Article Synopsis
- - The study aimed to create and validate calibration models for the Frontmatec Q-FOM™ Beef grading camera based on rib eye traits found in Australian carcasses, using data from 12 commercial processing facilities.
- - The Q-FOM™ showed strong predictive performance for continuous traits like eye muscle area, marbling, and intramuscular fat percentage, achieving high accuracy and precision metrics (R values up to 0.95).
- - For categorical traits such as marbling and meat color, the camera achieved over 60% prediction accuracy and demonstrated excellent repeatability, with 95% of valuations falling within one class of expert graders.
This study aims to describe the meat quality of young Holstein (HOL) beef-on-dairy heifers and bulls sired by Angus (ANG, n = 109), Charolais (CHA, n = 101) and Danish Blue (DBL, n = 127), and to investigate the performance of the handheld vision-based Q-FOM™ Beef camera in predicting the intramuscular fat concentration (IMF%) in M. longissimus thoracis from carcasses quartered at the 5th-6th thoracic vertebra. The results showed significant differences between crossbreeds and sexes on carcass characteristics and meat quality.

The position of the shoulder depends on the target spacing and is directly connected to the finite formation length of a low-energy photon emitted by an ultrarelativistic electron. With the present setup it is possible to control the separation of the foils on a μm scale and hence measure interference effects caused by the macroscopic dimensions of the formation length.
