Arthritis is the nightmare of every horse owner. The diagnosis often means the end of a sports career or at least massive restrictions. But arthritis is not just "wear and tear" that happens by chance. It is an inflammatory process that we can influence massively through husbandry, training, and targeted nutrients.

In modern veterinary medicine, we no longer understand joints as rigid mechanics, but as living organs that are constantly being built up and broken down. If the breakdown occurs faster than the buildup, arthritis develops. Here are the scientific levers to shift the balance in favor of your horse.

1. Biomechanics: Hoof Balance is Everything

Before we talk about feed, we have to talk about physics. The hoof is the shock absorber of the horse. An unphysiological hoof shape (e.g., toes too long, underrun heels) changes the leverage forces in the entire leg.

Studies show that even slight misalignments multiply the pressure on certain joint areas. This leads to "microtrauma" in the cartilage. A competent farrier who maintains natural balance is the most important arthritis prevention you can practice.

2. Inflammation Management: Extinguishing the Fire

Arthritis often starts quietly with inflammation of the synovial membrane (synovitis). This inflammation releases enzymes that attack ("eat") the cartilage.

The Role of Nutrition

Many horses today receive feed with a high proportion of Omega-6 fatty acids (from grains, corn, soy). Omega-6 promotes inflammation. Natural feed (grass), however, contains more Omega-3.

  • Omega-3 Balance: Supplementation with high-quality Omega-3 (e.g., from algae oil, as plant oils like linseed oil are inefficiently converted by the horse) can help lower systemic inflammation.
  • Senolytics (Fisetin): Recent research suggests that so-called "senescent cells" accumulate in old joints. These cells no longer divide but send out inflammatory signals. Substances like Fisetin can help eliminate these cells.

3. Movement: Use it or Lose it

Cartilage has no blood vessels. It is nourished only by "diffusion" – that is, by alternating loading and unloading, which pumps nutrients into the cartilage like water into a sponge. A horse standing in a box for 23 hours starves at the joint level.

The Golden Rule: Plenty of free movement at a walk (open stable, paddock trail) is ideal. Cold starts in training, however, are poison. At least 15-20 minutes of walking before work is mandatory to make the synovial fluid liquid.

Conclusion: Act Instead of React

Don't wait until your horse needs to "warm up" or the first X-ray findings are there. Arthritis prevention begins with the young horse. Through correct hoof care, anti-inflammatory nutrition, and appropriate movement, you can significantly extend the "healthspan" – the healthy, rideable time – of your horse.
