TI Poultry stunning and slaughter

QU Seminar on pre-slaughter stunning of food animals, European Conference Group on the Protection of Farm Animals, Brussels, 2 - 3 June 1987

PT Proceedings

AB Conclusion: 1. We are not in a position yet to recommend a current which stuns 99% of birds subjected to water bath stunning. 2. There is a wide range of electrical waveforms used in stunning circuits and this will make it difficult to give a single recommendation. 3. On humanitarian grounds there are advantages in including a cardiac arrest at stunning and in broiler chickens this should be achieved with 148 mA per bird when using a 50 Hz sinusoidal AC. 4. The effects of high stunning currents on carcass quality are not fully understood, and the existing evidence is contradictory. There are four reasons for stunning poultry before slaughter:- 1. Minimise the chance of birds feeling pain during and after neck cutting. 2. Minimise distress that could occur during bleeding out. 3. Immobilize the bird to allow neck cutting to be performed easily and accurately. 4. Prevent the convulsions which occur during bleeding out in unstunned birds.
