To Protect Sows and Piglets Use of High-Tech Camera

To protect newborn piglets, Agricultural Research Service (ARS) scientists and collaborators are using 3-D imaging by monitoring adult female pigs' behavior.

Nearly 15 percent of pre-weaned piglets die each year. According to U.S. pork producers, many are crushed by sows (adult female pigs). Modifying the sows' stalls or crates may help reduce piglet deaths.

According to ARS agricultural engineer Tami Brown-Brandl, the first step is to evaluate sow and piglet behavior in their stalls. Animal behavior contains vital clues about health and well-being that producers can use to better manage their livestock.

Brown-Brandl and a team of scientists from China, Iowa Select Farms and Iowa State University developed a system to automatically process and analyze 3-D images of sows. A camera mounted over birthing crates captures images to determine a sow's behavior and posture: if she's eating, drinking, standing, sitting, or lying down.

The system, which accurately classifies behavior, could potentially help prevent sows from crushing their piglets, according to Brown-Brandl, who works at ARS's Roman L. Hruska U.S. Meat Animal Research Center in Clay Center, Nebraska.

This technology allows swine producers to better monitor their pigs and determine whether management adjustments, such as changes in crate size or pen arrangement, are needed, Brown-Brandl adds. The data could also help producers locate sick animals more quickly.
