Abstract

Lean Meat Percentage (LMP) is a key index for assessing pork carcass quality as well as determining carcass classification and price. This framework offers to farmers the incentive to achieve the desired organoleptic features; therefore LMP must be measured objectively online, by means of various measuring instruments. The aim of this work was to assess two different methods for predicting the lean meat percentage of pig carcasses in Greece in comparison to the European reference method. For this reason, the same 130 pig carcasses (65 males and 65 females) were measured using 2 prediction devices (Optiscan-TP and Optigrade-MCP) and subsequently were assessed according to European reference method. A formula corresponding to each device was constructed using the ordinary least squares (OLS)method and excluding the same outliers. Calculated RMSEP for all 130 carcasses was 2.46518 for Optiscan-TP and 2.48489 for Optigrade-MCP. It can be concluded that both methods perform entirely according to EU legislation (Commission Regulation (EC) 1249/2008, European Union, 2008), and results obtained are similar regardless of different measurement points and technologies.
