We are two weeks past the last date of cocci treatment. Doeling is eating *nearly* a lb a day of medicated feed. Cocci starting to show up in fecals again. Should we do a preventative treatment at 21 days or a true treatment since she had a heavy burden before? Also seeing quite a few Liver Fluke eggs 10 days post Ivomec Plus...why? We gave her 1.7cc oral for a 50lb doeling. Doesn't that mean that it didn't kill the adults?
