Een paar conclusies:
After recording the characteristics of these horses' feet, Hampson then aimed to determine if their foot types could change. He caught 12 horses (six from rocky terrain and six from sandy), radiographed and photographed their feet, and then swapped their environments. He tracked the rocky environment horses via GPS for six months (800 km traveled) in a sandy environment and the sandy environment horses for four months (1,016 km traveled) in the rocky environment. What he discovered was that foot type does depend on environment (e.g., substrate hardness and distance traveled), as both groups of horses' feet changed completely during this time period to match the new host environments.
Hampson also discovered a high incidence of laminitis in four study areas around Australia. Of the euthanized horses he radiographed:
- 67% of 15 rocky terrain horses were laminitic;
- 40% of 15 sandy desert horses were laminitic;
- 93% of 15 prime grazing terrain horses were laminitic;
- 40% of 56 Kaimanawa region (New Zealand) horses were laminitic.
Hampson ultimately concluded there is no one natural foot type in horses and, contrary to popular belief, feral horses are not exempt from developing laminitis. Also, "There is currently no clear evidence to support the use of the extreme feral horse foot as a model for equine foot care," he cautioned. Keeping in mind all horses are likely vulnerable to laminitis, Hampson proposed the following suggestions for horse owners:
- Maintain appropriate diets;
- Don't overtrim horses' feet;
- Try to avoid excessive hard surfaces; and
- Encourage animals to exercise more, such as by using feeding systems that require horses to move around or by housing horses in large paddocks.

Ik vond deze uitkomsten opvallend. Welke vorm voor een paardenhoef is nu 'goed' of 'slecht'? Dat hangt blijkbaar af van de omstandigheden en omgeving In ieder geval is het kennelijk niet persé zo dat wilde hoeven gezonde hoeven zijn.





Blijkbaar vormt de hoef zich naar zijn individuele behoeften en zijn specifieke omgeving. Het bijhouden is dan misschien vooral wegvijlen wat dreigt een té grote onbalans te vormen in de hoef. Dit in plaats van de hoef te willen vormen naar een bepaald 'ideaal'-beeld, waarvan nog maar de vraag is of het wel echt ideaal is.
Voor een deel is het denk ik ook de niet helemaal realistische wens die wij als mens hebben, om een paard in de wei te houden en er vervolgens graag mee op verharde en grintwegen mee te willen rijden. Dat is ongeveer zoveel als verwachten dat je op teenslippers een berg kunt beklimmen.... Het schoeisel is niet (nog) afgestemd op het doel.
Food for thought... Wordt vervolgd...
Bijschrift foto's Dartmoor pony's:
I live in a wet area
of England which is upland and has herds of feral Dartmoor ponies. Their feet
are always the same. Long toes, wall always below the sole all round, concaved,
thin walls, relatively high heels, flared and they trim by "wet weather"
trimming ie they flare and break off. To some extent though although they are
long and flared the feet seem to be self regulating in respect of growth.
They have a variety
of terrain which ranges from bog, mud, wet moorland, dry springy grassy
moorland, tarmac roads, stone tracks. They have abundant natural feed. They look
well but not fat. They do not seem to get laminitis although they could eat
24/7. They are sound.
