Unless you have been keeping goats for a while it would be advisable to get an FEC count done (through your vets), and the get them to advise. Goats will need a higher dose of (sheep)wormer, and an oral one is the usual recommendation.
White wormers do now seem to have a lot of resistance problems, so very few people are using them. Avermectins(like Oramec - twice sheep dose, but make sure you know the weight of your goat) or yellow wormers (1.5 times sheep dose) are usually used.
As no wormers are licensed for goats (except for Eprinex pour-on), your vet should be able to prescribe one for you.
