The feral horse foot. Part B: radiographic, gross visual and histopathological parameters of foot health in 100 Australian feral horses.
Hampson BA, de Laat MA, Mills PC, Walsh DM, Pollitt CC.
"Lamellar samples from 15 feet from three populations (of feral horses) were investigated histologically for evidence of laminitis .... Of the three populations surveyed by histopathology, the prevalence of chronic laminitis ranged between 40% and 93%......
CONCLUSIONS:Foot health appeared to be affected by the environment inhabited by the horses. The observed chronic laminitis may be attributable to either nutritional or traumatic causes. Given the overwhelming evidence of suboptimal foot health, it may not be appropriate for the feral horse foot to be the benchmark model for equine foot health."

Histopathological examination of chronic laminitis in Kaimanawa feral horses of New Zealand.
Hampson BA, de Laat MA, Beausac C, Rovel T, Pollitt CC.
The left fore feet of Kaimanawa feral horses (28 stallions and 28 mares aged 6 - 12 years) were examined. 45% were diagnosed with chronic laminitis. "The finding suggests that horses are vulnerable to laminitis whether in domestic care or in a feral habitat."
