My attempt at fermenting my pig feed

So I found a good source of naturally raised grains/legumes for my pig feed this year and after talking with the lady who brought the feed (and seeing pictures of her pigs) I've decided to try her method out.

It's basically as simple as mixing up the feed in a large enough container and covering the feed with a couple of inches of water. She uses a trough, I used a plastic 55 gallon drum with the top cut off. Every time you scoop feed out you give the feed a good stirring to keep the brew aerobic. I guess you can keep adding feed and water to the container as you use up what's already fermenting and turn it into a continuous process instead of a batch brew.

I've attached some photos and I'll embed a video of the breaker bubbling away less than one day after starting it.

So how do your pigs like it?
How would this compare to you sprouting the same material?

So far the pigs seem to absolutely love the fermented feed.

Around day 3 the feed took on a noticeable vinegar smell which I was told to expect. I've added another 3 bags of feed to the mix to keep it going and it's just bubbling away.

As far as how it compares to sprouting the feed I couldn't tell you, I've never tried sprouting the grains.
