Nothing would stop me eating decent British-bred and reared meat from my local butcher, and certainly not some of the laughable assertions made on this thread.
As someone born and bred in the industry and who has spent my professional life within it, I'm comfortable with eating meat as described above. Are slaughter houses nice places? No - but so long as the animals are treated with respect, held in decent lairage facilities until their time comes, and correctly stunned, it's not cruel (which is not something I would say about halal and kosher slaughter).
We breed and rear our own cattle - they spend spring, summer and part of the autumn at grass then the winter in large straw yards with ad lib silage and a daily morning feed of concentrates. There's no abuse or cruelty, the cows and calves stay together until weaning at six-nine months, and they are slaughtered locally - we take them there ourselves and they go straight in, no hanging about. We're not hobby farmers either - we have hundreds of them.
Family members breed and rear sheep under similar circumstances; we have neighbours with free range chickens which have open access to several acres of land throughout the day and proper perch barns at night - again, not hobby farmers, there are thousands of them. Other neighbours rear pigs in large straw yards, hundreds of them.
No matter what the anti-meat brigade say, the majority of meat and dairy in this country is done ethically.. Are there bad apples? Yes, of course there are - and most of them get caught (unlike on the continent)
