You need to start with a basis of
good quality GRASS hay. Horses do not need grain unless they are being worked hard and their weight cannot be kept up with hay only. I especially would not give grain to a horse that is severely underweight.
Equine nutrition is complex and depends upon what you are feeding, pasture and where you live as that will determine what nutrients they are or are not getting from grass or hay.
An excellent,
comprehensive book is Storey's Guide to Feeding Horses.
Also, you say that your horse is severely underweight but that can encompass quite a bit of area. Since you are obviously online, type in "horse body condition score" and check out a few sites so that you can see how bad your horse is. If she is a 3 or less, get your veterinarian involved. You can kill a severely underweight horse by trying to put weight on them too quickly.
I know I have not directly answered your questions, but I hope I've helped you a bit.
I bought a mare years and years ago that had a body score of less than 2. I put her weight on by feeding her hay only at first, then a supplement that you only fed 1 oz of twice a day. I put that in a handful (literally what I could pick up in one hand) of oats.
The horse I have now (who is in good condition) gets hay morning and evening with Triple Crown 30% supplement & 1/2 cup of whole flax seed & (for the last year) a joint supplement. I also give him warm beet pulp (pellets soaked with warm water) in the winter. Anything that you give your horse as a supplement needs to be given in small amounts at first and then worked up to the recommended amount. Also, if you change feeds or even hay, you should change them gradually from one to the other.
