Alternative markets: biotech seeks farm animals

Sioux Center, Iowa-A biotech company here is harvesting ingredients from U.S. farm animals to make supplements and medicines, the Associated Press reports.

Allen Kramer, founder of Sioux Pharm, says, "We can use eyeballs from the cow, their brains, their pituitaries, their intestines, their stomach. We can isolate important products from almost every organ of the animal."

The company is one of three in the country using animal cartilage to make chondroitin sulfate in the United States, and uses cow tracheas.
