Are there harmful effects of a horse that’s hooves come in contact or eat the leaves? I know the details of he shaving problem but am failing to find info on the leaves on ground.
I have a few black walnut trees in my pasture and have never had a problem. Of course that’s not an official answer, but it’s been 15 years so far, so I feel pretty good about it. I’d love to get rid of the trees but it seems like it’s more dangerous to cut them down than to leave them there.
Nope, don’t believe that leaves are a problem at all. There are many horse pastures across the country that have many black walnut trees in them without a heal issue for the horses.

Depends on if horses stand in leaves of any depth, how long, if they are wet to leach out the jugalone which is the toxic substance in Black Walnut.
Just a couple leaves, stand on for short times on a dry day, dry ground, probably not a problem.
Deep leaves, wet season with mud and rain getting horses hiding under Walnut trees, could get some jugalone on the hooves to be absorbed. So it would be similar to standing in Black Walnut sawdust to those hooves. That would be BAD, hooves WILL absorb thru the walls, soles, any jugalone in leaves or sawdust. Any and ALL parts of Black Walnut trees contain jugalone, that toxic substance.
A friend took some sawdust from a wood worker friend, used it for stall bedding and had horse reacting BADLY within 12 hours. She called to ask about him working Black Walnut so it could be in there and he said yes. “Not much though”. Managed to prevent Laminitus, but it was close. Just absorbing jugalone thru the horse’s hooves caused that.
Couple leaves under the hoof for shorter times are unlikely to be an issue. Horses tend to avoid the leaves of the Black Walnuts, not so much chewing on the trees either, if horses have other good food available to them in a pasture situation. Just like they “tend” to avoid poison plants if there is good stuff to eat in a field.
As mentioned, lots of pastures with Black Walnut trees, never had any horse issues with that. But knowing to watch for possible problems is always wise, catch things early and prevent problems. There will ALWAYS be the “exception” horse who didn’t read the book about avoiding problem plants, wants to die or cause you MUCH grief.
I really do appreciate the info. Tacked up. Got on. Walked a few steps and damn near fell down. Repeated a few times. Got off. Re adjusted boots. Rye picked hooves. Could barely turn to go in stall. Pinched. Poked. Palpated. Nothing. Missed hot pulse…my bad. Vet came. Slight laminitis doing much better today. Started to rewind everything we could think of and she was reshot a few days ago and we do have several BW trees but not in their eating reach unless she absorbed through fresh soles of ate leaves. It’s looking good and she’s doing real well. Thank you all again. Could be just another horse mystery.
Anything more?
Only the Wood of BW is the Toxic part ~ not leaves ~
* PSA this post is wrong !!!
please read post #8 goodhors ~ I was wrong ~ I apologize apparently mislead by some kooks in my area !
Only the wood is toxic :eek::yes: according to all the experts (vets…)in my life.
Pastured horses with groves of black walnut trees throughout the Midwest no problems ~
- but shavings with black walnut will founder them ALL within hours / toxins absorbed through the feet // a padded shod horse will be foundered at a slightly and only slightly rate but I have seen padded horses spared due to the time delay ~
:eek: Black walnut shavings are something AWFUL & Tragic and honestly should never ever even accidently be near horses !
Jingles for your horse ~ ((hugs)) for you !
Sorry Zu Zu, the Black Walnut leaves ARE toxic, because “all parts of the Black Walnut Tree contain Jugalone”, the chemical which is the problem.
Mentioned here specifically in paragraphs 4 and 5:

A good short article on Black Walnut toxicity in the tree and area
around tree affecting other plants. Some can tolerate the jugalone,
while other plants will wither up and die. Very informative.
OK Thank you for this ~ I have been mislead for years ~ THANK YOU !
Thank you ~ apparently I have been mislead for years !
But I am glad to know this … and grateful that we do not have any Black Walnut trees in our horse areas …
goodhors Thank you for taking the time to educate me ~ appreciate this immensely ~
I’ll correct my post ~
