current shock, not strong enough to kill a human or a large animal such as a cow or sheep from short-term exposure, but strong enough to cause significant pain.
The electric cattle prod is designed to inflict a painful shock to cattle, and thus "prod" them along; the pain stimulates movement.
There are various designs of electric cattle prods. Their shape is designed to make them easy to use and handle. They range in length from six inches (usually of a more encased rectangular
prism design like a
stun gun), to up to six feet. Most are simple designs powered by 9-volt battery or similarly small batteries, to make them small and light enough to wield. One typical design is a box containing a large battery (or battery pack) at the handle end and wires embedded in a fibreglass rod, ending with two electrodes in a rubber tip.
As the precursor of stun guns, cattle prods have a wide range of voltage with enough current to operate in the same manner as a stun gun does against humans.
The use of electric cattle prods has been debated by many people. Organizations such as
PETA contend that the use of cattle prods is as much mentally harmful as it is physically. Most farmers contend that the short shock is minutely felt, and soon forgotten.

Usage on people in policing and torture

Cattle prods today are designed with a high range of voltages and currents. If more powerful prods are applied continuously to the skin, the current eventually causes heating,
searing, burning, and scarring of skin at the contact point. Electric prods have found favour with torturers.
Prior to the development of
stun batons and the
taser, electric cattle prods were also used on people in varying degrees. Their first common usage on people occurred during the
Civil Rights Movement of the 1960s; prods were first adopted by police officers in

. It works at very high voltage and low current so as to maximize pain and minimize the physical marks left on the victim. Among its advantages over other torture devices is that it is portable, easy to use, and allows the torturer to localize the electric shocks to the most sensitive places on the body, where they cause intense pain that can be repeated many times.

Alternatives
Cattle can be difficult to move and direct for a variety of reasons. Prods can be useful for moving stubborn or aggressive animals,
but often cattle will not move forward when they are fearful of something they see, hear, or smell. Removal of these distractions or hiding them, such as with solid wall partitions, can greatly reduce animal-handling problems; however, cattle handlers cannot completely overcome the animal's decision not to move forward.
By studying the psychology of the animals and redesigning the working environment it is possible to handle the animals without the need for brute force and causing pain and suffering to the animal in many, but not all, cases. Significant work in this regard has been done by
