I don't know about the variety you have Kenny, but in La, they grind the crushed stalks at the mills and turn them into what they call bagasse. Most is used for fuel in boilers at the mill.
The stalks there traditionally had hardly any leaves as the stalks were cut, laid down in long rows and then burned to remove the leaves but more modern methods use a combine looking machine to harvest the whole stalks, separate them from the foliage, cut them into short pieces and shoot them into a hopper.
Sometimes, they burn the fields with the stalks still rooted then harvest it.
Cows probably won't eat much of the stalks because it still contains some sugars and sours pretty quickly.
If it hasn't been heat treated, there is a very good chance you will have cane coming up where ever you feed it. Each joint of the cane is capable of producing a new plant if it is planted or even in contact with the ground.
