I came on here to down stress after collecting piggies from abattoir this afternoon. I always panic in case anything has gone wrong, especially when the freezer is as empty as it is now.
To answer your question it should not be stressful nor full of paperwork. We are in France I think though the rules are all the same.
We take the two pigs in a metal livestock trailer. Just before they go we slap them with our holding number. This worries me far more than it worries them. This is a dangerous exercise whereupon the rest of the world keeps well away from the pig pen, as I am prone to covering absolutely everything with the tattoo ink.
At the abattoir I unload them into the appropriate pen signified (mostly sign language) by the reception man. I already have the paperwork prepared, this shows my name, address holding number and slap mark number and the number of pigs I am sending. Top copy I keep they have the other 4.
Sometimes I have to sign a form, sometimes not. It depends on how rushed the reception man is. Pigs go off, quite happily. (They wont let me go to the door with them), I wait till they tell me they are done (around 2 minutes).
Five days later I take back top copy - pay - it varies but never more than 28 euros per pig. Sign receipt take receipt to collecton area where a cheerful man always drops them in the boot. I cover them with ice packs and polythene and deliver to butcher.
Two suggestons from mine and others experience:
DO NOT feed them more than a handful of breakfast on slaughter day. If possible reduce the previous nights dinner by at least half.
On collection check the slap number of your pig that it is yours.
Dont worry its easy.
