Ultrasonic prediction of carcass merit in beef cattle: evaluation of technician effects on ultrasonic estimates of carcass fat thickness and longissimus mucsle area
Article Abstract:
Results of a study indicated that trained and experienced technicians provide accurate and comparable interpretation of ultrasonic data on beef cattle. Two technicians with similar training and experience subjected 36 steers to ultrasonic examination to obtain estimates of carcass fat thickness (FTU) and longissimus muscle area (LMAU). Evaluation of technician's role in dealing with ultrasonic data related to slaughter animals indicated that estimation of FT and LMAU is influenced equally by retrieval and interpretation of images.

Effect of hot-fat trimming on factors associated with the subprimal yield of beef carcasses
Article Abstract:
Consumer demand for leaner beef has prompted beef packers to reduce fat levels on beef subprimals. A study was done to ascertain the effect of hot-fat trimming on factors associated with subprimal yield of beef carcasses. Thirty-two crossbred cattle were trimmed of fat and evaluated. Results show that hot-fat trimming decreases the difference caused by subprimal yield due to excess fat. This produces leaner beef with a higher product value.

Lean color characteristics of bullock and steer beef
Article Abstract:
A study was conducted to compare steer and bullock beef using pH determination, visual, colorimetric and microbiological analysis. Experienced panelists could detect lean color characteristics in beef and bullock but consumers have no purchase preference. There was no significant difference seen in the other tests. This means that bullock beef can pass off as steer beef in retail stores.
