I'm going to do a FAMACHA check on my sheep and goats, but thus far I have never wormed them myself. I have had the animals a little over a year (except the kids and lambs) Last year my pygmys had a bad case of scabs all over their bodies, and the vet gave the ivermectin subcutaneously. It worked fine. I haven't done anything with parasite management since them. In anticipation, I got some Ivomec injectable from the vet. But a quick scan of goat related web sites says to give this orally instead of by injection? Is that right? And why? What dosage? I don't know what the FAMACHA test will reveal, but one of my nubian does has small scabs on her neck and back, so the mites may be back. I also have eprinex pour on (it's actually not eprinex, but the Tractor Supply equivalent). Are there cases where this is more effective? Any help is appreciated.
