What is the name of pig food?

There isn't one specific name for pig food. It depends on the type of food:

* Commercial pig feed: This is the most common type and comes in various forms like pellets, mash, and crumbles. Brands like Purina, Cargill, and ADM are popular.

* Home-made pig feed: This can be a mix of grains (corn, barley, oats), legumes (soybeans, peas), and other ingredients like alfalfa meal and minerals.

* Forage: Pigs also eat grass, hay, and other green forage.

* Swill: This is a term for leftover food scraps from kitchens and restaurants, but it's not recommended as a primary food source.

So, the best way to describe pig food is by specifying the type you're interested in, for example: "commercial pig feed," "home-made pig feed," or "forage."
