We purchased a bred Nubian and the breeder told me to worm her with pour on cydectin two weeks before her due date. Any thoughts? I've read conflicting comments on cydectin. I have been feeding her Noble medicated meat goat grain which contains a coccidiostat. That is what the breeder told me to feed her thru out her entire pregnancy. I did a fecal test this week and she had no parasites.
