The economic efficiency of dual purpose cattle is influenced by a large number of traits which may be classified in groups of dairy, beef and functional traits. The combination of estimated breeding values for single traits in a total merit index, as long practised in some Scandinavian countries, is currently being implemented in a number of Central European states. Economic values for populati...

by Ting Jiang, M.S. Washington State University December 2008 Chair: Mark L. Nelson Fatty acids in meat have obtained a lot of attention from both scientists and consumers because fatty acids are demonstrated to be closely related with human health and meat is an important food source, especially, for developed countries. Beef has been the most consumed red meat in the US and the argument exist...

Some nutrient data for beef sausages in Australia's food composition table, NUTTAB 2010, is over 25 years old and may no longer reflect the composition of this popular food. To update this, 41 retail samples of fresh beef sausages were purchased in Melbourne, Australia, in May 2015. Each purchase was analysed, uncooked, for moisture, protein and fat. Sausages were then grouped by fat content in...

The purpose of this study was to determine effects of feeding canola and soybean products as protein supplements on fatty acid composition of adipose tissue and muscle of slaughter bulls and steers and on fatty acid composition of kidney and liver total lipids of bulls. Products included canola meal (CM), extruded canola (EC, full-fat), ground canola (GC, full-fat), soybean meal (SBM), and extr...

DNA methylation is essential for adipose deposition in mammals. We screened SNPs of the bovine DNA methyltransferase 3b (DNMT3b) gene in Snow Dragon beef, a commercial beef cattle population in China. Nine SNPs were found in the population and three of six novel SNPs were chosen for genotyping and analyzing a possible association with 16 meat quality traits. The frequencies of the alleles...

Improvement of USDA Select grade beef is essential for consumer acceptance of leaner beef. Seventy-two large- and medium-framed steer calves of mixed breeding were used in two experiments to evaluate feedlot performance, carcass composition, and beef palatability. Interactions of dietary energy level (corn concentrate or corn silage), breed type (Angus or Simmental), carcass electrical stimulat...

Beef marbling is the most important indicator of beef quality grading via measuring the abundance of intramuscular fat (IMF) in rib-eye muscle. A beef marbling grading method was developed herein based on image processing and support vector machine (SVM). 123 images of beef rib eye steak were acquired for manual evaluation and image processing. After the marbling, scores were labelled to each i...

Additive genetic Angus-Brahman differences, heterosis effects, and least squares means for six carcass and six meat palatability traits were estimated using data from 1367 steers from the Angus-Brahman multibreed herd of the University of Florida collected from 1989 to 2009. Brahman carcasses had higher dressing percent (P<0.0001), lower marbling (P<0.0001), smaller ribeye area (P<0.0001), and ...

This research aimed to use mustard flour as meat binder in processing of beef burgers instead of soybean flour (SF). Effect of addition mustard flour from two mustard varieties, yellow (Sinapis alba) (YMF) or brown (Brassica juncea) (BMF) mustard seed flour at different levels (3 and 6%) on the quality characteristics of beef burger patties was studied. The incorporation of mustard flour as a b...

BACKGROUND Evidence indicates that different types of fat have different effects on the postprandial plasma triacylglycerol response. Therefore, the type of fat may influence the appearance of beta-carotene in postprandial triacylglycerol-rich lipoproteins, which is used as an indicator of intestinal beta-carotene absorption. OBJECTIVE We compared in female subjects the appearance of beta-car...
