strawberry plants and cattle

Hi  all,

Does anyone know anything about feeding strawberry plants to cattle?
A local a strawberry plant producer wants to know if he can use
strawberry plant culls as cattle feed. He grows the plants as root 
stock, but the sorting process results in considerable 
quantities of culls. He would like to know if there are any reasons 
why these plants can't be fed to livestock.  Are there any bioactive 
compounds in stawberry plants that might be detrimental to cattle?

As usual, any and all help is greatly appreciated.
