Mana Mushrooms

This is a basic profile for dried brewer's grain. My interest is in using this material as a component for substrate formulation, particularly insofar as it has direct industrial symbiosis implications.

Ingredients 101

This site is a resource for determination of substrate components by chemical composition which may help mushroom cultivators, ruminant ranchers, and farmers with feed constituents better evaluate the relative values of their inputs. My hope is that re-thinking such relationship webs will add value for all constituents.

Of particular interest to me at this time were:

1) Peanut Hulls: 8 1.5 62
2) Brewer's Dried Grains 27 6 15
3) Brewer's Wet Grains 4 1 4
4) Corn 7 3 3
5) Grain Sorghum (Milo) 8 2.5 3
6) Wheat Bran 15 3 10

The numbers above (sorry their a bit mushed) represent Minimum Crude Protein, Minimum Crude Fat, and Minimum Crude Fiber, respectively.
1 is of interest because I developed a relationship with a producer of this byproduct in Massachussets, where I look forward to implementing if I can demonstrate success with the model.
2 and 3 of interest because of several relationships developed with brewers, ranging from local brewpubs and microbreweries in MA and CO, to regional breweries in Chicago, to Coors, based in CO.
4 is of interest because I understand, especially after seeing the documentary King Corn that it is the primary feed constituent in the United States
5 is of interest because I have been told it makes a great supplement for a sawdust substrate
6 is of interest because I currently use it as a substrate component, as recommended by Paul Stamets and others.

from the Pakistan Journal of Nutrition (2004), this is one of the best articles I have found on yield performance on different substrates. Although it is no substitute for some of the literature available in print, it’s a far sight shorter and free :)
