Live weight is the weight of the live animal. Generally for a lamb that would be between 85 and 100 lbs. Hanging weight, sometimes called "hot hanging weight" is about 60 percent of this, because there is now no skin or internal organs, except perhaps the liver and kidneys if the customer want them. You would now be down to 60 lbs assuming a 100 lb live lamb. The butchered weight or market weight is about 60 percent of this, as the butcher trims off fat, some bones etc. You now have only 40 lbs of meat for a 100 lb live weight animal. The butcher or abattoir also charges at least $50 for the processing and packing. To do some more math, the 100 lb lamb, purchased at say $1.50 per pound plus butchering etc. becomes $200 and this is for 40 lbs of meat. Therefore price per pound to the customer is $5 per pound.
You will also have to have a separate freezer to keep your meat in that is for sale to the public. This is the law in Ontario.
You have the additional problem of dealing with the sometimes dissatisfied public, advertising costs, and running back and forth to the abattoir. Some people get around this by making the customer deal directly with the abattoir and paying their costs. If the butcher makes a mistake in the cutting, then they can complain to him!
Personally, I find it a lot easier to sell the lambs live at auction. You can take in as many as you like at one time and you will probably get almost the same amount of money at the end of the day.
