paragraphs: The Pig Carcase (Grading) Regulations, 1988 ( S.I. No. 365 of 1988 ), are hereby amended with effect from the commencement of the Regulations of 1993 by the substitution for Annex II (inserted by the Regulations of 1993) of the following Annex:
"ANNEX II
METHODS FOR GRADING PIG CARCASES IN IRELAND
PART I
FAT-O-MEATER (FOM)
num: 1
paragraphs: Grading of pig carcases is carried out by means of the apparatus termed "Fat-O-Meater (FOM)".
(1) OJ No. 146, 6-6-1987, P66.
(2) OJ No. 20, 25-1-1989, P.33.
(3) OJ No. 123, 19-5-1993, P34.
num: 2
paragraphs: The apparatus shall be equipped with a probe of 6 millimetres diameter containing a photodiode of the Siemens SFH 950/960 type and having an operating distance of between 5 and 105 millimetres. The results of the measurements shall be converted into estimated lean meat content by means of a computer.
num: 3
paragraphs: The lean meat content of the carcase shall be calculated according to the following formula:
= 53,25 - 1,2398x1+ 0,0139x2 + 0,3145x3
where
= the estimated percentage of lean meat in the carcase,
x1 = the thickness of backfat (including rind) in millimetres, measured 6 centimetres off the midline of the split carcase between the third and fourth last ribs,
x2 = x12,
x3 = the thickness of muscle in millimetres, measured at the same time and in the same place as x1.
This formula shall be valid for carcases weighing between 40 and 100 kilograms'.
PART 2
HENNESSY GRADING PROBE (HGP 2)
num: 1
paragraphs: Grading of pig carcases is carried out by means of the apparatus termed "Hennessy Grading Probe (HGP)".
num: 2
paragraphs: The apparatus shall be equipped with a probe of 5,95 millimetres diameter (and of 6,3 millimetres at the blade on 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 transformed in terms of estimated lean meat content by means of the HGP 2 itself as well as a computer linked to it.
num: 3
paragraphs: The lean meat content of the carcase shall be calculated according to the following formula:
= 56,96 — 1,4976x1 + 0,0233x2 + 0,2714x3
where
= the estimated percentage of lean meat in the carcase,
x1 = the thickness of backfat (including rind) in millimetres, measured 6 centimetres off the midline of the split carcase between the third and forth last ribs,
x2 = x12,
x3 = the thickness of muscle in millimetres, measured at the same time and in the same place as x1.
This formula shall be valid for carcases weighing between 40 and 100 kilograms'.
PART 3
INTROSCOPE/MIDLINE
num: 1
paragraphs: Grading of pig carcases is carried out by means of the method termed "introscope/midline".
num: 2
paragraphs: The Introscope shall be equipped with a hexagonal shaped probe of a maximum width of 12 millimetres (and of 19 millimetres at the blade on top of the probe) containing a viewing window and light source, a sliding barrel calibrated in millimetres and having an operating distance of between 8 and 50 millimetres.
num: 3
paragraphs: The lean meat content of the carcase shall be calculated according to the following formula:
= 68,84 - 0,7995x1 + 0,0092x2 - 0,2728x3
where
= the estimated percentage of lean meat in the carcase,
x1 = the thickness of back fat (including rind) in millimetres, measured 6 centimetres off the midline of the split carcase between the third and fourth last ribs,
x2 = x12,
x3 = the minimum thickness of backfat (including rind) in millimetres, measured on the midline of the split carcase covering the lumbar muscle (M. glutaeus medius).
This formula shall be valid for carcases weighing between 40 and 100 kilograms.".
