Zach said:we have big oaks and hollows and those small creek trees. I think pine trees could be of benefit if you got the time. I know weeping willows grow pretty fast and can get plenty big enough, are they poisonous wilters?
three interesting things on there, that I'm not sure aboutcommercialfarmer said:Oak trees may vary on species as to toxicity. In our location, what we call "black jacks" or scrub oak can be very toxic in the spring with the newly growing leaves and in the fall with the acorns. Tannins are the culpret and can cause stomach and intestinal ulcers, and kidney failure. In years where there is drought, it is a bigger issue. We don't graze our brush pastures during early spring or just after acorns have started falling. This protocol was developed due to actuall losses we experienced.
Fact sheet below on it.

On the left side of the web page below is pretty inclusive of toxic plants/trees to cattle.

commercialfarmer said:I believe some of the listed plants are not necessarily toxic at all stages or at all times. I haven't went back through the list, but like johnson grass/hay grazzer, it is very deadly with new growth just after being stressed. Otherwise, cattle mow it down with no problems.
I thought the site would be more informative for the plants listed stating more specifics, but does not appear to be.
We have TONS of oak on our property, from Black Oak to Pin Oak to Chinkapin Oak. No problems with health, yet. Missouri is a top state for cattle production, and you would be hard pressed to find property without oak trees out here.the truth said:Bulldaddy said:I am sure your intentions are good but "the truth" is wrong when it comes to acorn poisoning. My comments are based on first hand knowledge but do a little research and I am sure you will agree with me on this one. Here is a link to some good information on the subject: http://www.thecattlesite.com/diseaseinfo/195/acorn-poisoning There are lots of good shade trees for cattle and there is no reason to take a chance with oak trees. By the way, acorns are not toxic to deer or hogs.
Like I said, corn can poison them as well.. and from what I've read on overeating.. the same conditions are present.
In the long term, oak trees are best shade, IMO- again from a forestry degree holder. There are plenty of other faster growing options out there, but some oaks are fairly fast growing for their own rights.
Again, do as you wish, but I won't be discriminating against oak trees in our pastures.
