thinkstoomuch - 11/27/2024 12:02  I am worried about bad arguments given as truths to justify anything. Like my envelope math above. Distiller's from 1 bushel of corn makes 0.1 lbs of edible beef. That is a close to truth calculation, but highly defies "but we get ethanol and 18 pounds of distillers grains per bushel" statements implied value



Your "envelope math" is highly flawed in multiple places and nowhere close to representing the true value of ethanol/DDGS.

The remaining feed from a bushel of corn run through an ethanol plant is 18 lbs of DDGS.     Do you know what DDGS is?    I ask because your envelope math says that you do NOT know what "DDGS" is.   DDGS stands for "Dry Distillers Grains with Solubles".   Its roughly 12% moisture, meaning its 88% Dry matter.

Who converts their meat consumption to dry matter?????   BTW, beef is ~70% dry matter, not 70% water.



Ok so adjust my numbers from 60% moisture from wet distillers discussed to 10% moisture and edible beef dry matter per bushel of corn .jumps to almost 0.2 lbs per bushel of raw corn used for ethanol. And I didn't deduct bone and other non consumables of retail beef.i also didn't research my number far enough to recall that is dry distiller per bushel.

The moisture content of beef come from basic research documents.

If adjusting out water to the food equation adjusts to the place all food on par. Protein. Fat, and carbs are the only means humans extract food value and most other foodstuffs are low moisture. I would like to sell corn silage if dry matter content didn't matter.

7:1 feed to gain ratio was a bit of a backhand number. I discounted general DMI to intake and probably didn't adjust low enough to account for parturition nutrient consumption. This would need to swing widely to get result of edible beef much higher. I also lacked a quick adjustment to account for protein contribution to energy utilization efficiency.

So let me know where my numbers are flawed. Good numbers are the goal.
