متن کاملA Review of Different Stunning Methods for Poultry-Animal Welfare Aspects (Stunning Methods for Poultry).
Electrical water bath stunning is the most commonly used method for poultry stunning prior to slaughter, but has been questioned on animal welfare and product quality grounds. Controlled atmosphere stunning (CAS) methods, involving a variety of gas mixtures, have become increasingly common, at least in Europe. CAS methods have been perceived as an improvement from an animal welfare perspective,...
متن کاملWelfare during stunning and slaughter of poultry.
This paper describes research on the electrical stunning of poultry and the problems of achieving an effective humane stun with water bath stunners. The welfare and meat quality advantages of using gas mixtures to stun and kill birds are then described. The evidence strongly suggests that chickens and turkeys can be killed very humanely using either 90% argon in air or a mixture of 30% carbon d...
متن کاملThe effects of electrical and controlled atmosphere stunning methods on meat and liver quality of geese.
The objective of this research was to investigate the effects of electrical and gas stunning on the meat and liver quality characteristics of liver geese. Sixty birds were slaughtered at 12 wk of age, in groups of 20 at three different times. Thirty birds each were subjected to one of the two stunning methods. Deboned breast fillets and thigh muscles were evaluated for hemorrhaging, amount of b...
متن کاملRemote monitoring of electroencephalogram, electrocardiogram, and behavior during controlled atmosphere stunning in broilers: implications for welfare.
This study examined the welfare implications of euthanizing broilers with 3 gas mixtures relevant to the commercial application of controlled atmosphere stunning (CAS). Birds were implanted/equipped with electrodes to measure brain activity (electroencephalogram, EEG) and heart rate. These signals were recorded using a purpose-built telemetry-logging system, small enough to be worn by each bird...
