Fermented feed?
One of the biggest misunderstandings in pig feeding is assuming that pigs “do not ferment feed” simply because they are monogastric animals.
Of course, pigs are monogastric.
But that does NOT mean fermentation plays zero role inside pig production systems.
Unlike ruminants that ferment feed extensively before digestion, pigs mainly rely on enzymatic digestion in the stomach and small intestine.
However, certain feed materials especially high-starch ingredients like maize and cassava can still undergo microbial fermentation within the gastrointestinal tract, particularly in the large intestine.
And outside the pig’s body itselfg
fermentation can already begin INSIDE the feed trough when wet feeding management is poor.
Because once uncontrolled fermentation starts
☛ feed acidity changes
☛ odor profile changes
☛ feed intake may reduce
☛ nutrient consistency becomes unstable
☛ performance variation increases
☛ diarrhea risk may rise
You may think: “cassava is cheaper than maize.”
But if
☛ processing is poor
☛ wet feed management is unstable
☛ fermentation becomes uncontrolled
☛ intake drops
then the expected feed cost advantage may disappear biologically.
Think on the feed economics alway.
