read somewhere to ivermectinPLUS, the plus is what gets the tough worm, liver-fluke i think is what was posted. haven't had to do that yet. prior to this episode, how long had it been since you last dewormed this particular goat? i am lucky and have 2 goat vets in our town, and have helped us a bunch with our nubian herd. do know several people that tried boer goats got out because there was no natural immunity to our worms. we found giving cydectin and ivermectin was like giving water, had to go back to the old cow wormer levasole. dont know what to do when that stops working. good luck. also get her vitamin shots, iron because she is anemic, and general vitamins as well
