USMARC Beef Carcass Instrument Grading Systems
The USMARC beef carcass image analysis system objectively evaluates beef carcass grade factors including marbling score, adjusted preliminary yield grade, and ribeye area (Figure 1). This image analysis system can assess USDA yield grade more precisely and accurately than can be achieved by USDA graders. Furthermore, use of this image analysis system will allow for creation of additional yield ...
متن کاملThe relationship between ultrasound measurements and carcass fat thickness and longissimus muscle area in beef cattle.
Five hundred thirty-four steers were evaluated over a 2-yr period to determine the accuracy of ultrasonic estimates of carcass 12th-rib fat thickness (CFAT) and longissimus muscle area (CLMA). Within 5 d before slaughter, steers were ultrasonically measured for 12th-rib fat thickness (UFAT) and longissimus muscle area (ULMA) using an Aloka 500V real-time ultrasound machine equipped with a 17.2-...
متن کاملEvaluation of ultrasonic estimates of carcass fat thickness and longissimus muscle area in beef cattle.
Yearling crossbred feedlot steers (n = 495) and heifers (n = 151) were ultrasonically measured at the 12-13th rib interface 24 h before slaughter to evaluate the accuracy of ultrasonic measurements of fat thickness (BFU) and longissimus muscle area (LMAU) for prediction of actual carcass measures. Isonification was with an Aloka 210DX ultrasound unit equipped with a 12.5-cm, 3.0-MHz, linear arr...

متن کاملUse of expected progeny differences for marbling in beef: II. Carcass and palatability traits.
A 2-yr study was conducted to determine the effect of EPD for marbling on marbling score, palatability traits, and carcass fatness in beef. Steer (n = 122) and heifer (n = 123) carcasses were obtained by mating Angus bulls having a high ( > .4) or low ( < -.16) EPD for marbling to MARC II cows (1/4 Angus, 1/4 Hereford, 1/4 Simmental, and 1/4 Gelbvieh). Carcass traits, composition of primals, qu...
