vomiting sow

Question
I have an approximately 2 or three year old pot belly pig in with my boar. She was malnourished from the person that I purchased the pig from. She has gained all the necessary weight and is now back to that which she should be. The thing I have noticed now is that after eating a few botes of food she begins to vomit. Most is white frothy and she will do so approximately 4 to 5 times. Could this be that she is pregnant (similar to a human morning sickness), a parasite or something else. If you need more info from me just let me know. This has just started recently and she has no other symptoms, she still is mobile, drinks, etc but when the vomiting occurs she puts herself aside from the boar (to whom she has been with for over a year with no prior problems)

Answer
Could be worms or a  genetic flaw (enlarged epiglottis) or ulcers (try Pepcid).
Try spreading a mush of her pellets on a big plate. This will slow down her eating if she has an enlarged eppiglottis and is choking.

None of our pigs have ever gotten "morning sickness", this is unheard of in pigs, to my knowledge...
I would get a stool sample, have it checked for worms or blood (gastric ulcers).
But am not a vet!
Good luck,
