Glycerin is a cost effective replacement for high priced corn energy in rations.
In high-starch rations, the energy value of glycerin is equivalent to corn. In haylage-based rations, it
has increased net-energy than corn grain.
Glycerin has been fed as a feed
ingredient to replace energy sources for
up to 10% of the total ration DM for broiler chickens
without negatively affecting feed
intake, weight gain, and feed conversion ratio and up
to 15% of the total ration DM for Holstein dairy cows
without deleterious effects on milk
production or composition.
