Glycerol is a viscous, colorless and odorless liquid that, thanks to its energy content and its high water solubility index, is widely used in the food, pharmaceutical and cosmetic industries. It is the main co-product obtained during biodiesel production and represents a valuable source of energy for livestock.
Glycerol ferments rapidly in rumen and increases the butyrate/propionate ratio in the ruminal fluid. Butyrate is known to stimulate the development of the rumen epithelium so glycerol can be a sought-after ingredient for calves’ diets during weaning. In addition, due to its sweet taste, it can improve feed palatability.
