What is this device?

https://en.m.wikipedia.org/wiki/Captive_bolt_pistol

Usually not fatal by itself nowadays because if you scramble brains you risk spreading mad cow to people. Stuns before you bleed the animal out.

We're civilized people btw
Not fatal D: that’s barbaric
Used to do it with a poleaxe or a mallet. It's considered better than slicing the animals carotid/aortic arch and hanging them upside down before stunning.
There has to be something better than either of those choices D:

I think neutral gas asphyxiation would be. Unfortunately they usually use carbon dioxide instead for pigs. I consider carbon dioxide to be much worse. It's both acidic and makes you very aware you're suffocating. At high concentrations unconsciousness is generally very quick though because your blood will literally dump stored oxygen whenever it encounters high levels of CO2. Makes lungs work in reverse like you were in space.

Edit: I use your here because I'm only trained in human physiology but it works essentially the same

Just curious wdym by lungs working in reverse where CO2 is what’s circulated and oxygen is the exhaled “waste”

That's pretty much it. Your hemoglobin decouples oxygen for CO2 in areas of high CO2 concentration. This is good when you're circulating oxygen to muscles that need it. It's bad when you're dumping all your oxygen reserve to the atmosphere and instead making your blood more acidic.

Coupled with the low partial pressure of oxygen, you'd be going unconscious within seconds. But those seconds are... not pleasant.

This is currently the most efficient method for slaughtering livestock for consumers. It’s efficacy can be measured by the amount of stress hormones released into the meat. The animal doesn’t have time to process the pain of the pneumatic bolt before it is stunned and exsanguinated.

Here is a sciencey article on the subject: www.ncbi.nlm.nih.gov/pmc/articles/PMC7463084/

Effect of stress during slaughter on carcass characteristics and meat quality in tropical beef cattle

This study aimed to determine the effects of stress during slaughter of beef cattle on physiological parameters, carcass, and meat quality at a Federal Inspection Type slaughterhouse located in the southeast of Mexico.A total of 448 carcasses of male ...

I know cows are built like tanks but couldn’t you just suffocate them peacefully with CO2 like the people that kill themselves by sitting in their car on their closed garage?
Absolutely nothing peaceful about it. Pigs in UK are killed with CO2 and it’a harrowing. The only advantage is that slaughterhouse workers don’t need to look their victims in the eyes while it happens. The pigs get lowered into a gaschamber where it happens. They shit themselves and scream their lungs out while fighting for up to 3 minutes of their miserable lives. You can find a pretty recent documentation about it called Pignorant by vegan activists who infiltrated those facilities. They’ve also demonstrated in front of the HQs of those companies (e.g. Pilgrims) by playing back the audio from the gas chambers.
I don’t understand why does it work on humans and not on pigs?

I’m not into that topic. According to a quick search the exhaust fumes method is working because of Carbon Monoxide (CO) and not Carbon Dioxide (CO2). Wasn’t there a redditor who did not recognize he was killing himself with CO and other redditors saved his life?

I’ve also found a pretty repulsive study done on piglets about the ideal gas for euthanization. It found a 2-step procedure with N2O (Nitrous Oxide) + O2 (Oxygen) as an anesthetic for 12 min followed by killing via CO2 was the most stress-free method.

The activists are protesting against the CO2 method in the UK currently. And I hope the management of the respective companies get public hell for it. I don’t know if it’s used in other countries too.

Gas alternatives to carbon dioxide for euthanasia: a piglet perspective - PubMed

The search for alternative methods to euthanize piglets is critical to address public concern that current methods are not optimal. Scientific evidence supports that blunt force trauma is humane when performed correctly, but most people find it visually difficult to accept. The use of CO2 is often r …
