I'd wonder if it was enough information to create a pig UX for a machine. Starts with flashing a light or making a sound when it hears certain patterns of noises, becomes stimulus response like Pavlov experiments, but adapts to a more sophisticated command language for food, water, flavors, nutrients, etc. Then see if the initial group can teach new pigs to use the grunt language system, or if nursing sows teach their piglets the grunting system. Eventually, there will probably be groups of pigs who use the grunting system to identify each other and align based on learned behaviors, only driven by stimulus response and perhaps without true sapience or consciousness, and it will basically be twitter for pigs.

But more seriously, the idea of using ML to adapt to building complex interfaces for animals driven by more subtle stimulus response is pretty fascinating.
