POISONOUS PLANTS

I have known people whose horse died mysteriosly. I suspect poisonous plants. With my first horse many years ago I cleared out all the vetch in her area. Then I saw a kid picking the vetch outside her fence and feeding it to her. I explained to the kid that the plant was poisonous and told him not to feed it to her. Vetch will not kill immediately but the effects are cummulative and will injure the horse eventually.

Later I saw my horse's nose swell up. There were just a few yellow star thistle plants in her area but she must have found them and they taste good to horses. I pulled the few plants - they come up easy and my horse was back to normal.

Black walnut heartwood is toxic to horses so don't use the shavings for bedding. The green hull of the nut may cause kidney failure. But it is not necessary to keep a pasture free of black walnut trees.

Most poisonous plants do not taste good so horses will avoid them unless the horse is very hungry. Learn about the poisonous plants in your area and get rid of them in your horse's pasture and save your horse's life.
