Vomiting Goats and Toxins by: Countryfarm Lifestyles
Vomiting in goats is a good thing as it sounds as if your goat has eaten something poisonous and it is trying to get rid of the toxins.
Usually this happens when goats are allowed into the garden and they eat plants that are toxic for them such as azaleas and rhododendrons.
Feeding your goat some crushed charcoal will help alleviate the situation by binding the toxins. Also try to get your goat to take some olive oil as this will help coat the stomach wall, and some water if your goat looks dehydrated. I would also get hold of your vet.
