To determine the average tenderness and sensory ratings of beef subprimal cuts sold in retail cases across United States, were purchased through typical outlets 14 metropolitan cities transported to Texas A&M University for Warner-Bratzler shear analysis. The overall mean force all was 3.65 kg, values chuck, rib, loin, round 3.72, 3.36, 3.17, 4.31 respectively. No difference (P > .05) detected among from rib. Mean palatability top loin steaks similar those rib cuts. Top sirloin tougher <...
ABSTRACT Top loin steaks from strip loins selected 700 beef carcasses representing seven degrees of marbling (Slightly Abundant through Traces) were randomly assigned to untrained consumers (n = 180 per city) in San Francisco, Philadelphia and Kansas City. Statistical analyses revealed a significant level x city interaction. As decreased Slightly Traces, Francisco City gave consistently high ratings that only slightly reduced as was decreased. Consumers rated with the same those other...
The National Beef Quality Audit–2005 assessed the current status of quality and consistency US fed steers heifers. Hide colors or breed type were black (56.3%), red (18.6%), Holstein (7.9%), gray (6.0%), yellow (4.9%), brown (3.0%), white (2.3%), brindle (1.0%). Identification method frequency lot visual tags (63.2%), individual (38.7%), metal-clip (11.8%), electronic (3.5%), bar-coded (0.3%), by other means (2.5%), without identification (9.7%). Brand frequencies no (61.3%), 1 (35.1%), 2...
Fifty-six retail stores representing 15 chains and 14 foodservice facilities in eight U.S. cities were sampled to determine the tenderness of beef steaks at levels based on Warner-Bratzler shear (WBS) values consumer evaluation panels. Retail panels conducted five universities. Each steak was evaluated using 10-point scales. Steaks divided into following quality groups for statistical analysis: Prime, Top Choice, Select, Lean or No Roll. Quality group had no effect WBS clod, chuck roll, top...
The National Beef Quality Audit-1995 was conducted to evaluate the progress of beef industry since time Audit-1991 in improving quality and consistency beef. Nine plants were assigned for auditing Colorado State University, Oklahoma Texas A&M University. Personnel from each institution visited three their nine twice, once spring/summer fall/winter. Data collected on 50% lot slaughter floor 10% cooler during a single day's production (one or two shifts, as appropriate). Of cattle audited...
The National Beef Quality Audit-2000 was conducted to assess the current status ofthe quality and consistency of U.S. fed steers heifers. Between May November 2000, survey teams assessed hide condition (n = 43,415 cattle for color, brands, mud/manure), bruises 43,595 carcasses), offal carcass condemnation 8,588 cattle), yield information 9,396 carcasses) in 30 beef packing plants. Hide colors were black (45.1%), red (31.0%), yellow (8.0%), Holstein (5.7%), gray (4.0%), white (3.2%), brown...
The tenderness and palatability of retail food service beef steaks from across the United States (12 cities for retail, 5 service) were evaluated using Warner-Bratzler shear (WBS) consumer sensory panels. Subprimal postfabrication storage or aging times at establishments averaged 20.5 d with a range 1 to 358 d, whereas level revealed an average time 28.1 9 67 d. Approximately 64% labeled packer/processor store brand. For top blade had among lowest (P < 0.05) WBS values, round greatest...
The 2011 National Beef Quality Audit (NBQA-2011) assessed the current status of quality and consistency fed steers heifers. carcasses (n = 9,802), representing approximately 10% each production lot in 28 beef processing facilities, were selected randomly for survey. Carcass evaluation cooler assessment this study revealed following traits frequencies: sex classes steer (63.5%), heifer (36.4%), cow (0.1%), bullock (0.03%); dark cutters (3.2%); blood splash (0.3%); yellow fat (0.1%); calloused...
