Effect of different electrical stunning procedures on the percentage of broilers with corneal reflex and the occurrence of gross lesions on carcasses.
| Frequency (Hz) | Voltage (V) | Average live weight (kg) | Total current (A) | Estimated current/bird (mA) | Percentage of animals with corneal reflex (%) and standard error (%) | Number of carcasses with gross lesions |

| 200 | 80 | 3.75 | 0.21 | 53 | 25 (4.33) | 29 carcasses with petechiae and blood effusions on breasts and legs |
| 200 | 100 | 3.75 | 0.26 | 66 | 5 (2.18) | 67 carcasses with petechiae and blood effusions on breasts and legs |
| 600 | 160 | 4.2 | 0.60 | 150 | 46 (4.98) | - |
| 750 | 220 | 4.2 | 0.80 | 200 | 12 (3.25) | - |
