ABSTRACT:
A farrowing house for a sow, a method of fabricating an animal shelter, and a mold for casting a reinforced concrete animal shelter. The house or shelter includes a crib structure defining two sets of spaced rails having at least one set pivotally connected to the end walls. The method of fabricating the animal shelter includes the steps of constructing an inner mold and an outer mold, placing an inner reinforcing cage between the two molds, and pouring a concrete substance between the two molds and around the cage. The mold comprises an inner shell and an outer shell having external stiffening rods to preclude outward buckling.
