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...
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...
We hypothesized that combining sensory flavor attributes, volatile aroma compounds (VAC), and fatty acid composition would better separate beef quality grades than alone. Select, Choice, Prime, Grass-fed ribeye rolls (n = 6 per group) were purchased from a local distributor, so production conditions or cattle type unknown. Select cooked steaks ranked lowest for Beef Flavor, Bloody/Serumy, Brown/Roasted, Umami (P ≤ 0.048). Prime had greater values other steak types the VAC 2-methyl-butanal,...
A total of 32 select line (SL) and control (CL) Duroc pigs were used in two trials to determine the effect dietary amino acid contents during grower (G) phase selection for lean growth efficiency on performance, carcass traits, meat quality. In each trial, weighing 20 kg assigned 16 pens with gilts or castrated males per pen, randomly within genetic corn-soybean meal G diets formulated contain 5.0, 7.0, 9.0, 11.0 g lysine/kg. After 50 kg, all fed common finisher 1 (F1) 2 (F2) diets. Pigs...
The objective of this experiment was to determine the effect different doses vitamin D3 (VITD) on beef feedlot performance, plasma and muscle Ca2+, tissue residues, improvement Warner-Bratzler shear force (WBS) panel tenderness. A total 167 steers were fed one six levels VITD. VITD treatments (28 steers/treatment) 0, 0.5 x 10(6), 1 2.5 5 7.5 10(6) IU/steer daily nine consecutive days before slaughter. Feedlot performance Ca2+ measured during last 21 feed. strip loin top round steaks at 7,...
Boneless strip loin subprimals (n = 24) were fabricated from 12 USDA Standard yield grade 2 carcasses at a commercial beef processing facility and processed 48 h postmortem to determine the effect of injection 200 or 250 mM calcium chloride (CaCl2) solution 5% (wt/wt) on quality traits. One-third subprimal served as control; remaining portion was injected with either CaCl2 (wt/wt). The concentration treatment randomly assigned loins right left side carcass. After 7 14 d storage degrees C,...
Duroc-cross pigs (n = 25) were assigned to one of three experimental finishing diets containing 0 (control), 40,000 (40), or 80,000 (80) IU supplemental vitamin D3/kg feed (as-fed basis)to test the effects D3 on pork quality traits. Experimental fed for 44 51 d before slaughter, and days blocked in design. A trend existed receiving highest concentration supplementation have a lower (P 0.08) ADG (0.77 kg/d) compared with either 40-diet (0.88 control (0.92 kg/d). Diet did not > 0.10) affect...
A boneless beef strip loin (IMPS #180) was fabricated from each of 320 carcasses to study the effects slaughter plant location, quality grade, fat thickness, and aging time on tenderness palatability. Carcasses were selected for thickness (< .5 cm or ≥ thickness) USDA grade (Select Low Choice) two facilities (IBP, Inc., Garden City, KS Excel Plainview, TX), strips aged either 7 14 d. Aging steaks d improved all sensory traits Warner-Bratzler shear (WBS) values regardless other main (P <...
ABSTRACT: Twenty‐six crossbred steers were finished either on ryegrass ( Lolium multiflorum Lam.) forage (FOR, n = 13) or a primarily grain diet containing 85% corn, 7.5% cotton‐seed hulls, and vitamin/mineral/urea supplement (GRAIN, to determine the consumer acceptance of forage‐ grain‐finished beef in 3 southeastern states. Shear force values not affected by finishing treatment P 0.62), both total heat‐labile collagen content means FOR GRAIN steaks similar 0.88 0.14, respectively). Ribeye...
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.
