Title: Reclining surface in piglet-farrowing unit - has raised projections above base, preventing sow from smothering piglets
Inventor: TUECHSEN HARRI
IPC: A01K1/015
Filed: 1974-03-28
Abstract: The raised projections are spaced apart from each other over the base surface, and may be fixed by means of attachments to the surface, or moulded, e.g. from a plastic sheet in one piece with the base. The raised projections are sufficiently near each other to provide an adequate support for the sow, and also for the piglets to have room to lie between them. The raised projections are high enough for any piglet underneath the sow not to be crushed by her, and high enough for the sow's teats not to come into contact with the floor. This prevents the teats from becoming dirty, and enables them to hang freely for all the piglets in the farrow.
