Leftover Mushroom Growing Waste Makes Safe Animal Silage

Leftover Mushroom Growing Waste Makes Safe Animal Silage

Oyster mushroom, Shiitake

What they found

Silage of 70% spent oyster or shiitake substrate and 30% corn was up to 74% digestible and free of mycotoxins.

Feed From Fungi

Scientists tested silage made from mushroom waste—spent substrates of oyster (Pleurotus ostreatus) and shiitake (Lentinula edodes) mushrooms—mixed with corn. The best mix was 70% mushroom waste with 30% corn, which had good smell, color, and digestibility (up to 74%). Shiitake-based silage held more phenolic compounds (8.2–9.0 mg GAE/g DM), while oyster-based silage showed faster fermentation. Importantly, no mycotoxins like aflatoxin or ochratoxin were detected, confirming safety.
