E- White, nonporous, extremely hard, A- Narrow and oval Beef Yield Grades. It has been determined that the average carcass has 3.5% KPH. The fundamentals involved in applying quality grades are learning the degrees of marbling in order from lowest to highest and minimum marbling degrees for each maturity group and understanding the relationship between marbling and maturity in each quality grade. (PDF, 514 KB). A quality grade is a composite evaluation of factors that affect palatability of meat (tenderness, juiciness, and flavor). The USDA Yield Grades are rated numerically and are 1, 2, 3, 4, and 5. in., subtract .33 from the PYG, For each 1.0 sq. Hot carcase . Based on this fat thickness, a preliminary yield grade (PYG) can be established. Additional Resources, Site Policies The first three quality grades Prime, Choice and Select are the most commonly recognized by consumers and are considered food-grade labels by USDA. (3) the amount of kidney, pelvic, and heart fat; and Submit a request to be listed for FREE in the Buyers Guidehere. in. USDA 2. A yield grade 4 has eight-tenths (.8") of an inch fat thickness. (2) the hot carcass weight; Beef carcass yield grades (YG) are used to estimate cutability, which is the amount of boneless, closely trimmed retail cuts from the round, loin, rib and chuck a carcass will yield. Condition of the bodies of the split chine bones: A- Red, porous and soft in. Select grade for B maturity carcasses. 3. Adjust for carcass weight deviations from 600 pounds. Fat thickness is measured at a point three- fourths of the distance of the length of the ribeye from its chine bone side (Figure 4). under 11.0 sq. Graders evaluate the amount and distribution of marbling in the ribeye muscle at the cut surface after the carcass has been ribbed between the 12th and 13th ribs. (4) the area of the ribeye muscle. C- Tinged with red, slightly hard In youthful animals, there is a button of cartilage on the top of each bone in the vertebral column (backbone). It's What's For Dinner. A quality grade is a composite evaluation of factors that affect palatability of meat (tenderness, juiciness, and flavor). As an animal matures, the texture of the lean becomes progressively coarser and the muscle color becomes darker. Thus the cartilage between and on the dorsal edges of the individual sacral and lumbar vertebrae as well as the cartilage located on the dorsal surface of the spinous processes of the thoracic vertebrae (buttons). In terms of chronological age, the buttons begin to ossify at 30 months of age. These factors include carcass maturity, firmness, texture, and color of lean, and the amount and distribution of marbling within the lean. a. 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. If the average of the lean and bone maturities doesnt move across the B/C line from the bone maturity side (e.g., Bone = B and Lean = C with the average being B or Bone = C and Lean = B with the average being C); average the two maturities and adjust the average to the nearest 10% toward the bone. B- Slightly red and slightly soft When the percentage ossification of the cartilage reaches 10, 35, 70, and 90 percent, the maturity is B, C, D, and E, respectively. They have been used by the beef industry since 1927. and Merkel, R.A. Live Animal, Carcass Evaluation and Selection Manual. It has been determined that the average carcass has 3.5% KPH. Usually, there is a slightly thin layer of fat over the inside round, loin, and rib, with a slightly thick layer of fat over the rump and sirloin. Select grade for B maturity carcasses. USDA Beef Grading Chart: Relationship Between Marbling, Maturity and Carcass Quality Grade1. Example yield grade problem using the short cut method: b. d. 14.0 minus 11.0 = 3 * .33 = .99 (subtract), 3.25 PYG As an animal matures, the characteristics of muscle change, and muscle color becomes darker and muscle texture becomes coarser. Yield grade 2; Yield grade 3; Yield grade 4; Yield grade 5; Within the five yield grades, USDA yield grade 1 has the highest % BCTRC, and grade 5 has the lowest . Take a look at how the following traits are . b. Yield Grade 2 The carcass is almost completely covered with external fat, but lean is very visible through the fat over the outside of the round, chuck, and neck. These factors include carcass maturity, firmness, texture, and color of lean, and the amount and distribution of marbling within the lean. Thus the cartilage between and on the dorsal edges of the individual sacral and lumbar vertebrae as well as the cartilage located on the dorsal surface of the spinous processes of the thoracic vertebrae (buttons). The more fat opposite the ribeye, the higher the numerical value of the PYG. There are indications that the upper yield grade 3''s may be discounted in the future. Because the chronological age is virtually never known, physiological maturity is used; and the indicators are bone characteristics, ossification of cartilage, color and texture of ribeye muscle. Desirable ribeyes will exhibit an adequate amount of finely dispersed marbling in a firm, fine textured, bright, cherry-red colored lean. Measure the amount of external fat opposite the ribeye. While the grading system is voluntary, virtually all [] Packers do not buy fat, and add premiums to the yield grade 2 and discount the yield grade 3. Wagyu