A recent study done in New Zealand and published in the Journal of Veterinary Parasitology shows that oral administration of moxidectin (sold as Cydectin) is much more effective in goats as either injectable or pour-on. Pour-on was 51% effective, injectable was 55% effective, but oral drench was 91% effective.

It's great to finally see a study that answers this question!
