How to Keep Colonic Ulcers in Check

natural horse calmatives

Colonic ulcers, or right dorsal colitis (RDC) for a better term, is quite common amongst performance horses in particular, but has been known to affect non-performance horses as well. In a study involving 545 horses, 44% nonperforming horses tested positive for RDC while 65% of the performance horses suffered from colonic ulcers. Which raises the question, why are performance horses more susceptible and what can you do to prevent colonic ulcers?


What are colonic ulcers?

It’s a painful, medical condition involving the development of ulcers in the large intestine of your horse, also known as right dorsal colitis (RDC). This condition decreases nutrient absorption and increases protein loss. Elevated stress levels play a big role in the development of RDC and it is closely related to the use of anti-inflammatories. Performance horses are more affected due to their particular lifestyle – travelling for extended periods of time without constant feeding opportunities and stressful competition participation.
