It is difficult to determine percentages when very small groups of animals are scored. Normally 100 cattle, pigs, or sheep would be scored. A sample size of 100 animals makes it easy to determine accurate percentages. If only 50 animals are scored, a single fall would cause a plant to exceed the 1% limit on falling. The chart shows adjusted scores when an audit is done on less than 100 animals. The adjusted scores will prevent a plant from being penalized because the sample size is too small. In a very small sample of 10 or less animals, insensibility must be 100% and they must get a perfect score on two out of three variables of stunning, falling, and vocalization. They are allowed one non-compliance on either a missed stun, a single fall, or one animal vocalizing. When data in a small plant is pooled, the percentage for 100 animals should be used. The chart below has adjusted scores for single audits done with small samples.
|Number of Animals per Audit||100 Animals||50 Animals (single audit)||25 Animals (single audit)||10 or less Animals (single audit)|
|Captive Bolt Single Shot||95%||96%||96%||*See Text|
|Electrical Stunner Correct Placement||99%||98%||96%||*See Text|
|Dragging Sensible Animals||0%||0%||0%||0%|
