What are the correct ways to use Wuliangye distiller's grains

Corn, miscellaneous meal and other raw materials are very expensive now, and I want to use baijiu distiller's grains in meat duck feed. The baijiu distiller's grains are very black in color, have a strong liquor smell, and contain 23% crude protein. Does the liquor smell have any effect on duck feed, and what amount is appropriate to use? Experts who have used it, please share more opinions.
---------------------
Is the distiller's grains everyone generally uses beer distiller's grains or baijiu distiller's grains
?
Confused
---------------------
There are beer distiller's grains produced by breweries, and also baijiu distiller's grains such as those produced by Moutai distillery and Wuliangye distillery, but beer distiller's grains are commonly used, while baijiu distiller's grains are rarely used.
---------------------
I have never heard of using baijiu distiller's grains either
