Study Notes

Fat Distribution and Eating Quality

Fat distribution refers to the coverage of subcutaneous fat on a carcass, affecting muscle chilling rates.
Even fat distribution is crucial for consistent chilling of muscles; uneven distribution leads to uneven chilling, risking cold-shortening or heat-shortening.
Greater fat depth results in slower, uniform chilling rates; inadequate coverage can trigger MSA specification failures.
Access to an increasing plane of nutrition for at least one month before slaughter helps achieve even fat coverage.

Fat Distribution Standards

Minimum rib fat requirement: 3mm.
Minimum P8 fat thickness: 5mm.
Fat distribution must be even and sufficient across the carcass to prevent chilling issues.

Consequences of Uneven Fat Coverage

Patches of fat removed during hide removal can unsettle muscle chilling rates, causing temperature inconsistencies within the carcass.
The resulting pH-temperature decline can lead to "two toning" in cuts, evident as variation in meat color.

Hide Puller Damage and MSA Grading

MSA accredited graders evaluate hide-puller damage primarily on major primals like cube roll, striploin, and rump.
Affected primals may be ungraded if damage occurs over a specified area (10cm x 10cm).
Processors must have documented procedures in the Quality Manual to exclude affected cuts and comply with MSA requirements.
