An alternative for animal feed, algae as sustainable protein

Cornell animal science professor Xingen Lei is testing algae as a new protein-rich source of feed to supplement and replace some of the corn and soybean meal mix traditionally given to food-producing animals. By doing so, he could transform a biofuel byproduct into a valuable commodity, potentially freeing thousands of hectares of cropland. "Current animal feed directly competes against human food sources and, thus, is unsustainable," Lei said. "We must develop alternatives to soybean and corn for animal feeds". Read more ...
