If they are sealed you are not feeding round bale hay, you are feed silage. Silage is fermented. And though people do feed it to horses I am not sure I would feel comfy with a huge round bale of it for two of them.
Not nessecarily - Haylege also comes completely wrapped in plastic, it is baled wetter then hay and dryer then silage. It is less fermented then silage. Haylege is completly safe to feed to horses infact it is made specifically for horses, my lot have large bale haylege in the field and are fed adlib haylege in the stables. Infact there are many medical advantages to feeding haylege over hay.
I know Haylage is not common in the US but it is perfectly safe to feed in enormous quantities.
I'd never feed actual silage as there is the risk of the horse contracting botulism. http://www.poloforage.com/haylage_info.htm
ETA - Our haylege lasts 2 weeks before going off, normaly my ponies (when there were 3) went through one in approx 10 days in the field.
In the UK It is more common to feed horses haylage then to feed hay. Infact haylage is far easier to get hold of, in my area haylage is cheaper.
