Abstract Crushing of piglets by sows in farrowing pens was studied in a 2×2 experiment to evaluate the effect of different pen design features. Pens had either concrete or plastic-coated expanded metal flooring, and half of the pens were fitted with a horizontal bar 23 cm above the floor, bisecting the pen. The bar was intended to prevent the sow from rolling suddenly onto her side, a movement known to crush piglets in open pens. Ninety-eight litters were analyzed during the first 3 days after… Expand
