The Principles Of Low Stress Restraint
- Solid sides or barriers around the cattle to prevent them from
people deep inside their flight zones. This is especially important for
wild or excitable cattle.
Cattle restraining squeeze chute with angled rubber louvres on the
side which prevent the cattle from seeing people. The side can be
opened for easy access for injections and other veterinary procedures.
The louvres block the animal's vision the same way that louvred shutters
block vision through windows in a house.
- To prevent lunging at the headgate, the bovine's view of an escape
pathway must be blocked until it is fully restrained.
- Provide non-slip flooring for all species of animals.
A good example of a non-slick surface for livestock.
- Slow steady motion of a restraint device is calming, while sudden
jerky motion excite.
- Use the concept of optimal pressure. Sufficient pressure must be
applied to provide the feeling of restraint, but excessive pressure that
causes pain or discomfort must be avoided.
- The entrance of the restraint device must be well lighted, however,
lamps must not glare into the eyes of approaching animals. All species
must be able to see a place to go.
- Livestock will remain calmer if they can see other animals within
- Engineer equipment to minimize noise. High pitched noise is more
disturbing to livestock than a low pitched rumble.
- Restraint devices must be designed to avoid uncomfortable pressure
points on the animal's body.
- Restrain livestock in an upright position.
