Commercial FarmA commercial farm is a farm which is deemed to be a viable farm operation and which normally produces sufficient income to support a farm family. "Commercial farm" should not be confused with "factory farm." Factory farms are those which raise animals in high density for the land. They often use steroids or other medicines to build muscle and often antibiotics are used routinely. While animals on "commercial farms" could graze in fields, those on "factory farms" are often confined to a small area.
