Ah, okay, so it's fine for larger pigs but can upset the smaller ones?

I wouldn't say "fine" but rather "less bad" instead. It can reduce growth rates in sufficient quantities.

VERY important topic! I am glad you made this answer! Only ruminants are less affected by fungi.

Molds can also lower the quality of the meat for US to EAT, or even make it toxic. The difference between "less bad" and "deadly" is the quantity. In all cases, it gives a lot of work to the liver and the lymphatic system, and some mycotoxins will be in the meat. Some people are genetically less apt than others to clear mycotoxins, thus the issue of "toxic balck molds" in buildings that can affect some people more than others.

Molds in food is definitely an issue, and this is why people from the wet tropics invented the WOK for cooking! As long as they stll use coconut oil, it helps sterilize the affected food even before the molds get visible. And mycotoxins are the worse, they are invisible. By the way, alcohol is the MYCOTOXIN produced by the fungi used in fermenting. Not all mycotoxins have the same toxicity. Some can even be favoring cancer.

I more and more considere that molds are an under-stated threat for all living beings, plants or animals. And the use of fungicides can lead in the future to the same type of problems as antibiotics did.

anyone have experience in fermenting slop for pigs- would these make decent substrates?  the spent grains aren't that valuable for a monogastric digestive system-would fermenting bump up the availability?  
alternatively considering using the spent grains as a substrate for wine cap mushrooms.  
Thanks!  Kris

Kris, are you by chance near Stevens Point/Wausau?
