Horses kept in stables for significant portions of the day face welfare challenges from social isolation, limited movement, and inability to perform natural foraging behaviors.
The modern horse husbandry model of individual stabling, twice-daily feeding, and limited turnout is the opposite of the horse's evolved social and behavioral needs. A horse evolved to graze with a herd for most of its waking hours cannot be adequately compensated by two hay feeds, two hours of ridden exercise, and social isolation. Gastric ulcer prevalence in performance horses reflects the physiological cost of this management mismatch.
