valbazen also kills tape worms that Ivomec Plus does not kill) So I keep both on hand.

Remember: To get all stages of developing larvae, the goat needs to be treated every 10 days for 3 treatments then again in 30 days- this kills the larvae as they develop to 3rd and 4th stage larvae.
Milk Withdrawal: Residual concentrations for human consumption of Ivermectin were recovered in milk up to 11 days (oral treatment) or 25 days (subq treatment) post treatment. We use no withdrawal for kid consumption.


Both of these dewormers have a  wide safety margin for error - meaning it is hard to overdose (within reason of course) .

 SafeGuard is not nearly as effective a dewormer for goats unless you are just using it on a kid who you suspect has tapeworms- and again, my choice here is Valbazen.

You can read the  NADA sheets for Valbazen and Ivomec Plus in the Rx section- keep in mind the dose given is for cattle and goats metabolism is much faster requiring a higher dose per pound of goat weight.


NOTE: Levamisole /Tramisole have a very narrow margin for error which means it is very easy to overdose with highly serious adverse reactions and can be fatal - so I never use them.
