TI Electrocution, stunning and chicken carcase appearance

QU 6th Australasian Stock Feed Cent. 1975

PT Manuskript

AB One hundred broilers were tagged and placed on a commercial processing line. Fifty were electrocuted while the others were stunned prior to exsanguination and processing. Four observers were unable to detect differences in the appearance of either group of fresh carcases. Trials were also undertaken in which groups of chicken were either stunned and bled-out, electrocuted, electrocuted and bled-out, decapitated, or Halal-killed prior to scalding, plucking and evisceration. Edible portions of the carcases which comprised the soft tissues and meat were minced. Samples of the mincemeat from each group were analysed and the mean haemoglobin concentration was 0.19, 0.36, 0.22, 0.17 and 0.17 mg Hb/g of soft tissue respectively. There was no significant difference in the blood content of carcases that were electrocuted and bled-out compared to the blood content of carcases prepared from broilers that were stunned and bled-out. This supported earlier observations that it was not possible to tell the difference in appearance between carcases prepared from electrocuted chickens and carcases of stunned chickens. Furthermore, electrocution ensures that broiler chickens are humanely slaughtered.
