It's not bad, but as pigs should only consume a tiny amount of pellets (unless they are under 6 months) something that large would not be needed.
I am concerned about the food in the dish. It appears to be a pellet mix with seeds and other colored bits and pieces in it. Those are extremely bad for pigs. They cause obesity and choking hazards and make pigs into very picky eaters. Plain pellets are what pigs need.
That's pretty cool! My pigs would eat the coroplast and tape rather than the pellets though. lol
By the way, can't help but notice it looks like you are feeding seeds, nuts, etc for their foods? They shouldn't have those but rather a plain pellet food like Oxbow. Those mixed brands are low quality and bad for them as far as nutrition too.
