Working to Lessen Odors from High Plains Hog Farms. (EH Update)

Article excerpt

Researchers in the Texas Tech University (TTU) College of Agricultural Sciences and Natural Resources are developing a way to eliminate the stink associated with the hog industry. They are raising pigs in what is called the "Sustainable Pork" production system, which rears the pigs under conditions that are more friendly to the environment, the community, the workers, and the animals.

TTU researchers are raising pigs outdoors. Unlike conventional American pig farms, which usually comprise large indoor buildings that house the animals, waste lagoons, poor air quality, and polluting runoff, the Sustainable Pork system works as an environmentally friendly cyclical system. According to John McGlone, director of the TTU Pork Industry Institute, "A properly run outdoor unit will have animal populations that are low enough to allow growth of native or planted vegetation. When vegetation can grow during operations, the site will not have an offensive odor or a runoff of manure."

The acreage is divided into sections, called "radials." The radial design makes sow movement and farm worker efforts more efficient. …
