Should you feed your horse grass clippings?

Fresh grass clippings may cause choke as they are damp and will ball together in the horses mouth and esophagus when it swallows. If the mass makes it down into the stomach it may be hard for the stomach acid to break the ball of clippings up and it could pass into the intestines intact causing a blockage and colic, which may require surgery. Another factor is chemicals from the lawn mower possibly leaking out unnoticed and then poisoning the horse when it eats the grass clippings.

If you wish to feed grass to a horse, simply pull it up by hand and give it as a treat, or let the horse hand graze in areas where it is safe to do so.
