Glycerol improves feed efficiency in cattle

A 150-day study conducted by University of Missiouri-Columbia (UM) Professor Monty Kerley has found that when glycerol is added as 10% of feedlot cattles' rations, it improves the animal's feed-to-weight-gain, or feed efficiency ratio.

Glycerol, a co-product of biodiesel production, has been fed to cattle for years in Europe, Kerley noted.

Because biodiesel production has increased so much over the last few years there is an ample supply of glycerol available. The cost of glycerol has dropped as a result of this increased supply, so this could allow cattle farmers another option to lower costs.
