n.a device consisting of
parallel bars set horizontally across a shallow ditch or
depression to
prevent cattle or horses from straying into or out of an
area. The
bars of a cattle guard are spaced far enough apart so as to deter hoofed animals from crossing it, while still allowing for the passage of pedestrians, cars or other vehicles. The guard is often used instead of a gate at the
point where a road passes through a
fence or at a railroad crossing so that cattle do not stray onto the tracks.
