Overweight pot bellied pig

Question
We just aided our local animal control in rescuing a pot bellied pig from a residential yard.  The pig is severely overweight, by my estimations, and we are in need of advice as to how to quickly but safely get some of this weight off so she can be more comfortable.  She is huge and can barely walk. She has huge fat forehead/brow that obstructs her vision so she is basically blind.  When we picked her up, we were given a bag of corn as her food.  Right now, that is all we have but know she needs some kind of balanced pig feed.  We would like some recommendations on what to feed her and how much to start out with.  She now has free grazing range in a small, 1 acre paddock with some rescued mini-horses and donkey.  Is grazing on grass enough for her right now?  She has no access to their feed at feeding time.  Any advice you can give is appreciated.  Thanks in advance.

Answer
Hello Lorie,
Actually letting her graze on grass is not the thing to do.  Grass can be very high in protein and encourages weight gain and hormonal growth.  
The best feed to help get her to a normal weight in a safe way is Infinity Plus.
You can order it on the Royal Dandie web site on the product page.
If you write to me from that web site and let me know her weight and age I can advise you further.
Good luck with her.
