We just started managing a farm with 4 hogs (3 mature sows and a boar). We're looking to help our farm owner make some money off his hogs. He gets fresh produce from a local grocery store when its past its shelf date (still in great shape though). He also has us feeding Nutrena Sow Chow, 16% protein. Any idea about how much feed (if any) this could replace? It is a wide variety of fruits and vegetables, mainly greens though.

Thanks for any help you can provide! :)
