Glyphosate and Equine Ulcers
My post a few days ago seemed to resonate with a lot of people who have noticed the increasing trends in the metabolic health of our equines and the increased presence of glyphosate in all aspects of the lives of our animals (and ourselves).
People also noticed the increase in other immune related issues related to things such as EPM, Lyme, sweet itch, hyperreactivity to vaccines, and overwhelmingly- gut health issues.
Unfortunately even though so many people have stories about how they have witnessed health decline in their horses when exposed to glyphosate, there are almost no equine related studies that we can reference.
BUT... there is one! (Link in comments)
Schusser GF, Köller G, Recknagel S, Lindner A. (2022). [Glyphosate detection in the duodenal fluid of horses with gastric ulcer syndrome]
This shows a connection between the presence of glyphosate in the duodenal fluid of horses and gastric ulcers in horses.
In my own experience, i have seen subclinical and chronic lamintis symptoms in horses with gastric ulcers. I can often see the quality of the feet, presence of repeated stress lines, sole depth, posture and overall comfort in the feet, whether or not a horse is suffering with ulcers.
I'm unsure if the cause of those hoof changes are due to chronic systemic inflammation, poor nutrient absorption, bacterial die off or imbalances in the microbiome causing a toxic systemic reaction or all that and then some? But if this study is correct, and glyphosate can be connected to the presence of ulcers, that is another connection between glyphosate and hoof health.
Once again, not implying that glyphosate is the ONLY cause of ulcers, there are so many things that can contribute, but the case is there and we need to informed. I promise my page won't turn into all glyphosate, all the time, but while I am educating myself more on the topic I may as well share!
