Use only with tie-stall systems where walking and observation of cattle is not practical, and where cattle are tied in and used to the stalls that they are in.
Method:
1. Encourage all cattle to be assessed to stand. All cattle must be standing for at least 3 minutes before their assessment begins (allows for urination/defecation).
2. Observe the animal for lameness. Do not score if the animal urinates or defecates during the assessment. The assessment consists of two parts:
a) Assessment of foot placement – Standing Pose
- Observe the foot position and leg placement of the animal for a full 10 seconds in each of the following three positions:
- Behind (about 2 to 3 feet behind the stall)
- Left side (side-view of both legs)
- Right side
- Record the presence of standing on the:
- EDGE,
- WEIGHT SHIFT, and
- UNEVEN WEIGHT (REST) indicators for each position (see Table 1)
b) Shifting of the animal from side to side
- Stand behind the animal with a view of both front and hind feet.
- Shift the animal from side to side, by walking from one side to the other behind the animal and then back; or by tapping her hipbone with your hand to encourage her to move over.
- Observe if the UNEVEN MOVEMENT indicator is present (see Table 1). Observe the foot position and placement, and if the EDGE, WEIGHT SHIFT and UNEVEN WEIGHT (REST) indicators are present after movement.
3. An animal will be scored as requires corrective action (obviously/severely lame) if 2 or more indicators are recorded. Record either ‘A’ for acceptable or ‘R’ for requires corrective action.
