Q

We discussed 5 fates of nutrients in ruminants. Describe one of the fates, and an example of it.

A

Fate 5 is when the microbes, the lower tract/GI tract, and the colon or cecum do not digest or ferment the ingested feed at all. This would the materials that the microbes can’t digest, so an example would be lignin products.
