Yes, if I remember correctly that is about what the yield would be.
We would have to do 'cutting tests' on everything... I MEAN EVERYTHING Start out with the whole product; if in a bag, record the difference in bag wt and net wt, the balance being purge. Process the piece, cutting, boning, slicing, separating, etc. to finished cuts. Weigh each cut or qty and compute the percentage of the cut to the whole. You would have x lbs/oz of skin, of bone, of fat, of breast meat, of drumstick meat, of thigh meat, of neck, etc., total up the weights, subtract from the original whole weight, difference is the cutting loss (juices, etc. left on the table, bis and pieces being dropped on the floor, etc.).
Take each weight and convert to ounces. Take total net weight and convert to ounces. Divide each portion weight by it's whole to get the % of yield of each, all parts and pieces totalling to 100%. Then you can figure the % of total waste to meat, etc.
You compile your cutting tests and average them out on like tests, so if you have 27 tests done on a certain way of cutting an animal the same exact way each time, you can come up with Average Mean %/Total and hold that as a given factor. Now, if the bird costs you $A, and you sell it whole for $B, you realize a certain % of profit. But, if you cut it up what price do you have to get on each part and piece to realize the same or higher profit? Just plug numbers in, multiply out by ave. weights and get a pricing profile. Because, based on your cutting tests, a whole case of birds (ave. 27/cs) will yield you x amt of lbs. of breast meat, thigh meat, and so on and you can set different pricing profiles and compute your overall gross profit yield for the case.
Meatcutting and Math go hand in hand!
