One of my friends recently took in a malnourished horse from an elderly neighbor who just couldn't take care of her anymore. Right now the horse is just grass fed, but is there a little something extra the horse should have to boost her weight?

In the past, I've tried a supplement called Weight Builder that seems to work really well. It will add weight but doesn't give them any more energy and it's safe for horses. The horse I gave it to loved it.
You can purchase it at www.smartpakequine.com (http://www.smartpakequine.com) but you may want to check with your vet first.

I wonder if there are there other things you could add into the horses diet too, a certain vitamin or two maybe that will help.
