I am a grad student currently working on an oyster mushroom cultivation project in the North Atlanta Metro area. I am growing oyster mushrooms on regional agricultural waste (corn chaff, spent brewing grain, cotton gin waste, and peanut hulls). In my readings I have come across the idea that many types of livestock will eat spent mushroom substrate. Do any of you have experience with this? I do not have any livestock of my own. I am producing a lot of the spent substrate and would love to see if livestock will actually eat the stuff.
