Just to give you a little idea of what we got back from our butcher.
We sent 2 GOS recently with a live weight of 405lb between them

[size=78%] When we collected them we weighed all the meat, not including liver, kidney etc and got, what I think to be a good return.[/size]
We had all the meat packaged as to what we wanted so could just put it straight in the freezer;
Chops - 28lb
Sausage - 18lb
Belly meat - 10lb
Joints - 146lb
Rib - 18lb
We also had a lot of extra bits, offal etc for the dogs so we were well pleased with the butcher. They also asked what size joints we wanted!!!!! Very pleased
