& / As a follow-up to my last week’s column, 1 thought I’d try to tackle the subject of how pork is evaluated. And, as in beef, I am going to fall back on the knowledge of the National Livestock and Meat Boad when it comes to the why’s and wherefores. In the past few years, the meat industry has seen rapid changes in the type of hogs' selected as grand champions at local fairs and state livestock shows. While on the hoof, these prize-winning hogs reflect the judge’s opinion on what is best, and this is hopefully based on the fisAl end-product that amftal was bred for - hams, pork chops, and bacon.

Purchase power tells the hog producer what tne families in the U.S. and worldwide want and demand m the pork products they buy. Since most hogs are marketed within a small weight range, the U.S.D.A. has been able to establish strict standards of how long the best slaughter hog should be, along with the amount of fat it carries, and the size of chops. Actually, they measure the area of the longissimus dorsi muscle at Farm Show Coliseum Harrisburg April 26-27, 1980 TRUCKS and ADVANCE TICKETS the tenth rib a rigid criteria. Hog breeders and com mercial hogmen have responded to the publics demand for less fat and more lean meat by trying to raise trimmer, meatier hogs. The leaner cuts have become more fashionable m our thin-conscious society, making ham, loin, and shoulder blade cuts most popular. According to NLMB’s Meat Evaluation Handbook, pork carcass evaluation is based on the expected yield of the four lean cuts ham, loin, arm picnic, and Boston butt. It also considers the quality of the lean the meat’s firmness and color, the amount of firmness of fat, and the meat’s marbling and texture. To refresh your memory, marbling is the speck flecks, or fat deposits m the muscle that adds juiciness and flavor to the meat. And texture is the size of the fiber bundles that make up the muscle, either coarse or fine. at $5.00 at $5.00 Reflecting the recent trends to low-fat diets, the NLMB reports that during the past twelve years, tests run by a Mid-west ex periment station have shown as increase of ham and loin percentage of carcass weight from 32.3 percent to 42.6 percent. The 1800 barrows measured also showed decrease in the amount of backfat, going from 1.64 inches thick to 1.25 inches thick. The loin eye, or muscle at the tenth nb, increased m area from 3.22 square inches to 4.74. The lean-cut yield of an individual hog is a direct relation to the amount of finish or fat on the carcass. Finish is measured by taking the average backfat thickness at three spots along the hog’s back at the first nb, last nb, and last lumbar vertebrae. NLMB suggests an average backfat thickness of about one inch to be op timum for a hog weighing 140 pounds, dressed.

Lancaster Farming, Saturday, March 29,1980—A17 After tat and percent lean cuts available from the hog carcass, the trained eye should look for the curve and bulge of the carcass. Hopefully, it will be plump in the nght spots, the ham, lorn, shoulder, and belly. NLMB points out the length of the carcass is not necessarily related to the carcass value or the amount of meat that it will produce being increased. However, length is used in the cer tification standards of pork carcasses. Let’s take a closer look at one of the favorite cuts in pork, the hams. Each hog comes equipped with two potential Easter or Christmas delicacies. Whether fresh or cured, there are certain things that make one ham better than another. What does a terrific ham look like. Well, once agam referring to the expert opinion of NLMB, a desirable muscled ham is both broad and deep with the Class A Grand National Circuit Event Entrance n n 0 2nd Choice XX meatiness extending toward the hock of the hog’s leg. This gives the consumer more of the most preferred ham section, the center steaks. And, the hams should not be covered with an excessive amount of fat, because in the commercial trade, this fat is trimmed off on the upper two-thirds of the ham, with the lower part left on. In either case, it means waste. NLMB goes on to describe the high-quality ham as one where the cut lean surface is firm, fine textured, and uniformly bright, greyish-pink. In cured hams, this color will be changed slightly through processing. The muscle should contain a uniform and extensive amount of firm, white marbling. The outside finish should also have the firm, white fat and it should be dry, with smooth skin. Variations in this high quality ham range m color from dark red, to almost pure grey, or the ham could be two-toned in color, with the meat becoming darker as it nears the bone. Inferior hams also tend to have a coarser texture and may appear soft and watery, a weeping ham. Getting back to the hog carcass as _ a whole, the process of grading involves all the points mentioned. But, it differentiates bet ween gilts and barrows, and sows. Boars and stags are left out of the grading system completely. In the gilts and barrow category, the carcasses are separated into two major areas those with ac ceptable or unacceptable lean. Those that are pulled off into unacceptable row are graded U.S. Utility. Their bellies may be too thin for bacon production, or they may have soft and oily carcasses which throw them into Utility regardless of other quality factors. Acceptable carcasses are divided into' U.S. No. 1 through No. 4. These U.S.D.A. grades are set up to estimate the percent of yield of the four lean cuts, with U.S. No. 1 yielding 53 percent or more, U.S. No. 2 yielding 50 to 52.9 percent, U.S. No. 3 with 47 to 49.9 percent, and U.S. No. 4 bringing up the tail end with everything less than 47 percent. As m any standard, there are variations and reasons for them. Judgment by Federal inspectors on the amount of fat, lean muscle, length, and muscling however, will be the final determining factor in the grading of pork carcasses. These grading standards help hog producers and consumers _ receive the benefits in cost and payment for the high quality pork marketed, and encourage producers of the inferior hog carcasses to improve in order to get top dollar.
