New pasture question

[Carnivore]

I am just finishing fencing about 10 acres, and it is a combination of grass, brush, (which includes many different species of things cows likely don't eat) and some fir trees. While I would like to kill it all off and plant a nice grass, the cows are getting hungry, and I want to get them on it, to give my other pastures a break. I will kill off what the cows don't eat when I bring them off of it after they eat all the grass. My question is, is there anything I need to worry about the cows eating that might cause them problems, or do they do a pretty good job of selecting what is edible? Perhaps a dumb question, but one that I need answered anyway. Thanks.

There are a lot of things that "could" be harmfull, but if there is anything else to eat they'll normally avoid them. Bracken fern comes readily to mind. Castor bush/tree is another. Not sure if it's harmfull but you don;t want to be within 20 feet of the rear of them if they start eating it.

Thank-you dun. Gives me an idea on how to proceed.

Cherry trees can be a problem. Cattle can eat green cherry leaves without any problem, but if the wind blows a green limb down and the leaf withers, that is very deadly. I try to take out any cherry trees in my pasture just to be safe.
