I know this has been probably discussed on an older forum extensively but I looked and couldn't quite find an answer to my questions. So here are my questions: How long after worming with Ivermectin Plus (Equimax Horse Paste) is it considered safe to breed the does. I have read that they shouldnt have the 'plus' ingredient in these as it can cause abortions. I am wanting to worm them before we breed them. We plan on breeding them a month later this year. -Hopefully October to breed. We had hoped to eventually worm them only twice a year but are trying to get on top of a heavy worm load problem and would like to worm them before breeding.. We hadnt adequate pens for them in our beginnings and now we do. I have swept and cleaned out all the smaller pens poo out to bare dirt and are closing those areas off for recovery for the new kids in spring.
