ANNEXU.K.Methods for grading pig carcases in the Czech Republic

[F1PART 6 U.K. Needle IS-D-15

1. Grading of pig carcasses shall be carried out by use of the method termed Needle IS-D-15 . U.K.

2. The grading apparatus IS-D-15 is a device using a sharp needle probe which is inserted into a given place of the carcass; the insertion depth is about 140 mm. A special engineered optical set is located behind the needle that by the means of an optical channel enlightens the surrounding tissue or area and scans the amount of reflected light energy with the defined wavelength. The terminal is also equipped with a precise contactless measuring device which determines the current insertion depth with 46 micrometer precision. U.K.

[F23. The lean meat content of the carcass shall be calculated according to the following formula: U.K.

where:

Ŷ

the estimated percentage of lean meat in the carcass,

S

the thickness of back-fat (including rind) in millimetres, measured at 7,5 centimetres off the midline of the carcass between the second and third last ribs,

M

the thickness of muscle in millimetres, measured at the same time and in the same place as S.

This formula shall be valid for carcasses weighing between 60 and 120 kilograms.] ]
