    dards for Grades of Carcass Beef on June 3, (USDA, ). The official standards for grades of lamb and mutton carcasses were published initially and made effective on Febru (USDA, ). Tentative pork grading standards were issued in and revised in The. BEEF MARBLING According to the results of a market survey on carcass distribution by the degree of marbling, the majority were classified in the range of "1- to 1 ". This range was regarded as "Grade 3" and about 40% of marketed carcasses were included in this grade. Then, beef marbling was divided into 5 grades so as to center around the.

      One standard method for the assessment of marbling is described in “Marbling Standards for beef and pork carcasses, S. D. M. Jones et al., Agriculture Canada Publication, ”. Although fat-marbled beef (i.e. beef with an intermingling or dispersion of fat within it) is in great demand especially in Japan because of its tenderness, fine.   A simple index that reflects the potential eating quality of beef carcasses is very important for producer feedback. The Meat Standards Australia (MSA) Index reflects variation in carcass quality due to factors that are influenced by producers (hot carcass weight, rib fat depth, hump height, marbling and ossification scores along with milk fed veal category, direct or saleyard consignment.

    U.S. Prime beef is sold to hotels and upscale restaurants, and usually marketed as such. In , the official standards were revised to restrict the Select grade to A maturity carcasses, and to raise the minimum marbling score to qualify for Choice to modest for B maturity cattle. A beef carcass exhibiting small marbling and B maturity would receive what overall quality grade? President Theodore Roosevelt brought about the enactment and passage of what act in response to Upton Sinclair's book, The Jungle? 7-bone pot roast, blade roast, blade steak, blade chop Percent muscle calculations in pork carcasses accounts.

U.S. 1 barrow and gilt carcasses must have less than average backfat thickness over the last rib with average muscling, or average backfat thickness over the last rib coupled with thick muscling. Traditionally, it has been believed marbling was coincidental with higher degrees of carcass fatness.

However, recent research, with both beef and pork have shown only % of the variation in marbling is accounted for by subcutaneous fat thickness (Jones et al., ).Consequently, no amount or duration of high energy feeding prior to slaughter will increase marbling score if an animal has a.

Food Standards and Labeling Policy Book Artificial Marbling - Red Meat Products. Aging is the process by which fresh beef (carcasses or cuts) are held in a controlled environment for a specified period of time of slaughter, to allow enzymatic activity t degrade complex proteins and promote the development of flavor and tenderness.

For example, in the United States, pork marbling is classified by professional inspectors into 7 grades (Table 1) according to the marbling standards of the Natl. Pork Producers Council (NPPC), which depict intramuscular fat (IMF) content and distribution from low to high with marbling scores from (devoid) to (abundant) (NPPC a.

A carcass in Yield Grade 1 usually has only a thin layer of external fat over the ribs, loins, rumps, and clods, and slight deposits of fat in the flanks and cod or udder.

There is usually a very thin layer of fat over the outside of the rounds and over the tops of the shoulders and necks.

However, it has been demonstrated 8mm of subcutaneous fat in combination with a small degree of marbling will provide 90% acceptance of beef palatability (Jeremiah ). Pork carcasses have been observed to contain substantial variability in both carcass and palatability traits (De Vol et.

Beef carcass quality grading is based on (1) degree of marbling and (2) degree of maturity. Marbling - (intramuscular fat) is the intermingling or dispersion of fat within the lean. 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.

The results should be compared to National Pork Board recommendations that color should be in a range of to and intramuscular fat “marbling” should be in the range of 2 to 4. In conclusion, these results demonstrate that a significant proportion of U.S.

pork fails to meet standards. A.V. Fisher, C.R. Helps, in Improving the Safety of Fresh Meat, Fate of the spinal cord. Beef carcasses are split down the median plane to yield two half-carcasses or ‘sides’.

The reasons for doing this are pragmatic and are mainly concerned with subsequent ease of handling of the product: intact carcasses commonly weigh in excess of kg, sometimes considerably more for.

If the carcass is skinned, the weight of skinned carcasses should bedivided by to convert to skin on basis. In cases where the carcass has been trimmed, carcass weight should be adjusted to compensate for the trim.

Beef fabrication. Steers and heifers average kilograms at slaughter and produce carcasses weighing kilograms (63 percent yield of live weight). Beef carcasses are split into two sides on the slaughter floor. After chilling, each side is divided into quarters, the forequarter and hindquarter, between the 12th and 13th ribs.

Prime. This is the highest grade of beef with the most fat meat is very tender and only accounts for about percent of all graded beef.

If, for example, the minimum marbling requirement for the U.S. Choice grade in beef were reduced from percent (described as a Small amount of marbling in official USDA quality grade standards) to percent (a Slight amount), time-on-feed could be reduced by about 30 days and percentage of fat in the carcass by about 10 percentage points.

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). Marbling is also important for export standards used for pork sold to Japan and other Asian nations.

Fig. shows marbling standards used by exporters of quality pork cuts from the United States. Japan importers of US pork will pay a premium for highly marbled cuts. The same marketing concepts for marbling apply to beef exported to Japan.

BEEF and VEAL - MEAT COLOUR Meat Colour is the predominant colour of the rib eye muscle (M. longissimus dorsi). Meat colour (Beef and/or Veal) is assessed on the chilled carcase at the bloomed rib eye muscle area (M.

Fewer carcasses are grading choice or better.
