This is a topic that goes round and round with goat people, and different people use completely different things. We are in an area where worms are pretty common [midwest] and I know we have worms. I have been told totally different things by so many people. Our good friend, who is a LONG TIME goat breeder, and previous judge, etc. He believes in DE, and now we are using it, but I really don't believe in it. I have tried Molly's Herbals and they smell so strong, but I am not sure how that is doing either. So do you believe in DE? I have used Ivermectrin paste for horses in the past, but what is your favorite form of Ivermectrin, if you use it, and where do you get it? Also, what is the average price of having a vet do a fecal test, and do you prefer to do it yourself with your own microscope?
