I know humans cannot completely digest sweetcorn; are there any animals that can?

Answer 1

No mammal can digest cellulose without help; and it's the cellulose in sweet corn that we can't digest.
Some mammals, notably cattle, have a complicated digestive system which hosts an abundance of cellulose-digesting bacteria. These are the animals that live mainly on grass, which is mostly cellulose and pretty much indigestible to us. Once the cellulose is broken down into starches, the cow can digest it and also digest a lot of the bacteria, as a source of protein. Cool, huh.
So basically herbivores that favor cellulose, such as grass eaters, should usually be able to do the job.

Answer 2

It is only the outer seed coat that you can't digest, the rest of the grain is both digestible and nutritious. Because the seed coat is composed of cellulose it will not be digestible by any anything but animals such as cows and horses that have symbiotic organisms in their guts that are capable of hydrolyzing cellulose.

Answer 3

A little off the subject, when I attended Kent State University in Kent Ohio, one college student went trick-or-treating as a 6 ft. turd embellished with remnants of "sweetcorn?"

Sounds sick and it was but it was actually constructed very well and won the most unique costume. This turd walked up and down the sidewalks of Kent Ohio trick-or-treating. It was hilarious if you could see it--something you'd hopefully never see twice in your lifetime.
