Upon request I am starting a thread about using fermentation to improve feed nutritive value and health benefits.
- Anyone doing it?
- How long have you been doing it?
- Your methods?
- Grains/feeds used in this manner?
- Your overall review of this method of feeding?
In the spirit of sticking to topic....

(For those like me who would have to look it up or ask..."UP/ACV" = Unpasturized Apple Cider Vinegar...[and get the one with "the mother" in it].
1. Yep.
2. Not long...couple weeks maybe
3. I have a large plastic coffee can that I was tossing kitchen scraps into daily. It started to smell horrible and I needed a solution. [Fast forward through a lot of details about how it all came together...I tend to get long-winded so I omitted this for the sake of brevity.] So...my method started out with 4 plastic cups worth of scratch grains (aka bird seed with "extras")...maybe about 6 actual measured "cups". To that I added some rolled oats we had laying around, some "quinoa" that I snuck in for fun, and beans and whatever else. [NOTE: It doesn't matter how much you start out with...this is not a lab experiment and you won't get a grade.
)
I dumped in a gloggle of the UP/ACV (maybe 1 tsp...maybe more) and covered all the stuff with water and mixed. It sat overnight, and the next morning I fed my chicken 1/2 of the contents. Immediately after feeding the chickens, I replace whatever I fed them with fresh grains, so I end up with a bare minimum now of 1) some old stuff and 2) the rest of the stuff that has soaked and fermented for 24 hours. I just repeat each morning...feed 1/2 of what's in there (along with kitchen scraps that I now sit atop the seed mix) and leave the other half to continue fermenting and provide the fermenting agent for the new grains.
4. So, far, scratch grains mixed with whatever amount rolled oats, beans, etc...that I can sneak out of the pantry. But now I want to toss in my layer pellets as well...if it turns out that this is okay.
5. I am thoroughly satisfied with this.
First of all, my kitchen does not stink because the coffee can, that used to smell up the kitchen with "rotten scraps odor" is now neutralized with the ACV. I smell NOTHING unless I stick my face inside the container...and even then it's not a terrible smell at all. (I wouldn't wear it as cologne...but still... )
Second, I can tell a difference in digestibility of the grains. When I first started to feed scratch grains (dry) and other seeds to my chickens, I could see the seed mixed into the poop. Now, I can't. It's that simple.
