My comment: Many gases are used in Europe for gas stunning, including nitrogen or argonne.

If you have no time, read (4).

---------------------
(1) Well, Americans--and probably Europeans, but I do not know for I have never been there--are genuinely concerned about animal welfare.

I was a graduate student in biology at University of Illinois. Hoping to produce antiserum (containing antibodies) from rabbits, I was troubled by regulations on animal experimentation. I mumbled to an American student, and she disagreed.

(2) There are various ways to die.

For humans, there was notorious "death by a thousand cuts" from China, a term that appears in Western literature.

(3) The West has conducted experiments to see how animals can be slaughtered without stress. For example:

(a) A. Bruce Webster, Is Gas Stunning/Killing Ethical?  Department of Poultry Science, University of Georgia,
http://www.csrees.usda.gov/nea/animals/pdfs/bioethics_webster.pdf
(increasing or decreasing air pressure; increasing, decreasing, or sudden deprivation of, oxygen)

* What is LOP in the slides?

"More particularly, decompression creates a vacuum in the sealed chamber, which forces oxygen out of the birds' lungs, simultaneously crushing both lungs. At the onset of unconsciousness, the birds experience ataxia, i.e., loss of posture (LOP), resulting in the birds being unable to maintain a standing position, and having no neck tension. Upon ataxia, the birds exhibit a tonic seizure, with wings extended and the tips of the wings crossed on the distal extremities. Because the birds have been rendered unconscious (i.e., about 90% or more of the brain wave activity of the bird has ceased) prior to ataxia, the birds are unaware of their impending death and do not suffer during the seizures."

(b) R. Jeff Buhr, Is electrical Stunning Ethical?  USDA, Agricultural Research Service.
http://www.csrees.usda.gov/nea/animals/pdfs/bioethics_buhr.pdf


Both of which appeared in pages 16 and 22 of

Richard Reynnells (ed), Bioethics Symposium: Proactive Approaches to Controversial Welfare and Ethical Concerns in Poultry Science. World Congress Center, Atlanta, Georgia, Jan. 23, 2007.

(4) It is known long ago that the more stressful is the animal before and during the slaughter, the worse the meat tastes. (Have you have wondered why meat in US look and taste better than that from your or my home country (Taiwan)? A lot of work is put into it, to achieve this outcome.)

(5) The goal is that the animals (be they chickens, pigs, cattle) do not know they are going to die, nor get stressed not suffer.
