Because livestock can move around in a trailer, causing unsafe handling, false bulkheads can keep the livestock bunched together and potentially prevent unnecessary movement and loss of control in your tractor or trailer.

False bulkheads are very useful for transporting livestock cargo. The bulkheads can separate the livestock's feces and urine from the inanimate cargo you are also carrying.

False bulkheads can help muffle the sound of livestock, helping you be more aware of more important road noises around you.

There is no reason to use bulkheads. It's actually quite dangerous for the animals.
