The rules provided for in this Part shall apply when the grading of pig carcasses is carried out by means of the apparatus termed `Intrascope` (Optical Probe).

The Intrascope shall be equipped with a hexagonal shaped probe with a maximum width of 12 mm (and of 19 mm at the blade on top of the probe) containing a viewing window and light source together with a sliding barrel.

$Y=\mathrm{68,1839}-\mathrm{0,55266}\times \mathrm{SP\_F1}$

where:

SP_F1 The thickness of the back fat including rind in mm, measured at 8 cm off the midline immediately behind the last rib

The formula shall be valid for carcasses weighing between 50 and 120 kg.

The rules provided for in this Part shall apply when the grading of pig carcasses is carried out by means of the apparatus termed ‘Hennessy Grading Probe 2 (HGP 2)’.

Hennessy probe reflectance spectroscopy records profiles of the measurements generated from recording in fractions of millimeters, distances of penetration together with back scattered light signals.

Specific optical band widths are selected to provide the optimum information obtainable between and within the various tissues of the species being objectively analyzed.

The apparatus Hennessy Grading probe shall be equipped with a probe of 5,95 mm diameter with an abutting blade of 6,3 mm containing a photodiode (Siemens LED of the type LYU 260-EO and photo detector of the type 58 MR) and having an operational distance between 0 and 120 mm.

The results of the measurements shall be transformed in terms of estimated lean meat content by means of the HGP2 itself as well as a computer linked to it.

$Y=\mathrm{68,9849}-\mathrm{0,61123}\times \mathrm{GP2\_F1}-\mathrm{0,28522}\times \mathrm{GP2\_F2}+\mathrm{0,0242}\times \mathrm{GP2\_M}$

where:

GP2_F1 The thickness of back fat including rind in mm, measured at 8 cm off the midline immediately behind the last rib GP2_F2 The thickness of back fat including rind in mm measured at 6 cm off the midline 12 cm towards the head compared with F1. GP2_M The thickness of the muscle in mm measured at the same time and in the same place as F2.

The formula shall be valid for carcasses weighing between 50 and 120 kg.

The rules provided for in this Part shall apply when the grading of pig carcasses is carried out by means of the apparatus termed ‘AutoFom III’.

The AutoFom III is based on ultrasound technology and provides a digitized 3-D scan of the carcass. The ultrasonic image is generated by 16 transducers embedded in a stainless steel array.

$Y=\mathrm{55,2971}-\mathrm{0,27747}\times \mathrm{R2P4}-\mathrm{0,24594}\times \mathrm{R2P11}+\mathrm{4,59557}\times \mathrm{R2P12}-\mathrm{0,22981}\times \mathrm{R2P15}+\mathrm{0,11882}\times \mathrm{R3P5}-\mathrm{0,11719}\times \mathrm{R4P3}$

where:

R2P4 p2_selected_fat_mm. The P2 fat measure at the selected position in mm. R2P11 minpair_value. A filter mask that selects two regions 14 cm apart is applied to the cross-section vector. This is the minimum of the filter result vector. R2P12 P2_skew. Relation of the selected P2 and the unselected P2. The actual point used is a little closer to the center, to make the value more tolerant to very tilted carcasses. Value is always greater than or equal to 1,0. R2P15 minpair_value v2. A second version of the minpair value.

The formula shall be valid for carcasses weighing between 50 and 120 kg.

The rules provided for in this Part shall apply when the grading of pig carcasses is carried out by means of the apparatus termed ‘Fat-O-Meat'er II’ (FOM II).

The apparatus is a new version of the Fat-O-Meat'er measurement system. The FOM II consists of an optical probe with a knife, a depth measurement device having an operating distance of between 0 and 125 millimetres and a data acquisition and analysis board — Carometec Touch Panel i15 computer (Ingress Protection IP69K). The results of the measurements are converted into estimated lean meat content by the FOM II apparatus itself.

$Y=\mathrm{68,5549}-\mathrm{0,5485}\times \mathrm{FOM\_F1}-\mathrm{0,26491}\times \mathrm{FOM\_F2}+\mathrm{0,0153}\times \mathrm{FOM\_M}$

where:

FOM_F1 the thickness of backfat in mm, measured at 8 cm off the midline of the carcass between the third and fourth last lumbar vertebrae. FOM_F2 the thickness of backfat in mm, measured at 6 cm off the midline of the carcass between the third and fourth last ribs. FOM_M the thickness of muscle in mm, measured at the same time and in the same place as F2

The formula shall be valid for carcasses weighing between 50 and 120 kg.

The rules provided for in this Part shall apply when the grading of pig carcasses is carried out by means of the apparatus termed ‘Hennessy Grading Probe 7 (HGP 7)’.

Hennessy probe reflectance spectroscopy records profiles of the measurements generated from recording in fractions of millimeters, distances of penetration together with back scattered light signals.

Specific optical band widths are selected to provide the optimum information obtainable between and within the various tissues of the species being objectively analyzed.

The apparatus Hennessy Grading probe shall be equipped with a probe of 5,95 mm diameter with an abutting blade of 6,3 mm containing a photodiode (Siemens LED of the type LYU 260-EO and photo detector of the type 58 MR) and having an operational distance between 0 and 120 mm.

The results of the measurements shall be transformed in terms of estimated lean meat content by means of the HGP7 itself as well as a computer linked to it.

The evaluation of the measuring curve slightly differs between HGP 2 and HGP 7.

GP7_F1 The thickness of back fat including rind in mm, measured at 8 cm off the midline immediately behind the last rib GP7_F2 The thickness of back fat including rind in mm measured at 6 cm off the midline 12 cm towards the head compared with F1. GP7_M The thickness of the muscle in mm measured at the same time and in the same place as F2.

The formula shall be valid for carcasses weighing between 50 and 120 kg.
