Glycerol as Feedstuff for Ruminant

Abstract

The increase in bio-ethanol industry has created a need for alternative to corn for ruminants. In the other side there is an increase availability and promote favorable pricing for glycerol, a primary co-product material. Glycerol is used as energy additive in ruminant nutrition. Glycerol in particular, is used for their glycogenic and anti-ketogenic properties. Glycerol is ingested by ruminants with phospholipids in the cell wall or lipids in the seeds and is part of the lipidic fraction of the diet. Glycerol is considered to be rapidly fermented within the rumen thus its low concentration as free glycerol in rumen fluid.
