Horses can choke on anything. (when was the last time you 'choked' when you had a swallow of soda) Feeding from the ground, grazing position is better for normal wear and tear on their teeth.
Bolting food is the most common reason for choke.
If you can get the horse to relax and massage their throat, many times the obstruction will resolve without having to be tubed. Depending on the severity of the choke and what the object was - the horse may need an anti inflammatory and or antibiotics.
