Study Notes

Livestock Harvest & Red Meat Production: Grading, Fabrication & Marketing

Beef Grading

Operates on a grid pricing system.
Uses two primary grading categories for market guidance: beef yield grade and beef quality grade.
Yield grades estimate the quantity of edible product on a beef carcass.
Expressed numerically from 1.0 to 5.9:
- 1.0 indicates a very high-quality carcass.
- 5.9 indicates a very low-quality carcass.

Factors for Beef Yield Grades

Hot carcass weight (HCW).
12th rib fat thickness (FT).
Ribeye area (REA).
Kidney, pelvic and heart fat (KPH).
USDA equation for yield grade calculation:
- YG = 2.5 + (2.5 x FT) + (0.2 x KPH) + (0.0038 x HCW) - (0.32 x REA).

Beef Quality Grades

Predicts the likelihood of a desirable eating experience for consumers.
Based on a quality score derived from:
- Marbling (intramuscular fat) within the ribeye.
- Carcass maturity.

Lamb Grading

Operates under a similar grid pricing system as beef.
Uses two estimates: lamb yield grade and lamb quality grade.
Yield grades for lamb range from 1.0 to 5.9, similar to beef.

Lamb Yield Grades

Based on one primary factor: fat thickness (FT).
USDA equation for yield grade calculation:
- YG = (FT x 10) + 0.4.

Lamb Quality Grades

Predicts the likelihood of providing a good eating experience based on:
- Carcass conformation.
- Marbling streakings.

Pork Grading

Lacks established value-based pricing market comparable to beef and lamb.
Estimates include:
- Percent muscle.
- U.S. grades.

Percent Muscle in Pork

Equivalent to USDA yield grading.
Considers hot carcass weight (HCW), 10th rib fat thickness (FT), and loin eye area (LEA).
Calculation:
- Percent Muscle = 7.231 + (0.437 x HCW) + (3.877 x LEA) - (18.746 x FT).

U.S. Grades for Pork

Predict yield from pork carcasses, assigned by USDA Agricultural Marketing Service.
Graded on a scale of 1 to 4:
- 1 indicates high yield; 4 indicates low yield.
Factors include last rib fat thickness (LRBFT) and muscle score (MS).

Pork Quality

Currently lacks standardized quality grading but can be assessed for quality predictions based on similar principles.

Dressing Percentage

Used alongside yield grades to estimate carcass yield.
Defined as the portion of a live animal that becomes marketable meat.
Factors include hot carcass weight (HCW) and live weight (LW).
Calculation:
- Dressing Percentage = HCW ÷ LW.

Fabrication in Meat Processing

Fabrication Overview

Involves breaking down carcasses into primal cuts, sub-primal cuts, and retail cuts.
Essential for marketing and consumer access to various meat products.

Description of Cuts

Primal cuts refer to the main sections of the carcass.
Sub-primal cuts are smaller sections derived from primal cuts.
Retail cuts are the final pieces sold to consumers.

By-products

Refers to secondary products made from livestock which are vital in various industries (e.g., leather, gelatin).### Fabrication Process
Fabrication involves breaking down the carcass into retail cuts for consumer consumption.
The process breaks down beef, pork, and lamb into primal, sub primal, and retail cuts.
Primal cuts are larger cuts of meat derived from the initial breakdown of the carcass.
Sub primal cuts refer to smaller cuts fabricated from the primal cuts.
Retail cuts are the final product, ready for preparation and consumption.

Beef Primal Cuts

Chuck: Extends from the neck to the fifth rib; includes retail cuts like pot roast and top blade steak.
Rib: Fabricated from ribs 6-12 and a portion of the backbone; commonly used for ribeye steak and rib roast.
Loin: Contains the short loin and all lumbar vertebrae; leads to cuts like loin steak and tenderloin steak.
Round: Less tender, comes from the beef carcass's rear; includes cuts like round steak and bottom round rump roast.
Flank: Located beneath the loin, includes tougher cuts with significant fat; includes flank steak and London broil.
Brisket: Found on the ventral side of the carcass; consists of a tough, fatty cut with retail cuts like short ribs and whole brisket.

Pork Primal Cuts

Ham: Comprises the rump and hind leg; retail cuts include center slice and smoked ham.
Loin: Located on both sides of the spine; includes loin chop and rib chop as retail options.
Shoulder: Positioned on the upper and lower portion of the shoulder; includes arm steak and blade steak.
Belly: Ventral to the ribs, high-fat content; retail cuts include spareribs and fresh side.

Lamb Primal Cuts

Loin: Retail cuts include center slice and sirloin chop; versatile for various cooking methods.
Rack: Positioned between the loin and leg; retail cuts include rib chops and loin roast.
Shoulder: Contains ribs 1-4 and part of the carcass; includes arm chops and blade chops.

By-Products

By-products are secondary animal products used in other products.
Commonly recognized by-products include animal fat, connective tissues, and hides.

Meat Sales & Marketing

Marketing aims to increase meat sales and enhance consumer experience.
Programs classify carcasses based on quality to meet consumer expectations.
Boxed beef programs are the most prevalent in meat marketing, emphasizing yield and quality.

Premium Programs

Premium lamb and pork programs focus on sorting carcasses based on fat content and quality grades.
Premium pork programs emphasize leanness due to the lack of an official pork quality grade.

Retail Supply Chains

Focus on direct marketing to consumers through grocery stores.
Brand recognition plays a significant role in consumer satisfaction and product variation.

Food Service Supply Chains

Market meat to consumers through prepared settings like restaurants and cafeterias.
Less variation in consumer satisfaction due to consistent quality and cooking practices.

Export Markets

Crucial for the meat industry, providing cuts less favored by local consumers to areas where they are in demand.
Enhances carcass value by meeting global consumer demand for various meat products.