is combined with the yield score (Usually "A" for Wagyu breeds) to give the ratings of A1 to A5. In no case may overall maturity be more than one full maturity group different than bone maturity. Step-Wise Procedure for Quality Grading Beef Carcasses. Yield Grade 5. Ribs are quite round and red in A maturity carcasses, whereas E maturity carcasses have wide and flat ribs. Below are two tables to help determine required REAs. B60 + Md40 = Cho. Determine lean firmness to ensure that the minimum degree of firmness specified for each Marbling (intramuscular fat) is the intermingling or dispersion of fat within the lean. Yield Grade 5 Generally, the carcass is covered with a thick layer of fat on all external surfaces. Characteristics of Beef Cattle Operations, Statistics on US improvements in beef production and emission intensity, U.S. vs. Method of measuring Ribeye area. Determine lean maturity by evaluating the color and texture of the lean in the ribeye exposed between the 12th and 13th ribs. Beef carcass yield grades (YG) are used to estimate cutability, which is the amount of boneless, closely trimmed retail cuts from the round, loin, rib and chuck a carcass will yield. Your email address will not be published. Balancing lean maturity and bone maturity: 1. For each 1 in.2 more than the required REA, subtract 0.3 from the PYG. When the percentage ossification of the cartilage reaches 10, 35, 70, and 90 percent, the maturity is B, C, D, and E respectively. Each degree of marbling is divided into 100 subunits. 0.5 in. Beef Carcass Yield Grades: What do they mean and how are they calculated? A1 carcasses were those with a fat thickness of five to 10 mm. Graders evaluate the amount of external fat at the 12th rib by measuring the thickness of fat three-fourths the length of the ribeye from the chine. Canada 1 is the highest grade, with an estimated 52.3% or more of the carcass being usable meat, while Canada 5 is the lowest, with an estimated 45.5% or less of the carcass being usable. A carcass with no fat opposite to ribeye has a PYG of 2.00, For each .1 inch of fat add .25 to the PYG, For each 25 pounds over 600 pounds, add .10 to the PYG, For each 25 pounds under 600 pounds, subtract .10 from the PYG, For each 1%KPH over 3.5%, add .20 to the PYG, For each 1%KPH under 3.5%, subtract .20 from the PYG, For each 1.0 sq. Yield Grade 1 denotes the highest yielding carcass and Yield Grade 5, the lowest. Yield Grade 4 The carcass is usually completely covered with external fat, except that muscle is visible in the shank, outside of the flank and plate regions. Carcasses are stratified into five maturity groups, based on the estimated age of the live animal, Color and Texture As maturity increases, lean becomes darker in color and coarser in texture. Each degree of marbling is divided into 100 subunits. AB = Abundant; MAB = Moderately Abundant; SLAB = Slightly Abundant; MD = Moderate; MT = Modest; SM = Small; SL = Slight; TR = Traces; PD = Practically Devoid. Dubuque, IA: Kendall/Hunt Publishing Company, 1990. Yield Grades. Preliminary YG measurements start at 2.0, and 0.25 is added to the PYG measurement for every 0.1 inches of backfat (Table 1). and Standards for Grades of Carcass Beef (USDA, 1996), which are designed to facilitate beef marketing by separating a highly variable population of live cattle and/or beef carcasses into groups which are more uniform in quality and composition. There are some grades for WAGYU beef, including the meat of Japanese Black, and A5 is the highest grade given only to the finest beef. The sacral vertebrae (rump portion of the carcass) show first signs of ossification. The base PYG is 2.00. In the current market, yield grades of 4 are undesirable and discounted on price. We expect a YG 1 carcass to have the highest percentage of boneless, closely trimmed retail cuts . South Dakota State University, South Dakota counties, and USDA cooperating. Carcass Characteristics: Last week's Industry At A Glance focused on quality grade trends over time. Beef carcasses may carry a quality grade, a yield grade or both a quality and yield grade. As cattle mature, their meat becomes progressively tougher. Adjust for ribeye area (REA) deviations from 11.0 sq. Evaluate the marbling in the ribeye and determine the marbling score. It is also known as cutability. 95% or more get a quality grade. The USDA prediction equation for percent boneless, closely trimmed retail cuts (% BCTRC) of beef carcasses is as follows: If a carcass has less than 3.5% KPH, then the carcass is leaner than average and the PYG should be adjusted down, thus lowering the yield grade. Overall Maturity + Marbling Score = USDA Quality Grade USDA Quality Grades are used to reflect differences in expected eating quality among slaughter cattle and their carcasses. 3. The U.S. Department of Agriculture (USDA) has established Standards for Grades of Slaughter Cattle Skeletal Maturity + Lean Maturity = Overall Maturity Through our yield grades, individual animal value is determined, which also affects profitability. The average carcass has a ribeye area of 11 sq. If a carcass has a ribeye area greater than 11.0 sq. B- Slightly wide and slightly flat The quality score ranges from 1-12, which includes factors like marbling and color. What are the 5 yield . The standards of grading beef consist of Yield Grade and Quality Grade. USDA Yield Grade 3 in., add .33 to the PYG. 