At the time of this article, there are only 3 families of wormers...
1- Benzamidoles fenbendazole (Panacur, Safeguard) • oxfendazole (Synanthic) • albendazole (Valbazen) also kills flukes
2- Cell Depolarizers Levamisole (Tramisol, Levasole) • Morantel/Pyrantel (Rumatel, Positive Pellet) ( this group does not support the use of positive pellets)
3- Avermectins/Milbemycins Ivermectin (Ivomec) • Dormectrin (Dectomax) • Eprinomectin (Eprinex) • Moxidectin (Cydectin) Longrange
If one in a family of wormers stops working, the others will soon follow. We need to do our part, but how?
Do not worm on schedule, but only when needed based on Fecal, body and coat condition, famacha score and weight. Do not rotate wormers. Keep with the same wormer as long as it works. Fecal before and after to see if your wormer is effective. Do not over use. Sometimes 3 days in a row is needed, like when treating for tape worm, other wise heavy loads need 3 times with 10 days between each dose..
DO NOT KEEP DOSING I have seen in desperation producers worming several times a day in an animal with bottle jaw. More wormer does not work faster, it only dumps a ton of chemicals in an already compromised animal. We must give time for the wormer to work.
Use the wormers properly, Im a firm believer if its injectable, inject it, if its oral, give orally and if its pour on...don't use it!! Pour on do not work effectively for internal parasites. If its pellet, toss it!!
There is research that shows injectable can be more effective given orally, BUT this should never be done in heavy loaded anemic goats. Dose is often larger for goats fast metabolism, please read our medication dose page to know what goats need..
Withhold feed for 12-16 hours before worming and then 12 hours after. This is not practical for many. I would at least try worming first thing in the AM before morning feed.
Be proactive, check famacha every time you have your hands on your animals. As often as you can, and sooner during peek months. Hot humid wet weather is peek weather! Barberpole worms lay 10,000 eggs a day. A healthy goats can go from deep pink famacha to pale lids in less than a day!! You must keep watch! PLEASE read the worm page and take time to watch the video, its long but informative! It is our responsibility to keep learning!
We do have other choices. These are more work, but can be very effective
* herbal parasite formulas *Use fresh garlic and ginger paste * quality essential oils.. * Pasture rotation *Animal rotation ( running horses after goats etc) *Cull goats who are susceptible to worm load * Buy proven worm resistant stock
Let's all do our part. Coccidia treatments are loosing ground as well!! PLEASE use treatments correctly!!!
