its all down to the area you live in etc etc around here everyone and his dog keep pigs for meat selling 1/2 a pig for £90 - £100 tops one guy i know sells 1/2 a GOS for £55 and thats hard going for him.
the other thing is not everyone wants the hastle of AHO and registration of a food outlet, transporting 1/2 pigs around to customers not easy if you send a litter off all at once.
i know when we were selling whole and half pigs by the time you took your weaners, feed, transporting too and from slaughter transport for delivering and thats without factoring in your time. i can make more money selling weaners & pedigree breeding stock than i can pork, i know this because i keept very careful records and have done so since starting out with pigs along with growth charts of each breed we have kept.
we all have different take on how we want to go which is good imo without wanting to sound offensive mrs s you seem to think everyone wants to do as you do which would not be a good thing to you or others like you as we would all runout of customers.
i dont see selling weaners as a lost opportunity i see selling weaners as a gateway to breed more pedigree registered animals to sell as breeders and show animals much less stress too.
