I would reccomend option 1- but I would change it just a bit.
Alfalfa hay cubes and grain, with free choice hay/grazing
. In addition to the roughage, I would like to add a top dressing of Equine Choice probiotic mix to maintain proper gut movement and beneficial bacteria, and HorseSTART mineral supplement for pleasure horses.
Mine (note: it is written as if I were you- this is not my plan
): the season and how often I ride would determine how much alfalfa/grain I feed , for example, in winter maybe a little more afalfa, and in summer maybe because you have more riding time(and at least here the grass dies). I would be careful with feeding the alfalfa, and wont feed more than about the equivalent of half a flake. (I only feed my horse half a flake of alalfa when she works hard!).
In addition to the roughage, I would like to add a top dressing of Equine Choice probiotic mix to maintain proper gut movement and beneficial bacteria, and HorseSTART mineral supplement for pleasure horses, but would be careful with mineral usage in spring and fall, espically spring,(but grass DOES get green in fall to!) as the grass has more nutrients in it.
I hope it helps! And well, don't feed to much aflafa as #1 as you might know some horses don't process it as well and therefore get "hot" from it. #2 its quite high in calcuim- therefore good for younger growing horses and broodmares- and basically has no phosphorous, which can be very detrimental to the horses health. Oh and, be careful with those probiotics, make sure it isnt like chemicals- try to be as natural as possible for your horse.
