Before I go rambling about nutrition needs for young and old horses, let me tell you all horses are different.
Young horses, say, around 2-15 years old can stay on the same diet of grain and hay. The grain that is reccomended for horses between these ages is a brand made for horses of that age. They usually don't have artheritis in these ages, but like I said, all horses are different.
If you know your horse has artheritis I would recommend a suppliment that you would mix in with your horses grain. You can get it at your local farming market.
Horses 16+ need a grain that is made specially for older horses, that there bones are growing weaker and makes it easier during winter months.
Like I said all horses are different. If you have show horses they even have special grains for better performance.
Look into it.

Sometimes horses will eat their own feces. Foals (babies) do this to populate their digestive systems with helpful bacteria they need to survive. Older horses usually do this because they are missing a nutrient in their bodies or diets. Sometimes horses eat feces because they are bored, or starving.
