I am starting to look into local GF beef as well. Here is the pricing I got from one farm:
Our beef is all grass fed and finished with no use of hormones or antibiotics. A quarter beef averages 150 lbs of hanging weight at $3.50/lb. Of course Mother Nature doesn't measure out cows according to our measurements, so that can vary considerably depending on the individual animal. All our beef is sold by hanging weight in accordance with GA law, but that can be a bit confusing if you've never bought beef this way. From the above mentioned animal, you can expect about 75lbs of cut, wrapped, labeled and frozen beef which will have cost you no more than $7/lb.
You can expect to receive the following in a standard share of beef.
30 to 40% ground beef (one and two pound packages)
1/4 of all the roasts we cut (averaging 3lbs each)
1/4 of all rib and New York strip steaks (averaging 1 inch thick)
1/4 of all filet (averaging 1.5 inches thick)
1/4 of all sirloin
1/4 of all round steak
1/4 of all cubed steak
organs and bones are optionally available if you request them at the time you reserve your share
Here's another source, from MDA user adrianag:
I have attached 3 price sheets for you to review for the beef. We sell by the cut and the cow. The whole cow is $5.00 a lb, half is $6.00 and a quarter cow is $7.00 a lb.
