Evaluation of ultrasound for prediction of carcass fat thickness and longissimus muscle area in feedlot steers
Article Abstract:
Ultrasonic measurements of the fat thickness and longissimus muscle area were made on 452 one-year old steers to evaluate ultrasound scanning's effectiveness in predicting meat quality. The readings were then compared to actual measurements made after the steers were slaughtered. Results indicated that ultrasound scanning is an efficient tool in estimating the thickness of subcutaneous fat, but is a poor predictor of muscle area. Estimating muscle area based on the animal's live weight proved to be a more precise predictor of leanness.

Effects of days fed, carcass grade traits, and subcutaneous fat removal on postmortem muscle characteristics and beef palatability
Article Abstract:
Forty-eight steers were given high concentrate finishing diet, fat-trimmed, slaughtered and evaluated for performance traits, carcass characteristics, palatability attributes and postmortem muscle features. Reports given by experienced evaluators show that there was an improvement on tenderness with high-concentrate diet, early post-mortem temperature, increased fat thickness, and carcass weight. Marbling score was the nearest correlate to tenderness and is influenced by serial slaughter technique, uniform cattle type and breed type.

Effects of steam-flaked sorghum grain or corn and supplemental fat on feedlot performance, carcass traits, longissimus composition, and sensory properties of steers
Article Abstract:
Five groups of crossbred steers were fed with steam-flaked sorghum grain, steam-flaked corn, yellow grease and supplemental fat for 100 days. Results showed that grain type does not affect daily gain, feed consumption and gain efficiency in steers. The energy value of sorghum grain can be raised to that of corn by steam-flaking but degree of processing, berry size, and bulk density can influence energy utilization in sorghum. It further shows that beef quality of cattle fed from sorghum equals that of corn.
