ANNEX
Methods for grading pig carcases in Cyprus
Hennessy Grading Probe (HGP 4)
1.
Grading of pig carcases is carried out by means of the apparatus called ‘Hennessy Grading Probe (HGP 4)’.
2.
The apparatus shall be equipped with a probe of 5,95 millimetres diameter (and of 6,3 mm at the blade of the top of the probe) containing a photodiode (Siemens LED of the type LYU 260-EO) and photodetector of the type 58 MR and having an operating distance of between 0 and 120 millimetres. The results of the measurements shall be converted into estimated lean meat content by means of the HGP 4 itself or a computer linked to it.
3.
The lean meat content of the carcase shall be calculated according to the following formula:
where:
ý = the estimated percentage of lean meat in the carcase,
X 1
= the thickness of back-fat (including rind) in millimetres, measured at 8 cm off the midline of the carcase behind the last rib,
X 2
= the thickness of back-fat (including rind) in millimetres, measured at 6 cm off the midline of the carcase between the third and fourth last rib,
W = the thickness of muscle in millimetres, measured at the same time and in the same place as X 2 .
The formula shall be valid for carcases weighing between 55 and 120 kilograms.
