There's a misconception out there that we're going to make stalls disappear completely. That's not true. During the farrowing process, when they're having the piglets, and the piglets are very susceptible to having a very large mother lie on them, there's no jurisdiction saying that this is really a threat, because having a big mother lying on a very small pig is not really good animal welfare for the baby pig.
We think there's enough evidence that we can make the change to partial group housing for gestation from our current state of having total gestation stalls. If we do it right, we can do it with minimal loss in productivity.
