Re: buckwheat and chickens

Can buckwheat be used for sheep forage also?

I can imagine using the buckwheat to renovate a pasture or grain field... 
 let the sheep eat down the current plant cover and trample in the 
buckwheat seed, then after the buckwheat has done it's work, use the sheep 
to "harvest" the buckwheat & also trample the seed in for the next crop... 
anybody tried such?
