Spent Oyster Mushroom Substrate as Feed for Livestock?

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.

No experience here,  but I am interested.
Like you said there is at least one study out there on this.
I went looking for it when I realized that oyster mushrooms eat the one thing that keeps wood from being digested  by cows.

I hope you get some answers or at least some more replies.

Thanks William! Yes, my understanding is that the oyster mushroom can make the lignocellulosic material easier to digest and increase the nutrient uptake by the animal.

We have a lot of chicken in Florida. Im curious from the opposite end of the spectrum. I want to grow oysters and am wondering if I can feed it to the chickens. Its a shame we don't live closer!

I am curious about pigs and goats as well. What an amazing way to turn waste in to two valuable forms of protein.

I would love to connect.

I would like to add that one ways to "crack" (quite literally) cellulosic ethanol production it to break open the cellulose with mycelium. Food for thought.

My quail adore mushrooms! I don’t know about the substrate though.
