Fungi for livestock feed and medicine

I know there is a lot of research regarding the use of spent growing media being used as livestock feed (supplement) however, I am interested in the possibility of using not just the spent media but the actual fruiting body or mycelium as feed. This should serve as a high protein feed source? Also, what about using fungi as an antihelminthic for livestock? Management is key but there are times when some have to be treated. We have herbal options already and chemical wormers are largely becoming useless. In either case there are lots of options for delivery and preparation. Which fungi would be the best to start experimenting with? Thanks folks!

I know chickens really appreciate having access to mycelium to munch on, I don't know about the fruiting bodies, but hogs will eat those. I just guess it depends on what sort of livestock you're looking to feed. Omnivores seem to do good with it though.

Dairy goats, chickens, and rabbits are my main animals now and next year I'll bring hogs in again. My primary focus for this would be the goats.

Hey folks,
There are tons of studies showing that micro and macro fungi are beneficial to animal health (both wild and domesticated animals). Yeasts, spent spawn, mushrooms, pure mycelium, medicinal extracts, etc. have all been tested. Across the board, they show great benefit to animals. I would start by going to scholar.google.com and typing in the latin name of the animal and the words "fungi," "mycelium," or "fungal," etc. You'd be surprised by what has been researched.

Cheers
