Pig Digestive Tract

         The type of digestive tract, briefly describing the key organs and physiological structures  Describe the types of feed ingested and discuss how the digestive system has evolved to efficiently obtain nutrients from the available feeds  If it is a production animal, describe the influences of production systems on the animal. For example grazing animals are restricted to consume only feeds available within the paddock they are enclosed (i.e. they cannot free forage)  Describe any limitations to the digestive system (for example can only digest a specific feed type, limited volume, inefficiency etc.)
