Milking goats?

What happens to goats when they've finished their milking life? Some goat farms have about 5000 goats on them for milking for cheese, yoghurt, er and milk. What happens to the goat when they've finished with it? I know we eat cows etc, but we don't eat goat meat in England so where does it go? You don't even get goat flavour dog food. I'm puzzled!
