About this episode

This episode discusses common plant and tree toxins that can affect horses in North America and emphasizes the importance of proper horse care.

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. When starving, however, horses may eat almost anything, which is why some plants and trees become toxic. 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. Your horse's health depends on your attention to these crucial details. ******************************* #horses #veterinary #horseteeth #horsecare #equinedentistry Join us at The Horses Advocate Community page : https://community.thehorsesadvocate.com/yt Dentistry : https://theequinepractice.com/ Horsemanship Dentistry School: https://www.horsemanshipdentistryschool.com/c/information/ Facebook : https://www.facebook.com/TheHorsesAdvocate Instagram : https://www.instagram.com/horsesadvocate/ Geoff Tucker is a veterinarian and horseman who has worked with horses since 1973.
