I use this product for my pygmy goats (and horses and chickens and more).
Use it any time that antibiotics are used especially in goats as they need to replenish their good bacteria in their rumen. A simple top dressing over the feed works well. This is a definite must have for your livestock medicine cabinet.
I use this on my sheep after worming or antibiotics to help keep the rumen balanced. I also use it on my rabbits when they have tummy upsets. They don't seem to notice a taste, as their water consumption stays consistent. I always keep it on hand for when I may need it.
