The farrowing crate debate involves genuine welfare tensions between sow behavioral restriction and piglet crushing prevention, with alternative systems increasingly demonstrating both can be addressed.
Individual farrowing crate confinement causes substantial, chronic sow suffering through behavioral restriction over 3-5 weeks per lactation, repeated each reproductive cycle. The justification is piglet crushing prevention - a genuine welfare concern. Alternative farrowing systems that allow sow movement while reducing crushing rates demonstrate that this trade-off is not fixed by biology but by management and system investment. The welfare-optimal path is developing and adopting systems that protect both sow and piglet welfare.
