18. The birds were wing-banded and hung on the slaughter line. They were then subjected to a 7-s stun at 10 to 12 mA and 12 V in a 4-ft stunning cabinet [19]. Approximately 10 s after being stunned, a deep manual throat cut was made to sever the carotid artery and jugular vein with a 120-s bleeding time. Carcasses were scalded at 128°F in an inline scalder [20], defeathered in an inline picker [21] for 70 s, and rinsed for 10 s in an inside-outside online rinse cabinet. The carcasses were removed from the slaughter line by passing through an automatic hock cutter [22], and necks were severed by pneumatic cutters. The carcasses were then rehung on the evisceration line and proceeded through an automated vent cutler and opening machine [23]. and viscera were drawn from the carcass by automated evisceration [24]. The viscera were then manually removed from the carcass.

27. Data were subjected to the analysis of variance using the GLM procedure of SAS software [28]. Pen means served as the experimental unit. Mortality data were transformed to √n + 1 before analysis; data are presented as natural numbers. Significant differences among or between treatments were separated by repeated t-tests using the least square means option of SAS.
