Help!  I need some advice on how I am feeding my mare.  I am getting some VERY conflicting info here at home.  I can't figure out if this advice is coming from knowledge base or profit base.  Since I know many of you are quite knowledgable about this topic, I turn to you. Right up front, please forgive my ignorance (I hope my mare does too).

She is a 9 yr Trekahner, training for her first ride.  Her weight is approx 1100-1200 lbs, you only see some rib when she is working.  She gets a good size flake of alfalfa 2x a day (ranch supplied - obtained in Southern Calif) and 2-3 flakes of oat hay supplied by me a day.  I feed oat hay so that   a) She has some forage between feeding times
			b) an attempt to offset the alfalfa

For grain, she gets 1/2 lb of 606 and 1/2 lb of senior feed because this is what she was raised on and I didn't want to change EVERYTHING when I bought her.

I am mostly concerned with providing her forage (we have no grass pastures available) and keeping her clacium/phosphorous ration healthy.

What do you guys think?
