The initial stages of processing poultry usually involve electrically stunning birds, severing neck blood vessels and allowing a specified time interval for bleed-out. A major goal of processing plants during this period is to optimize blood release. The objective of three experiments was to evaluate two types of stunners (a plate stunner and a brine stunner) and two types of circuits [alternating, (A.C. at 60 Hz)] current and direct current (D.C.) to determine which was best for maximizing bleed-out in broilers. The first experiment demonstrated that a plate stunner was not effective in stunning broilers when connected to an A.C. or D.C. circuit in that contact between the bird and steel plate was inconsistent from one broiler to the next. Employing a brine stunner the voltage setting for maximizing bleed-out in an A.C. and D.C. circuit was 50v. (effective (eff.)) and 90v. respectively. When the optimum setting of the A.C. circuit was directly compared with that of the D.C. circuit the A.C. setting of 50v. was found superior. It is recommended that an A.C. circuit at 60 Hz connected to a brine stunner at a setting of 50v. be employed to maximize bleed-out in broilers. |
