A sow farrowing station to reduce the mortality of piglets includes a slab, a surrounding crate to constrain the sow, the slab defining within a crate a floor transport region consisting of independent pressure sensitive members which travel over the region to transport piglets from beneath the sow but when the, sow itself steps onto one of the pressure sensitive transport members, that member stops its travel so that the sow does not have to continually "walk" yet when, the sow lays down all the transport members are arrested and the piglets can then move to nurse from the sow.

Why it's free to use
- Filed April 18, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 18, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 18, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
