WEIGHT CLASSIFICATION GRID
LABELLING OPTIONS
WEIGHT AND FAT CLASSES (Scores):
Porcine carcases over 25kg (HSCW) may be classified into weight
related fat classes.
The weight classes are based on HSCW. The fat classes are decided by
measuring the external fat covering, plus the skin at the P2 site.
The following table shows the relationship between the weight and fat
classes:

The image of the Carcase (above) is trimmed to the Standard Carcase Definition. There are many combinations of carcase trim. In
order to ensure fair trading irrespective of trim a Conversion Factor has been included.
THE CONVERSION FACTOR FOR THE STANDARD CARCASE DEFINITION IS (1).
* See over page for Standard Carcase trim conversion grid.
STANDARD CARCASE TRIM DEFINITION (1)
Other than Sucker Pork and skin-off carcases, a Pigmeat
Carcase is the body of a slaughtered porcine animal after:
u bleeding
u removal of all the internal digestive,respiratory, excretory,
reproductive and circulatory organs
uminimum trimming as required by meat inspection service for
the carcase to be passed fit for human consumption.
And the removal of the:
u hair and scurf
u hooves of the foretrotters and of the hindtrotters
u testes and penis
uears, eyelids/lashes, facial hair and tongue
u kidneys and kidney fat
The Carcase must be weighed hot (HSCW)
uAUS-MEAT accredited abattoirs may trim carcases to any
one of 24 trim options.
u However operators must report all pig carcase weights in
terms of the Standard Carcase Definition (Trim No.1).
uThe Standard Conversion chart on the next page has been
developed for conversion of non-standard carcases back
to the Standard Carcase Definition. This means reporting
of carcase weights to producers is on a uniform and
comparable basis.
u There are separate conversion charts for heavier pigs (over
60kg dressed weight) and lighter carcases.
HEAD REMOVAL and SKULL OUT
Where Trim Options specify ‘Head Off’ or ‘Skull Out’, the following dressing procedures apply:
uHead Off: The head is removed between the occipital bone and the 1st cervical vertebrae by a square cut transversely across
the neck muscles.
uSkull Out: A cut commencing at the lower jaw under the chin follows the jaw bone through to the neck joint ensuring cheek muscles are retained on the jowl. The snout and portions of skin retained on the lower jaw near the mouth remain on the skull. The
skull is removed by a cut through the occipital bone and the 1st cervical vertebrae.
