Effects of current and waveform on the incidence of breast meat haemorrhages in electrically stunned broiler chicken carcases.
The effects of the current and its waveform on the prevalence of broken bones and breast meat haemorrhages in electrically stunned broiler chickens were examined at two poultry processing plants. Increasing the current over the range from 68 to 115 mA per bird had very little effect on the carcase quality, but increased the incidence of broken furculum and coracoid bones in birds stunned with a sinusoidal alternating current (AC). Clipping a sinusoidal AC with a thyristor had a pronounced effect on the carcase quality, and resulted in more broken bones and breast meat haemorrhages.
