The use of fermented wet feed for pigs has increased world-wide during the last decade, incorporating a variety of fermentation techniques and feedstuffs.  Fermented feed is produced by the incubation of solid material (ie, cereals and grains) together with a liquid phase (ie, whey or wet distillers' grains).

 

Whey and wet distillers' grain may contain high numbers of micro-organisms that can also positively simulate the development of a beneficial microbial population in feed. The fermented wet feed reduces the pH and the number of coliform bacteria in the animal gastrointestinal tract.
