  abstract: The National Beef Quality Audit is a recurring study that allows researchers to establish benchmarks the beef industry in the United States through assessments of cattle/carcass attributes through all stages of beef processing. The 2021 NBQA in-plant cooler assessments and instrument grading data collections took place from July 2021 to September 2022. During in-plant evaluations (n = 8,738 beef carcasses), 10% of one day's production was surveyed for quality and yield indicating characteristics of fed beef carcasses. Distributions of sex class among sampled carcasses were steer (66.5%) and heifer (33.4%), while distributions of breed type were native (86.5%), dairy (12.6%), and Bos indicus (0.9%). Mean values were observed for USDA YG (3.3), overall USDA QG (Choice^19), marbling score (Modest^00), LMA (90.6 cm^2), AFT (1.47 cm), HCW (401.5 kg), and KPH (2.5%). 28.1% of carcasses were identified for use in a USDA certified beef G-Program. Defects, such as dark cutting and blood splash were observed at 1.7% and 0.5%, respectively. Distributions of USDA YG were YG 1 (6.9%), YG 2 (29.7%), YG 3 (40.9%), YG 4 (16.8%), and YG 5 (5.7%). USDA QGs were observed at 7.8% Prime, 70.0% Choice, 15.9% Select, and 6.3% Other. During instrument grading assessments (n = 4,418,768), one week's worth of grade data was collected from 6 large scale beef processors each month from July 2021 to June 2022. The year-long data collected provide a view of the seasonality of the fed beef industry. Mean values were observed for USDA YG (3.3), marbling score (Modest^16), LMA (91.6 cm^2), AFT (1.55 cm), and HCW (400.6 kg). Distributions of USDA YG were YG 1 (7.9%), YG 2 (31.7%), YG 3 (40.0%), YG 4 (17.1%), and YG 5 (3.3%). Distributions of USDA QG were Prime (8.2%), Choice (74.7%), Select (15.8%), and other (1.4%). The highest frequency of carcasses grading Prime occurred on Monday (10.89%). HCW's peaked in the months of December and January and decreased monthly towards June and July. These data …
