Ok, im confused (please bare with me). If oats and barley ect are fine and natural to feed horses, then why does research say that grains and starch are bad for horses? How come they cannot be digested properly if they are meant to be good? I do get confused by oil as well because I don't really think horses eat oil in the wild..
My guess is that horses in the wild would only eat seeds when they are in season, and they would be eaten with the long stalks of grass that accompany them, so I wouldn't imagine horses would eat many wild oats, even in season, compared to what they are fed today.
Cereals in their raw unprocessed form aren't very nutritionally available to the horse, and due to the structure of the horse's digestive system, many of the nutrients in them wouldn't be absorbed - that's why we have cooked and rolled and otherwise processed horse feeds, because feeding them the way nature provides isn't very economical to the horse owner. The trouble with processing them is that suddenly all this starch IS available to the horse - and if fed in high quantites and/or in an unbalanced diet, can upset the fermentation of fibre in the horse's hindgut. Fibre is what the horse has evolved to live on, and a diet lacking in fibre has welfare issues such as stereotypies/vices and ulcers.
There is some oil in many of the feedstuffs the horse would eat naturally, and the horse has been found to cope quite well with diets containing a reasonable amount of plant sources of oil (up to 20% I think, if my memory serves me correctly? But if you feed over 10% good luck convincing your horse he wants to eat it...).
The arguement for feeding horses higher amounts and different types of things which wouldn't occur in the horse's natural diet, is because we ask him to do more work and to live a lifestyle which he wouldn't do in the wild. Therefore, research (partcularly that funded by the racing industry, which has a high level of demand from the horse's diet, and encompasses a high % of research which goes on that you and I benefit from eventually. Its not perfect for leisure horse owners, but better than being based on cows, which some recomendations for horses still are! Again, we are making best guesses based on the available research, which is dictated by who will fund what, and funding is usually only available if there is a commercial interest) tends to look at what the horse will tolerate, rather than whether it would occur in nature. It seems to have come full cycle now and people are starting to think about the full effects of feeding, and many are coming back to trying to have as natural as possible a diet for their horses.
Personally, I'd rather people fed a feed based on feed company recommendations (which are usually based on some sort of knowledge and research), rather than do something "more natural" if they don't know their equine nutrition. I think the evolution in feedstuffs is a good thing, and as with anything else, we can't all be experts but as horse owners we have a responsibility to educate ourselves as far as possible, and to make the best decision we can for our individual horses.
