I use it too. I feed each goat about a tablespoon once a day. It does what Stacy said. My goats have never really gotten sick, so I don't know about that. They do have wonderful coats and I just like knowing it keeps their stomachs/digestive systems in tip top shape. They like it, too. I have used it most of the time I have had my goats, and they are thriving. I know the Fastrack can't be the only thing, but being part of my feeding program, I know it helps. They don't go through much hay and I only feed a bit of grain (though being wethers they don't really need any) and they have healthy coats and bright eyes and good hooves. It's supposed to improve overall health and strengthen the immune system... I'd say it is worth a shot for a few months. Even if you decide you don't want to use it, it can't hurt.