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. Table illustrating the minimum marbling score requirements for USDA quality grades within each final maturity group. These factors include carcass maturity, firmness, texture, and color of lean, and the amount and distribution of marbling within the lean. Minus 0.46 (Percentage KPH fat) 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. South Dakota State University adheres to AA/EEO guidelines in offering educational programs and services. Fall brings many weaning and selling time decisions for cattle operations. If the ribeye area is less than 11.0 in., then the carcass is probably less muscular than average and the PYG should be adjusted up. The same holds true for the Graders determination of the USDA Quality Grade. Beef Quality Grades. After maturity and marbling are determined, these two factors are combined to determine USDA Quality Grade. There is a posterior-anterior progression in maturity. ANSC 437 Marketing and Grading of Livestock and Meat, Z.L. The normal range is .15-.8 inches with an average of .5 in. A quality grade is a composite evaluation of factors that affect palatability of meat (tenderness, juiciness, and flavor). in. "2Maturity increases from left to right (A through E).3The A maturity portion of the figure is the only portion applicable to bullock carcasses. Color and texture of the longissimus muscle are used to determine carcass maturity when these characteristics differ sufficiently from normal. Below is an example of how to calculate a YG using this method. Thus, ossification begins in the sacral region and with advancing age proceeds to the lumbar region and then even later it begins in the thoracic region (buttons) of the carcass. Adjust for carcass weight deviations from 600 pounds. Yield Grade Yield grade is an estimate of the percent retail yield of the four primal cuts of beef (chuck, rib, loin and round). During maturation, these regions of cartilage gradually change to bone (ossify). The USDA Yield Grades are rated numerically and are 1, 2, 3, 4, and 5. These factors include carcass maturity, firmness, texture, and color of lean, and the amount and distribution of marbling within the lean. | Morning Ag Clips, Pingback: Camp Brisket, 2016 edition - Texas Barbecue, Pingback: The Ultimate Meat Cheat Sheet: Beef, Your email address will not be published. Backfat is converted into a preliminary YG (PYG) value. Site Policies, 2022 Cattlemen's Beef Board and National Cattlemen's Beef Association. The five Yield Grades for slaughter cattle and beef carcasses are: USDA Yield Grade 1 The grader usually writes this weight on a tag or stamps it on the carcass. Because of this posterior-anterior progression of ossification, even young A maturity carcasses will have some ossification in the sacral cartilage. Award-winning coverage of in-depth news and analysis to make your business more profitable. If you do not have a calculator on hand, YGs can be calculated using a series of adjustments based on BF, REA, KPH and HCW. Yield Grade 1 denotes the highest yielding carcass and Yield Grade 5, the lowest. As an animal matures, the characteristics of muscle change, and muscle color becomes darker and muscle texture becomes coarser. Degree of marbling is the primary determination of quality grade. The resulting area is the area of the ribeye in square inches. The column noted that, "Quality grading has been nothing short of phenomenal thus far in 2019. B60 + A80 = B30 (>40; 10% to bone) The USDA system grades beef on two criteria. The more fat opposite the ribeye, the higher the numerical value of the PYG. Many are familiar with the story of Goldilocks and the three bears, where Goldilocks tries to find a bed that's not too hard, nor too soft, but just right. Learn how this same concept can help producers find a carcass size that's "just right" for bison processing. There are eight beef quality grades: Prime, Choice, Select, Standard, Commercial, Cutter & Canner. There are eight total quality grades: Prime, Choice, Select, Standard, Commercial, Utility, Cutter and Canner. How do I get my company listed in your Buyers Guide? A quality grade is a composite evaluation of factors that affect palatability of meat (tenderness, juiciness, and flavor). In general, however, marbling scores are discussed in tenths within each degree of marbling (e.g.,Slight90, Small00, Small10). Determine age using thoracic buttons. Carpenter Outstanding Graduate Student Award in Meat Science, Aron and Mary Lois Savell Leadership Mentor Program, National Beef Quality Audit 2016 resource page, Standardized Warner-Bratzler Shear Force Procedures for Genetic Evaluation, NAMA Center of the Plate Training hosted by Texas A&M University, June 4-6, 2013, Making Some Sense Out of Ground Beef Labeling, Meat market managers trained to educate consumers on beef products, Food TriviaIs Prime Rib a Prime Cut of Meat or a Name for a Cut of Meat? In terms of yield grade, a yield grade 1 carcass yields the most saleable beef, while a yield grade 5 carcass yields the least quantity of sellable meat. A yield grade 1 carcass provides the greatest amount of saleable beef while a yield grade 5 is the lowest-yielding carcass. If a carcass weighs more than 600 