The Principles Of Low Stress
Restraint For Sheep

  1. Solid sides or barriers around the sheep to prevent them from seeing people deep inside their flight zones. This is especially important for wild or excitable animals.

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

  3. Slow steady motion of a restraint device is calming, while sudden jerky motion excite.

  4. 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.

  5. 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.

  6. Livestock will remain calmer if they can see other animals within touching distance.

  7. Engineer equipment to minimize noise. High pitched noise is more disturbing to livestock than a low pitched rumble.

  8. Restraint devices must be designed to avoid uncomfortable pressure points on the animal's body.

  9. Restrain livestock in an upright position.
