Spent Grains

[Voodoo 6]

Every morning when I pass the brewery, I see this guy pulling a horse trailer behind an old truck loading up 55 gallon food barrels from the brewery. I am assuming these are the spend grains.
 
Does anyone know what uses spent grain has? Do they use it as feed? I am hoping not because there is probably zero nutritional value left after extracting the sugars. Any thoughts?

Maybe compost?

Animals eat it. I think they mix it with oats and other stuff too.

I threw my spent grains in the garden this year. No idea if the the plants benefited from this but it didn't seem to do any harm. Appears to break down quickly...

It can be made into bread https://www.homebrewersassociation.org/how-to-brew/bread-from-beer-grains/

wonder if there is any nutritional value to spent grains, have to look into that. if there is no value to it wouldn't it be like eating saw dust?

I use to give mine to a pig farmer, he would bring me a few roasts when he would slaughter one. Much better than just throwing it in the compost bin.

"The protein concentration and high fiber concentration of spent grains support rumen function and animal production. Wet spent grains are a good source of protein with a crude protein content that ranges from 25-34%."

Thanks! Some good info here.

It doesn´t surprise me that there´s still a decent amount of nutriment left in spent grains; mashing and lautering are intended to extract converted starch as well as some flavor, aroma and color, but they aren´t intended to get every bit of nutritional value out of the mash...
 
I used to homebrew a lot. I just wasted my spent grains.  Now that i keep some wormbins, i´m kinda curious how it would do as worm food....

Was reading that blackhog brewing trades their spent grains to local hog farmers for a whole hog for their annual roast.

All the meats here sold in the supermarkets are really fatty. I remember meat back in the day being much leaner. So I was wondering.
