This study was performed to determine the influence of pig breed and gender on the ultimate pH and physicochemical properties of pork. The correlations between pH and pork quality traits directly related to carcass grade, and consumer's preference were also evaluated. The pH and meat grading scores for cold carcasses of 215 purebred pigs (Duroc, Landrace, and Yorkshire) from four different farm...

The simple method of evaluating highly marbled beef was examined by image analysis. The images of the cross section at the 6 to 7th rib were obtained from 82 carcasses of Wagyu cattle. By using an overall trace method, the surrounding edges of the longissimus thoracis and three muscles were traced automatically and manually with image analysis. In a spot method, 3 to 5 locations (2.5 or 3.0 cm ...

Crossbred yearling steers (n = 1000; 755 ± 23 lb) were utilized to evaluate effects of sorting and feeding zilpaterol hydrochloride (Zilmax®) on feedlot performance, carcass characteristics, and economics. Treatments were: unsorted negative control (–CON); unsorted Zilmax fed positive control (+CON); and three treatments where the heaviest 20% of steers within the pen were identified at beginni...

In this study two separate sets of data were used to develop prediction equations for Marbling Scores (MS) from actual percentage intramuscular fat. All regression parameters were significantly (P<.01) different from zero. Model-I explained only 49% of the variation in MS as compared with 83% for modelII. When these equations were validated on an independent data set, the correlations between t...

Despite several issues in relation to human health, beef is still a most popular meat product among large section of society due to the presence of high quality protein and other nutrients. The current paper reviews numerous studies that provide nutritional profiles and health implications of high marbled beef consumption. In relation to lipid content of beef, intramuscular fat contains high le...
