The problem with meaties is (from what I've been led to believe) they will eat themselves to death if you let them. There is documented evidence to the contrary in this thread, but if you ladle it out, they will typically eat all of it. My FF is about the thickness of thick oatmeal. It will NOT flow out holes cut in the bottom of a bucket. I take it by the scoop and "slop" it into a 4" PVC pipe with end caps, cut in 1/2, mounted to 4x4 support legs to keep it from tipping.
I don't have meaties... some are bigger pigs than others, but none of mine will eat themselves to death, so I can load up the trough and it will give them enough food for 2 days in a pinch. Typically I load it every morning and as you can see in the pic, there's generally some residue left by the next morning. I just re-load right on top of it, enough for ONE day, not two.
If you wanted to get real mechanical, I would guess you could make a trough like feeder with a mechanical top that would open and close at specific times to allow them to feed for say 15 minutes then close and reopen for another 15 minutes 12 hours later or at 12 hour intervals, then load it up with several days worth.
