No, not being too stressed before being killed's fine. 
If they could make the pigs sleepy so there wasn't any potential stress caused by the gas, even better.
Rhiannon, if people are going to eat meat ( which they are) isn't it better to improve the slaughter method?
Being a vegetarian by conscience is a personal choice.
Funnily enough, I respect that.
But I also respect people's desire to eat meat as part of a balanced diet.
I'd much rather the animal welfare groups concentrated on improving the process of slaughter, rather than trying to insist we all make the same choice.
Anyway we are drifting again
