The cows graze on the short grasses at the ground.  They ignore the tall  
stuff with the seeds on it.  I don't keep cattle, but my brother does, and  
he cuts the fields if they get too tall, because the cows won't eat the  
tall grasses and they wind up poking themselves in the eyes trying to get  
to the short stuff on the ground.
