Learning about gastric ulcers and pH levels
After Kobeejo colicked (a strangulated lipoma, which is unpredictable and unpreventable) and they also found ulcers in his stomach, I decided I needed to look into this further. I have always been a huge fan of 24/7 forage and no grains (just a ration balancer) and was always taught that this would prevent ulcers in horses. Even at the vet hospital, I asked them "How can a horse on 24/7 free-choice forage get ulcers?" They had no answer. The head of veterinary medicine even said to me, "Everything I would normally tell you, you already do." So, as is my habit, I began to research... a lot! pH Levels in the Stomach: The normal "cut-off" for equine intestinal pH is >4.0. Neutral is 7.0. So 4.0 is acidic. But, in the bottom layer (glandular), pH levels are naturally going to be low because that is where hydrochloric acid is produced and stored. Kobeejo's ulcers are located, typically, in the squamous (upper, or non-glandular) layer of the stomach. ...