pounds, then we increase the PYG, and if a carcass weighs less than 600, then we decrease the PYG. in., then the carcass is probably less muscular than average and the PYG should be adjusted up. What is yield grade meat? Texas A&M College of Agriculture and Life Sciences, Dan S. Hale, Kyla Goodson, and Jeffrey W. Savell. If the bone and lean maturities are not considerably different, but one is in B maturity and the other in C maturity and the average of the two moves across the B/C line from the bone maturity side, the overall maturity will be on the side of bone maturity it will be either B-100 or C-00. under 11.0 sq. For each 1.0 sq. In addition to the quality grade, beef carcasses are also given a yield grade, which ranges from 1-5 and estimates the amount of usable meat on each carcass. Questions? Because the chronological age is virtually never known, physiological maturity is used; and the indicators are bone characteristics, ossification of cartilage, color and texture of ribeye muscle. Firmness of muscle is desirable, as is proper color and texture. Adjust for percentage KPH deviations from 3.5 percent. Determine the preliminary yield grade (PYG). The information collected through the grading process is used in making marketing and production decisions. Color and texture of the longissimus muscle are used to determine carcass maturity when these characteristics differ sufficiently from normal. It is also known as cutability. Most carcasses have 1% to 4% of the carcass weight represented as kidney, pelvic and heart fat. Carcass weight: 750 lbs. E- Wide and flat, Color and Texture As maturity increases, lean becomes darker in color and coarser in texture. Cartilage becomes bone, lean color darkens and texture becomes coarser with increasing age. in. It is also looking at how much useable lean meat a carcass can produce. For every 25 pound increase in HCW, the required ribeye area increases by 0.3 in.2. A quality score of 8-12 qualifies as the best of the beef, ranking it at a final quality score of 5. 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 . The relationship between ribeye area and carcass weight is used in Yield Grading beef carcasses to reflect differences in cutability stemming from carcass muscularity. Table 1. Assistant Professor and SDSU Extension Meat Science Specialist. The following descriptions will help you understand the differences between carcasses from the five yield grades: Yield Grade 1 The carcass is covered with a thin layer of external fat over the loin and rib; there are slight deposits of fat in the flank, cod or udder, kidney, pelvic and heart regions. Yield grade is an estimate of the percent retail yield of the four primal cuts of beef (chuck, rib, loin and round). The base PYG is 2.00. Use a simple average when bone and lean maturities are within 40 units of each other. In youthful animals, the lean tissue is fine-textured and light pinkish-red in color. By continuing to browse the site you are agreeing to our use of cookies in accordance with our. Yield grade is an estimate of the percent retail yield of the four primal cuts of beef (chuck, rib, loin and round). Maturity refers to the physiological age of the animal rather than the chronological age. Plus 0.74 (Ribeye area, in. = 3.25 Extensive fat is found in the brisket, cod or udder, kidney, pelvic and heart regions. D- Rather white, moderately hard While the USDA Grader may use this equation occasionally, most determinations are based upon the Graders experience and training, checking occasionally with the formula when requested to do so. Sell the Feeder Calf, or Create a Yearling? For fed cattle four grades were provided: Canada A1, A2, A3 and A4. Determine carcass skeletal maturity by evaluating the degree of skeletal ossification in the top three thoracic vertebra (buttons), and the sacral and lumbar vertebra. The grades are based on two main criteria: the degree of marbling (intramuscular fat) in the beef, and the maturity (estimated age of the animal at slaughter). The following descriptions will help you understand the differences between carcasses from the five yield grades: 1. USDA Yield Grade 2 FIGURE 2. It is relevant to note that although higher yield grades show there is more meat on the carcass, it does not necessarily mean that any particular beef cut will be of higher eating . It's What's For Dinner. Firmness of muscle is desirable, as is proper color and texture. As a general rule, the Prime, Choice, Select and Standard grades are restricted to beef from young cattle (A or B maturity; however, B maturity cattle are not eligible for the Select grade). The relationships between marbling and maturity used to determine the Quality Grade of a carcass are presented in Figure 2. The grade factors in . This single measurement is a reasonably accurate predictor of overall carcass fatness; however, to improve the accuracy of the predictions of overall carcass fatness, the fat thickness measurement usually is adjusted up or down by the grader to account for visible differences in the distribution of external fat in other areas of the carcass. Yield grade identifies the difference in the yield of lean red meat to waste fat based on the following scale: Beef quality refers to the expected eating characteristics (tenderness, juiciness and flavor) of the cooked product.
