Pig carcass classification in the 65-190 kilogram range using the Danish fat-o-meat'er

Area of Science:

• Animal Science
• Meat Science
• Agricultural Engineering

Background:

• Accurate assessment of pork carcass composition is crucial for the meat industry.
• Traditional methods for determining lean content can be time-consuming and destructive.
• Standardized carcass evaluation methods are essential for fair trade and quality control.

Purpose of the Study:

• To develop and validate a partial dissection formula for predicting meat content in Italian pig carcasses.
• To establish a more efficient method for estimating lean yield in pork.
• To correlate external carcass measurements with actual meat, fat, and bone content.

Main Methods:

• Selection of 200 pig carcasses representing a wide range of weights and lean content from the Italian market.
• Measurement of fat thickness and muscle depth at various points on the carcass (e.g., last rib, lumbar vertebrae, dorsal midline).
• Partial or total dissection of selected carcasses to determine meat, fat, and bone content, and to develop/verify a predictive formula.

Main Results:

• A partial dissection formula was developed based on carcass measurements.
• The formula was tested on a subset of carcasses, showing its utility in estimating meat content.
• The study established relationships between external measurements and internal carcass composition.

Conclusions:

• The developed partial dissection formula provides a reliable and efficient method for estimating meat content in pig carcasses.
• This method can aid in optimizing pork carcass grading and value assessment.
• Further validation may enhance the formula's applicability across different pig populations and markets.
