The objective of this study was to benchmark carcasses and muscles from commercially identified fed (animals that were perceived to have been fed an increased plane of nutrition before slaughter) and nonfed cull beef and dairy cows and A-maturity, USDA Select steers, so that the muscles could be identified from cull cow carcasses that may be used to fill a void of intermediately priced beef ste...

After the Fukushima No. 1 Nuclear Power Plant accident, high levels of radioactive cesium were detected in beef. Many prefectural governments decided to conduct blanket tests on meat from local beef cattle to prevent distribution of beef contaminated with radioactive cesium exceeding the provisional regulation value. In some cases, different concentrations of radioactive cesium were found in di...

ABSTRACT: Video image analysis (VIA) images from grain-fi nished beef carcasses [n = 211; of which 63 did not receive zilpaterol hydrochloride (ZIL) and 148 received ZIL before harvest] were analyzed for indicators of muscle and fat to illustrate the ability to improve methodology to predict saleable meat yield of cattle fed and not fed ZIL. Carcasses were processed in large commercial beef pro...

there has been considerable inconsistency regarding the potential relationship between dyslipidemia and bone metabolism. the inflammatory stimulation through the receptor activator of the nuclear factor kappa-b ligand (rankl)/ receptor activator of the nuclear factor kappa-b (rank)/ osteoprotegerin (opg) pathway could be the infrastructural mechanism for hypercholesterolemia-induced bone loss. ...

Effects of dietary fats consisting of different fatty acids on lipoprotein lipase activities in the interscapular brown adipose tissue, heart, and soleus muscle, and on body fat accumulation were studied in rats. Sprague-Dawley male rats were meal-fed an isoenergetic diet based on either beef tallow or safflower oil for 8 weeks. Lipoprotein lipase activities in the interscapular brown adipose t...

Fifty foodservice purveying companies were sampled in 12 U.S. cities evenly distributed across six geographical regions. Beef whole muscle cuts (WMC) and portion control items (PCI) from the primal rib and loin were evaluated for surface fat levels. Fat thicknesses were measured on WMC before and after fabrication, whereas additional PCI were measured for fat trim levels before distribution. Th...

The effects of dietary fats , consisting of different fatty acids, on body fat accumulation and uncoupling protein (UCP) in interscapular brown adipose tissue were studied in rats. Metabolisable energy in experimental diets based on safflower oil, soybean oil or beef tallow was measured strictly (experiment 1). Male Wistar rats were then meal-fed an isoenergetic diet for 8 weeks (experiment 2)....

Calves weaned on cow­calf operations throughout Arkansas even­ tually move on to stocker, feedlot and packer operations. Wide variations in carcass uniformity and consistency exist among these calves. Potential carcass problems can include inappro­ priate carcass size and weight, i nadequate tenderness, insufficient intramuscular fat (marbling) and excess external fat cover. Many of these quali...

There are three economically important traits under the CUlTent U. S. Beef Grading System: the distribution and amount of intramuscular fat (or marbling), the subcutaneous fat thickness, and the ribeye muscle size. These traits are also major factors used in evaluating body composition for genetic improvement. The marbling scores are visually graded by certified inspectors under the current USD...

Introduction: The future success of the beef industry will be largely determined by our ability to meet consumer demands. Consumers want beef to be safe, consistently tender, palatable, free of outside fat, easy to prepare, and reasonably priced compared to other proteins. The dramatic increase in the number of cattle marketed through grid pricing structures is an example of the beef industry r...
