farrow

This seemed to relate more to the effects of pregnancy confinement, with stalled sows having a greater proportion of stillborn piglets than group housed sows which farrowed in a similar crate system, and producing piglets which took longer to stand and to suckle.

However, the sows kept in an ESF system during pregnancy and farrowed in a group farrowing pen (EG) nursed their litters less often, and initiated fewer successful nursing.
