Brain signals have shown that calves do appear to feel pain when slaughtered according to Jewish and Muslim religious law, strengthening the case for adapting the practices to make them more humane.
"I think our work is the best evidence yet that it's painful," says Craig Johnson, who led the study at Massey University in Palmerston North, New Zealand.
Johnson summarised his results last week in London when receiving an award from the UK Humane Slaughter Association. His team also showed that if the animal is concussed through stunning, signals corresponding to pain disappear.
The findings increase pressure on religious groups that practice slaughter without stunning to reconsider. "It provides further evidence, if it was needed, that slaughtering an animal without stunning it first is painful," says Christopher Wathes of the UK Farm Animal Welfare Council, which has long argued for the practice to end.
