How to Build a Farrowing Crate for a Hog

By Angela Libal

Farrowing crates allow newborn piglets to nurse freely while reducing the danger of the mother sow crushing them. Unlike farrowing pens, crates completely restrict the sow's movement to standing up and lying down. They are only for use from birth through a maximum piglet age of 4 weeks, when the piglets are either weaned and the sow returned to group housing or, for free-range pigs, when babies and mother are turned out to pasture. There are many designs and options for farrowing crates. The directions presented here are for the simplest design to build.

Sow Area Side Panels

Farrowing crates are only used for the first 4 weeks.

Weld two of the 7/8 inch, 7 foot long solid shafts approximately 12 inches apart to the top of each rounded end frame.

Mother sows may weigh up to a thousand pounds.

Weld one solid shaft to each end frame 17 inches from the ground on both longitudinal sides of the frame.

Confinement needs change during the lifecycle of the breeding pig.

Attach a bowed floating bar to each of the bottom longitudinal bars. Attach them so that the floating bar extends into the crate when the sow is standing and slowly bows outward as she lies down. The floating bar allows the piglets to get out of the way as she lies down and allows them access to her nipples for nursing.

Doors and Floors

Affix the stainless steel door panels to each end frame with the hinges.

Place one hinge at the top and one at the bottom for a side-swinging door or one at the left and one at the right for a bottom-swinging door. Side-swinging doors allow easier access.

Affix the latch devices to the side of each door opposite the hinges.

Affix the bases of the end tubing to the flooring, allowing 18 inches on either side of the sow crate frame. The method you use to attach the frame to the floor depends on the type of hog flooring you have selected, and the strength of the materials versus the strength of the sow. Typically, you will foot and bolt the end frames into the flooring.

Weld an 18-inch steel panel to each side of each end frame opposite the door panels.

Weld the 7-foot steel panels to an 18-inch steel panel on each side. This completes the piglet portion of the farrowing crate.

Affix a supplemental heat source above each piglet creep area (the 18-inch wide pen areas to either side of the sow crate). Ensure that the heat source is high enough from the floor that the piglets cannot come into contact with it.
