Biodiesel Byproduct Could be Used in Livestock Feed
The main byproduct of biodiesel production might prove an economical ingredient in livestock feed. Glycerol is separated from oil through a chemical reaction during biodiesel production. The oils without the glycerol become the biodiesel. The glycerol removed could be used as an ingredient in cattle feed. The High Plains Journal has reported that studies by Texas AgriLife Research and West Texas A&M University personnel have evaluated the energy value of the glycerin in replacing corn or hay in cattle diets. AgriLife Research Beef Cattle Nutritionist Dr. Jim MacDonald is comfortable with using crude glycerin up to 7.5-percent of a diet. He adds that no negative impacts were observed on animal health up to 10-percent inclusion in diets of newly received calves. The National Biodiesel Board notes capturing the value of byproducts is becoming increasingly important as production volumes rise.
