The estimated accuracy of the EU reference dissection method for pig carcass classification.

Area of Science:

• Animal Science
• Agricultural Economics
• Food Science

Background:

• Accurate determination of lean meat percentage (LMP) is crucial for the meat industry.
• The EU-reference dissection method is a standardized approach for assessing carcass composition.
• Understanding factors affecting the accuracy of this method is essential for consistent results.

Purpose of the Study:

• To evaluate the accuracy of the EU-reference dissection method.
• To identify and quantify factors influencing the accuracy of the method.
• To assess the repeatability and reproducibility of the dissection process.

Main Methods:

• The study involved 128 pig carcasses dissected by 8 butchers across 4 European countries.
• Carcasses were selected based on weight, fat class, and sex.
• Accuracy was measured using repeatability and reproducibility standard deviations and reliability.

Main Results:

• The EU-reference dissection method showed high accuracy, with a reliability of 0.87.
• Repeatability and reproducibility standard deviations were 0.87 and 1.10, respectively.
• Significant effects of butcher and carcass jointing on lean meat percentage estimation were observed.

Conclusions:

• The EU-reference dissection method is a highly accurate technique for assessing lean meat percentage.
• Butcher experience and the jointing process are critical factors impacting the accuracy of the method.
• Further standardization or training may be beneficial to minimize variability in lean meat percentage estimation.
