I usually give my does Ivermectin Plus at 100 days bred. Last year I gave it to them a little early because I could tell they needed it. This year they have no signs of anemia, no coughing and look the vision of perfect health. Can I depend on these signs to necessitate ‘100 day bred’ worming or should it be viewed as a required precaution? I read that fecals are not always reliable indicators for this worming.
