A bit late.... & hopefully you’ve got your answer by now...
But if not - yes. & personally we use endofluke oral cattle concentration - if in doubt on the dose ask your vet, as with many things alpaca it’s at your own risk. We’ve also used closamentin injectable but it’s very thick and it seemed to be a fairly traumatic injection for them. The endofluke has worked much better for both us & them, & ours cheerfully eat it when I mix it into their feed with a healthy dose of garlic granules, that makes administration at lot easier all around!
