The marbling is scored in the ribeye muscle at the 12th rib. These eight quality grades of beef are shown below. The area of the ribeye is determined by measuring the size (in inches, using a dot-grid) of the ribeye muscle at the 12th rib. Quality grading on beef carcasses is determined by two subjectively scored factors in all cases where color, texture and firmness of lean are normal. If you find these calculators useful, please share them with your friends. PYG Adj. If you estimate an animal to be above average in muscling, the adjustment is subtracted from preliminary yield grade; if below average then the adjustment is added. In general, however, marbling scores are discussed in tenths within each degree of marbling (e.g.,Slight 90, Small 00, Small 10). h�b```��������� Only graders highly skilled in evaluating cutability of beef carcasses make these adjustments according to whether the measured fat thickness is representative of the fat coverage over the rest of the carcass. in. in., add .33 to the PYG. Carcasses with B, C, D, or E final maturity scores require an increasing amount of marbling as maturity increases to remain in the same quality grade. A good indication of total carcass muscle is the ribeye. WSU Livestock Carcass Grade & Cutability Calculator is a simple way to calculate carcass yield grade, dressing percentages, and cutability of beef, pork and lamb carcasses. Adjust for carcass weight deviations from 600 pounds. Adjust for percentage KPH deviations from 3.5 percent. Carcass weight of the animal can be calculated by estimating the animal's dressing percent and multiplying it by the live weight of the animal. Individuals can estimate yield grade or cutability from live animal data from cattle, pigs and lambs, in addition to calculating the actual dressing percentage and cutability for beef, pork and lamb carcasses from carcass data. Ounces As maturity proceeds from A to E, progressively more and more ossification becomes evident. Registered in England and Wales. Carcass weight is the “hot” or unchilled weight in pounds (taken on the slaughter-dressing floor shortly after slaughter). in., then it is probably more muscular then average, and the PYG should be adjusted down to lower the numerical value of the yield grade. Determine lean maturity by evaluating the color and texture of the lean in the ribeye exposed between the 12th and 13th ribs. Also evaluate the color and shape of the ribs. If a carcass has more than 3.5% KPH, then the carcass is fatter than the average and the PYG should be adjusted up, raising the numerical yield grade. Grams. The Calculator lets you determine: For cattle the Beef Carcass calculator will calculate estimated yield grade, dressing percentage, actual yield grade, percent retail cuts, and assist in determining USDA quality grade by reviewing USDA degrees of marbling standards for A maturity … A quality grade is a composite evaluation of factors that affect palatability of meat (tenderness, juiciness, and flavor).

If a carcass has a ribeye area greater than 11.0 sq. It is used to assess total fat on the carcass. The WSU Livestock Carcass Grade & Cutablity is an excellent way for producers, niche marketers, butchers, livestock judges, meat evaluators, and youth to quickly determine the yield grade and cutability of beef, pork or lamb carcasses. under 11.0 sq. A, the amount of kidney, pelvic, and heart fat; and. over 11.0 sq. The primary estimate of fatness is fat thickness at the 12th rib. It has been determined that the average carcass has 3.5% KPH. After the degree of maturity and marbling has been determined, these two factors are combined to arrive at the Final Quality Grade. 450 0 obj <> endobj Maturity Date Loan Calculator: Change these fields as desired: Principal Loan Balance : Annual Interest Rate (%) First Payment: Month ... (Estimated Taxes and Insurance are added to the principal and interest to calculate the total payment.) The USDA prediction equation for percent boneless, closely trimmed retail cuts (% BCTRC) of beef carcasses is as follows: Expected percentage of boneless, closely trimmed retail cuts from beef carcasses within the various yield grades. Degree of marbling is the primary determination of quality grade. Degree of marbling is the primary determination of quality grade. Most Steers and Heifers Processed in U.S. Fed Beef Plants Produce A-maturity Carcasses • 2004 Beef Checkoff Study (6,600 fed steers and heifers, < 30 mo. WSU Extension programs and employment are available to all without discrimination. 750 minus 600 = 150 / 25 = 6 X .1 = .6 (add), c. 3.5 minus 2.0 = 1.5 X .2 = .30 (subtract), d. 14.0 minus 11.0 = 3 X .33 = .99 (subtract), Pingback: Smoked Beef Rib Roast |, Pingback: Food Trivia...Is Prime Rib a Prime Cut of Meat or a Name for a Cut of Meat? For each 1.0 sq. in., subtract .33 from the PYG Determine lean firmness to ensure that the minimum degree of firmness specified for each maturity group is met. For cattle the Beef Carcass calculator will calculate estimated yield grade, dressing percentage, actual yield grade, percent retail cuts, and assist in determining USDA quality grade by reviewing USDA degrees of marbling standards for A maturity cattle carcasses (less than 30 months of age). h�bbd``b`�$� �$ ��$�l@DH�$��gW$qD( }�) YA q�##����H�A�+@� �2 Beef Magazine is part of the Informa Markets Division of Informa PLC.

Yield grade identifies the difference in the yield of lean red meat to waste fat based on the following scale: USDA 1 – Most desirable, trim It may assist the breeder to determine where animals best fit into a breeding program—whether, for example, a bull is better suited to producing vealers or steers.
