A new video by Smithfield Foods takes the topic of sow housing back to the drawing board.

In the video recently released by Smithfield on their YouTube channel, viewers can see group housing systems for pregnant sows at company-owned farms.

The video starts out in a classroom with an instructor drawing out on a whiteboard the various housing systems used during the life of a sow, particularly during pregnancy. Sows are shown in real video and also in cartoon images on the whiteboard to help educate consumers about the process of raising pigs.

Smithfield aims to have all sows in group housing by 2017 for U.S. company-owned farms, and worldwide by 2022.
