beef yield grade formula

Yield Grade 5 discount to get $-29.00. The more fat opposite the ribeye, the higher the numerical value of the PYG.2. Final quality grades are arrived at by a composite evaluation of maturity and marbling. However, they also show differences in the total yield of retail cuts. Yield Grade 5 = Less than 45.4 %. Determine the preliminary yield grade (PYG).Measure the amount of external fat opposite the ribeye. Producers tend to use yield grades more than consumers. Yield Grade 2 = 50-52.3%. Yield Grade – Yield Grade is an estimate of percent retail yield of the four primal cuts of beef (chuck, rib, loin, and round) and is also known as cutability. USDA 1 – Most desirable, trim USDA 2 USDA 3 – Industry average USDA 4 Yield Grade is determined by, Thickness of Fat over the Ribeye at the 12th rib. USDA 1 – Most desirable, trim USDA 2 USDA 3 – Industry average USDA 4 The base PYG is 2.00. Yield Grade 3 = 47.7-50.0 % . Instead of thinking simply about yield of finished animals, the team at Certified Angus Beef (CAB) are advising to analyse dressing percentage. Figure 1 Relationship between marbling, maturity, and carcass quality grade. KPH % (kidney, pelvic, heart fat) Yield Grade Formula. The normal range is 950-1500 pounds with an average weight of 1150 pounds. Yield Grade identifies the difference in the yield of lean red meat to waste fat. Yield grade is determined by several factors, which include external fat cover, internal organ fat and degree of muscling, which is measured as ribeye area (in square inches). In beef, yield grades estimate the amount of boneless, closely trimmed retail cuts from the high-value parts of the carcass--the round, loin, rib, and chuck. For example, if the Choice, yield grade 3, 550- to 900-pound carcass price is $105.00/cwt, a Select, yield grade … Yield grades. Yield grade 1 is the leanest and highest in yield or cutability and yield 5 is the fattest and lowest in yield or cutability. Step 1: Assign preliminary yield grade by adjusting for thickness of fat over ribeye. Area of Ribeye. Understanding Yield Grades for Beef and Lamb Beef Yield Grades % of Carcass as Boneless, Closely Trimmed Retail Cuts % of Total Yield From the Round, Retail Cuts Grade Rib, Loin, and Chuck From the Carcass 1 52.4 or greater 79.8 or greater 2 50.1 to 52.3 75.2 to 79.7 3 47.8 to 50.0 70.6 to 75.1 4 45.5 to 47.7 66.0 to 70.5 Marbling has a strong correlation with the juiciness and flavor of beef. Yield grade is determined by several factors, which include external fat cover, internal organ fat and degree of muscling, which is measured as ribeye area (in square inches). GRADING SIMULATION The Grading Simulation allows the viewer to apply his/her knowledge to an interactive grading exercise. 1. Beef Carcass Quality • USDA Quality Grade – Skeletal Maturity – Marbling • USDA Yield Grade – Ribeye Area – %KPH (kidney, heart, & pelvic fat) – HtHo t Carcass WihtWeight – 12th Rib Fat Thickness Yield grades range in score from 1 to 5 and provide only a certain degree of accuracy when estimating cutability, or the amount of saleable beef for a particular carcass. Calculating Beef Yield Grades Worksheet Sample Calculation: Find the beef yield grade for an animal that weighs 400lbs, and has a %KPH of 0.5%. The entire grid is shown in Table 3. Yield Grade 1 = Over 52.3% . These measurements are entered into a formula that calculates the fi nal yield grade. The price received for each carcass is the base price plus the particular premiums and discounts. Calculating Yield Grade. USDA yield grades are calculated using an equation that incorporates adjusted fat thickness, percent of kidney, pelvic, and heart fat, hot carcass weight, and ribeye area. These measurements are used in the official USDA formula as follows: Yield grade = 2.5 + [(2.50 x adjusted fat thickness, inches) + 0.2 percent of kidney, pelvic, and heart + (0.0038 x hot carcass weight, pounds) - (0.32 x area rib eye, square inches)] When computing yield grades, any decimal is dropped; yield grades are presented as whole numbers. These four factors are used by the USDA grader in a formula to determine yield grade. Yield Grade 4 = 45.4 – 47.7%. numerical value of the USDA yield grade, the higher the expected yield of closely trimmed, boneless retail cuts. This measurement should be made at a point three-fourths of the way up the length of the ribeye from the split chine bone. Yield grades range in score from 1 to 5 and provide only a certain degree of accuracy when estimating cutability, or the amount of saleable beef for a particular carcass. The animal’s fat over ribeye is 0.2” and the area of ribeye is 6.6 square inches. Based on this fat thickness, a preliminary yield grade (PYG) can be established. USDA Yield grades for beef are as follows. STAMPING Once a carcass has been evaluated, the USDA grader stamps the carcass with the quality grade and yield grade. The yield grade equation is as follows: Yield Grade = 2.50 + (2.5 x adjusted fat thickness,inches) Yield Grade – Yield Grade is an estimate of percent retail yield of the four primal cuts of beef (chuck, rib, loin, and round) and is also known as cutability. Beef Yield Grades. Beef yield grades are determined on the basis of areas of rib eye muscle; thickness of fat over the rib eye; percent of kidney pelvic and heart fat; and the carcass weight. Economically important traits for beef cattle evaluation discussed below are live weight, dressing percent, muscling, fat thickness, yield grade and quality grade. Yield Grade identifies the difference in the yield of lean red meat to waste fat. Cattle feeders live by numbers, says CAB. Gain, feed efficiency, rations and of course prices—each one matters to the ultimate bottom line, but there’s one figure that may be less understood among cow-calf producers. formula. Yield grades estimate the quantity or the amount of closely trimmed boneless retail cuts from the loin, round, chuck and rib. A yield grade 1 carcass provides the greatest amount of saleable beef while a yield grade 5 is the lowest-yielding carcass. Live Weight Beef cattle have a wider range of market weights compared to other species due to differences in type and maturity. Cattle Pricing Methods Live Dressed weight or “in the beef” Carcass grade and yield or grid pricing. An example yield grade stamp is provided in Figure 1.
