How to Yield Grade Beef

Yield Grading �While Quality grade deals with a prediction of the eating quality of the meat, Yield grade is a measurement of the amount of edible meat the carcass will produce. �USDA Yield grades for beef are as follows.

• Yield Grade 1 = Over 52. 3% • Yield Grade 2 = 50 -52. 3% • Yield Grade 3 = 47. 7 -50. 0 %

• Yield Grade 4 = 45. 4 – 47. 7% • Yield Grade 5 = Less than 45. 4 %

Calculating Yield Grade �Yield Grade is determined by, • Thickness of Fat over the Ribeye at the 12 th rib. • Area of Ribeye • KPH % (kidney, pelvic, heart fat)

Yield Grade Formula �To calculate yield grade use the following formula. • 2. 5 + (2. 5 X 12 th Rib Fat) • + (. 2 X KPH ) • + (. 0038 X HCW) • - (. 32 X REA) = Yield Grade

Yield Grade Example � Beef 1 • Carcass weight • 12 th Rib Fat • KPH Fat • Rib Eye Area 735. 4 2. 5 12 � Beef 1 • 2. 5 + (2. 5 X. 4) = 3. 5 • +(. 2 X 2. 5) = 0. 5 • +(. 0038 X 735) = 2. 79 • - (. 32 X 12) = 3. 84 � 3. 5 + � Yield 0. 5 + 2. 79 – 3. 84 = 2. 95 Grade = 2 (low) Yield Grade Formula 2. 5 + (2. 5 X 12 th Rib Fat) + (. 2 X KPH ) + (. 0038 X HCW) - (. 32 X REA) = Yield Grade

Yield Grading Table High, Average & Low are divided up into thirds. High = 0 -. 33, Average=. 34 -. 66, Low =. 67 + � Remember that the higher the number the lower the yield grade. (2. 95 = Yield Grade 2 Low) � Scoring is 10 pts for the correct answer, 8 pts for placings one on either side and 5 points for two on either side. � Carcass Number YG 1 H 1 2 3 4 5 A YG 2 L YG 3 H A L H A 5 8 X 8 5 YG 4 L H A YG 5 L H A L
