Using Crude Glycerin in High Forage Diets - A Way to Improve the Profitability of Biodiesel Production

This team estimates that confined beef cattle fed in Texas could consume all the glycerin resulting from 3 billion gallons of biodiesel production capacity if it were included at 10% of the diet. This allows for the development of a market that could grow six times the current level of biodiesel production. While most preliminary research has focused on replacing corn with crude glycerin, this project investigates replacing forage with crude glycerin. Replacement of forage is logical for three reasons: First, in vitro digestibility data suggests that the volatile fatty acid profile resulting from glycerin fermentation more closely matches the fermentation of forage than corn. Secondly, forage is difficult to manage for many confined animal feeding operations, so replacing forage with glycerin would be pragmatically beneficial to beef cattle producers. Finally, potential development and growth in cellulosic ethanol production may displace forage sources previously used for livestock production thereby increasing the cost of forage in beef cattle diets.
