I can't think of a better article at the moment to explain starch digestibility than this one. Yes I do agree with you about the sugar in oats and I would never suggest feeding it to a horse with cushings or ulcers etc. However the starch is very digestible in Whole Oats and therefor not bad.
I also didnt think for one minute your posting was saying Oats were not a good feed. I did however believe the "High Octane" statement was. Oats are at best 12% protein, Alfalfa usually around 14 to 20% so together not anything I would consider high octane, just a healthy balance, especially for calcium which whole oats is deficient. Hope this clears it up. Oats Part 1 James Welz
