## Resource

Horses graze on grass and plants, not trees, because their digestive tracts—shared by equids, tapirs, and rhinoceroses—cannot digest wood. Unlike ruminants (cattle, deer, goats), they avoid lignin.

The goal of this podcast is not to make you plant and tree experts, but to help you appreciate two key principles of horse care: always provide adequate protein and forage, and proactively remove any potentially harmful vegetation before curious horses can reach it.