The National Beef Quality Audit (NBQA)-2016 used in-plant cooler assessments to benchmark the current status of fed steer and heifer beef industry in United States. In-plant ( = 9,106 carcasses) were conducted at 30 facilities, where approximately 10% a single day's production evaluated for USDA quality grade (QG) yield (YG) factors. Frequencies traits 66.5% 33.4% sex classes 82.9% native, 15.9% dairy-type, 1.2% estimated breed types. Mean YG factors 1.42 cm adjusted fat thickness, 89.5 LM...
Beef retail steaks from establishments across 11 US cities and beef foodservice in 6 were evaluated using Warner-Bratzler shear (WBS) force consumer sensory panels. The average post-fabrication aging time of at was 25.9 d with a range to 102 d, those averaged 31.5 3 91 d. the lowest WBS value (P < 0.05) boneless top loin, compared round steaks, which had higher value. For sector, loin ribeye values, whereas sirloin represented highest values. blade received among ratings 0.05), bottom for...
Abstract The National Beef Quality Audit-2016 (NBQA-2016) was conducted to assess current transportation, mobility, and quality characteristics of U.S. fed steers heifers. Data were collected at 17 beef processing facilities between March November 2016. About 8,000 live cattle evaluated for transportation about 25,000 carcasses on the slaughter floor. Cattle in transit facility a mean duration 2.7 h from distance 218.5 km using trailers with dimensions ranging 17.84 m2 59.09 m2. Area...
Meat-type (Boer × Spanish and Spanish) goats from two feeding regimens (feedlot range) were slaughtered live carcass weights obtained. At 24 h after death, various yield quality measurements collected. One side each was fabricated into major wholesale cuts for dissection components. Feedlot had heavier (P < .05) carcasses that yielded more dissectible fat lean less bone, as a percentage of weight, than did the range goats. In feedlot environment, Boer greater weights, actual adjusted...
To assess the then-current population of fed beef cattle for quality defects, federally inspected steer and heifer slaughter in 28 packing plants was surveyed during a 3-mo period (October to December 1991). Data were collected over course 1 d production at chain speed. Carcasses selected randomly include 50 10% each lot on floor cooler, respectively. Slaughter defects evaluated brand location size, degree bruising, grubs injection sites, condemnation offal, presence mud horns. USDA grade...
The National Beef Quality Audit-2011 (NBQA-2011) was conducted to assess targeted characteristics on the harvest floor that affect quality and value of cattle, carcasses, byproducts. Survey teams evaluated approximately 18,000 cattle/carcasses between May November 2011 in 8 beef processing facilities. Cattle identification methods were lot visual tags (85.7%), individual (50.6%), electronic (20.1%), metal-clip (15.7%), other (5.3%), none (2.5%), wattles (0.5%). Hide colors or breed types...
Abstract The National Beef Quality Audit (NBQA)-2022 serves as a benchmark of the current market cow and bull sectors U.S. beef industry allows comparison to previous audits method monitoring progress. From September 2021 through May 2022, livestock trailers (n = 125), live animals 5,430), post-slaughter hide-on 6,674) were surveyed at 20 commercial processing facilities across Cattle transported in variety trailer types for an average distance 490.6 km mean transport time 6.3 h. During...
This survey consisted of data collected from 23 beef harvest plants to document transportation procedures, management practices, and health assessments market dairy cows bulls (about n ≅ 7,000 animals). Gooseneck/bumper-pulled trailers were used more often transport cattle than whereas tractor-trailers cattle. All loads (n = 103) met the American Meat Institute Foundation guidelines for spacing. Loads where 3% slipped during unloading observed in 27.3% 29.0% loads. Beef had numerically...
Four groups of goats, Boer x Spanish, straightbred Spanish Angora, and Angora were slaughtered at a constant age according to accepted industry procedures. At 24 h postmortem, various carcass yield quality measurements taken. 48 one side from each was fabricated into major wholesale cuts for dissection percentage lean, bone, fat. Rib chops the opposite fabricated, packaged, displayed in retail case. Trained panelists evaluated rib over 4 d display lean color, surface discoloration, overall...
