Effect of slaughter method on bleeding efficiency in chickens

The effect of inducing a cardiac arrest, at stunning, on the weight of blood collected at slaughter was examined in broiler chickens when using seven different neck cutting methods. Cardiac arrest resulted in a slower initial rate of bleeding for each neck cutting method, but by 2.25 min after neck cutting there was no effect on the amount of blood collected. The cardiac arrest treatments were associated with a higher incidence of haemorrhaging in the wings.
