Black walnut toxicity question...

A year ago we planted a black walnut tree in the area that we are now planning on fencing for Lyndsey's breeding ewes and our Angus/Hereford calf Carhartt. I have been trying to find out if Black Walnut is toxic to sheep and cows and keep finding conflicting info... I am thinking it is easier just to move it now rather than mess with it when it gets bigger. I am wondering if any of my blogging buddies know the answer?

Thanks!

  1. We use to have a large dairy farm in the mountains and black walnut trees were everywhere on the farm. No way to have a pasture without them in it somewhere. The cows ate the leaves, napped in their shade, and even tried to eat a walnut or two. Never had any problem. Not sure about sheep though.

  2. I know it can make for toxic soil conditions for things like mushrooms and such to grow, but don't know anything beyond that, looking forward to hearing from the others!

  3. No help here. We have (had) only one black walnut tree in the county (that I know of). It was a beautiful, HUGE, old thing . . . that the new owners of the property (get reading for this) cut down. :o[

  4. The only animal I KNOW of that can't have black walnuts (even the shavings) are horses. We have black walnuts around here, and we have goats, but there aren't a lot of them near the goat pen.

  6. I belong to a group for people who raise Nigerian Dwarf goats, and that question has been tossed around there. The consensus is that they cause no problems for the goats. I think that if it were possible to overload on black walnut, it would only happen if the animals had nothing else to eat. Of course, I don't have any black walnut trees here, so this is all second hand, and not my experience.
    Happy fencing! :)

  7. Will they even eat the walnuts? My sheep and cows seem to ignore the nuts and eat the young leaves. I know that if you powder the shells it is toxic to fish.

  8. Afraid I have no answer for you, but WOW I miss black walnuts. My dad would take us out to where these HUGE old black walnut trees grew in Chico, California, we'd pick bags full, then smash them on the garage floor with hammers, getting the little bits of meat out. THEN my grandmother would make zucchini bread w/black walnuts. 10,000 times better than English walnuts. And, at least here in CA, they're native, and since I'm a conservation biologist, that makes me happy.

    So, now you've inspired me. I wonder if I can grown one or two here?
