Prior to slaughter, most farmed birds move through a constant-voltage, multiple-bird, electrical water-bath stun system. Using this system subjects live birds to stressful and painful shackling, and the potential exists for them to receive prestun electric shocks and induction of seizures while still conscious. The existing electrical water-bath stunner settings, particularly those used in U.S. slaughter plants, are not necessarily based on sound scientific data that they produce a consistent… 

Optimization of Stunning Electrical Parameters to Improve Animal Welfare in a Poultry Slaughterhouse

A frequency of 750 Hz and an average current intensity of 200 mA for each bird in the water bath resulted as the best combination of electrical parameters to obtain a proper stunning without any consequence on the meat quality.

Water-bath stunning process in broiler chickens: Effects of voltage and intensity

The effect of electrical parameters (intensity and voltage) to obtain an effective water-bath stunning in a commercial poultry slaughterhouse was studied. A total of 390 broilers were randomly

The Effects of Different Waveforms and Frequency Values in Pre-slaughter Stunning by Electricity on Some Welfare Parameters and Carcass Defects

Objective: In this study, the effects of electric current application including different wave types and frequency values on welfare parameters and carcass defects to render broilers unconscious

Head-Only Stunning of Turkeys Part 1: The Minimum Voltage Necessary to Break Down the Inherent High Resistance

A method is described to assess the minimum voltage needed at which the impedance no longer decreases, that is likely to produce an effective stun and that is also safe for the operator to use.

The Influence of Broilers’ Body Weight on the Efficiency of Electrical Stunning and Meat Quality under Field Conditions

Evaluating the efficiency of two commercially available types of electrical equipment applied to broilers with different live body weights and the influence of the tested parameters on meat quality highlighted the effectiveness of both stunning systems that apply the best combination of electrical parameters, taking into account the weight of the animal and ensuring its welfare.

Slaughter of animals: poultry

Outcome tables linking hazards, welfare consequences, animal‐based measures, origins, and preventive and corrective measures were developed for each process, and Mitigation measures to minimise welfare consequences were proposed.

Recent Welfare Developments in Pre-slaughter Stunning Techniques for Broiler Chickens

The humane slaughter of production animals is a recurring issue for animal welfare (Shields & Raj, 2010). In today’s poultry industry, broiler chickens are shackled while conscious and electrically

Developing control points for halal slaughtering of poultry.

The current study proposes 6 control points (CP) for halal poultry meat production based on the most commonly used halal production systems to be presented as a starting point for any individual halal certifying body to improve its practices.

Killing for purposes other than slaughter: poultry

Outcome tables linking hazards, welfare consequences, animal‐based measures, origins, preventive and corrective measures were developed for each process and Mitigation measures to minimise welfare consequences were also proposed.



Development of a Constant Current Water Bath Stunner for Poultry Processing

Abstract Problems with conventional water bath stunners have been identified through observation in commercial processing plants and experiment in the laboratory. Due to differences in the electrical

Humane slaughter of poultry: The case against the use of electrical stunning devices

Is the use of electrical stunners adequately discharging our moral obligations with respect to the humane slaughter of poultry? Below, three separate lines of investigation show that we cannot give

Flow routes of electric currents in domestic hens during pre‐slaughter stunning

It was found that the proportion of current reaching the brain varied from bird to bird whereas, with the exception of a slight variation in the proportion reaching the heart, that flowing through the other tissues located in the thorax was similar in all the birds tested.

Constant Current Stunning Effects on Bird Welfare and Carcass Quality

High frequency waveforms were associated with a significant reduction in the incidence of breast muscle hemorrhaging, which indicates that their use could have a considerable commercial advantage.

A comparison of high current and low voltage electrical stunning systems on broiler breast rigor development and meat quality.

High current stunning reduced initial blood loss and delayed early rigor development compared to the LV treatment, but appeared to have little effect on final meat quality.

Tissue resistivities and current pathways and their importance in pre-slaughter stunning of chickens.

Variation in skull bone resistivity may explain why some birds are inadequately stunned, since in these individuals the current density in the brain is likely to be insufficient to induce an adequate epileptic seizure.

The effects of captive bolt and electrical stunning, and restraining methods on broiler meat quality.

Captive bolt stunning using air pressure has benefits over electrical stunning; however, a suitable stunning and restraining device remains to be developed.

Examining techniques for humane culling: chickens' aversion to various gases.

All gases were aversive to some degree, which is to be expected since, at the levels used here, they impair biological functions, however there is scope for using gases, preferably inert gas mixtures (such as argon + CO2), for humane culling.
