Division 2.3: Where partial dissection is carried out, the prediction of the reference lean meat percentage (YPD) is based on the dissection of the four major cuts (shoulder, loin, ham and belly) plus the weight of the tenderloin. The partial dissection lean meat percentage is calculated as follows: - Commission Delegated Regulation (EU) 2017/1182 of 20 April 2017 supplementing Regulation (EU) No 1308/2013 of the European Parliament and of the Council as regards the Union scales for the classification of beef, pig and sheep carcasses and as regards the reporting of market prices of certain categories of carcasses and live animals

Y_{PD} = \frac{100 \times (weight of tender loin + weight of lean meat in the shoulder, loin, ham and belly)}{weight of tender loin + weight of the shoulder, loin, ham and belly before dissection}

The weight of the lean in the four major cuts (shoulder, loin, ham and belly) shall be calculated by subtracting the total weight of the non-lean elements of the four cuts from the total weight of the cuts before dissection.

The bias between total and partial dissection is corrected based on a subsample with total dissection.
