The Principles Of Low Stress
Restraint For Sheep
- Solid sides or barriers around the sheep to prevent them from
people deep inside their flight zones. This is especially important for
wild or excitable animals.

- Provide non-slip flooring for all species of animals.
- 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.
