Over 100 kids die a year from playing near hay bales.
Between 1.6 million and 2.3 million bales per year over the last 10 years.
One acre of land can feed one person for a year. That acre of land can be reused to feed a person for the subsequent year.
That all depends on the size and type of bales you have, as well as the forage biomass of that field. Bales come in not just one size, they come in small square, large square, small round and large round bales. Forage biomass is also different from year to year, depending on current seasonal conditions (moisture, sunlight, soil) for your area.
an average of 17.0 million bales, harvested between July-November, each year.
50000
7,000,000 bales

If you just happened to buy a thoughbred and ride them occasionally, feed them like any other horse. Look at 'what are all of the kinds of horse feed'.
It depends on how often you feed it and what you feed it, and the subspecies/locality. It could hit 5 ft in it's first or second year, or not until it's fourth or fifth year.
