Livestock in the lab of Cornell animal science professor Xingen Lei have been feasting on an unlikely diet for landlocked Ithaca: marine algae. Dried defatted algae is a byproduct of a biofuels project led by Chuck Greene, professor of earth and atmospheric sciences, and Jeff Tester ’66, MS ’67, professor of chemical and biomolecular engineering, and it can replace up to one-third of the soybean meal in pig and chicken diets. With its high lipid and protein content, algae feed not only replaces a portion of traditional feed, it transforms a biofuel byproduct into a valuable commodity and frees up valuable acreage for the production of human food.
