The objective of the current study was to evaluate effects aging on myoglobin chemistry dark-cutting beef. Ten USDA Choice (mean pH = 5.6; normal beef) and 10 no-roll dark cutter 6.4) strip loins were obtained from a commercial packing plant within 3 d harvest. Loins cut into 4 sections, vacuum packaged, randomly assigned 0-, 21-, 42-, 62-d at 2°C in dark. Following aging, loin sections 2.5-cm-thick steaks used determine bloom development, oxygen consumption (OC), metmyoglobin reducing...
Broilers are commonly exposed to coccidiosis infections, and the use of dietary strategies reduce losses in growth performance has practical implications for poultry industry. Methionine (Met) is typically first limiting amino acid broilers involved metabolic immunological pathways; however, literature conflicting on how Met requirements affected by environmental stressors. Our objective was assess requirement changes during based results performance, carcass traits, health outcomes. Two...
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...
The objective was to characterize the relationship between fresh loin quality with belly or and cured ham quality. Pigs raised in 8 barns representing 2 seasons [cold (n = 4,290) hot 3,394)] production focuses [lean 3,627) 4,057)] were used. Carcass characteristics other meat data collected on 7,684 carcasses. All of carcasses evaluated for HCW, LM depth, tenth rib fat leg (ham primal) weight, instrumental color gluteus medius profundus face, subjective Instrumental ultimate pH (≥ 22 h...
Abstract Supplemental methionine (Met) is widely used within the swine industry; however, data are limited regarding effect of Met sources on carcass cutability and meat quality. The objective was to determine effects L-Met (LM, 99%), DL-Met (DLM, or calcium salt hydroxyl analog (MHA, 84%) in finishing pig diets characteristics At 9 weeks age, pigs (N = 240) were allocated 60 single-sex pens for a four-phase trial that lasted 104 d. Pigs fed common grower diet until day 56 where randomly...
The objective was to determine the predictive abilities of HCW for loin, ham, and belly quality 7,684 pigs with carcass weights ranging from 53.2 129.6 kg. Carcass composition, subjective loin quality, ham face color were targeted on all carcasses, whereas in-plant instrumental assessed 52.0 47.5% respectively. Loin chop slice shear force (SSF), cured adipose iodine value (IV) evaluated at least 10% population. slope regression lines coefficients determination between traits computed using...
In livestock science and meat science, muscle fiber characteristics have been evaluated based on a cross-sectional area (CSA) of fiber. However, is not planar but cylindrical. Thus, volume volume-based were in this study. addition, their relationships to pork loin quality was assessed compared with that CSA-based characteristics. Muscle type IIB underestimated by evaluations 1.6 times size 2.6 relative composition. The pennation angle, which ranged from 48.00° 83.33°, determined the real CSA...
The objective was to test inherent cooking rate differences on tenderness values of boneless pork chops when exogenous factors known influence were controlled. Temperature and elapsed time monitored during for all chops. Cooking calculated as the change in °C per minute time. Warner-Bratzler shear force (WBSF) measured cooked either 63 or 71 °C. Slopes regression lines coefficients determination between both degrees doneness (DoD) calculated. Shear decreased increased regardless DoD (p ≤...
Abstract The National Beef Quality Audit – 2022 serves as a benchmark of the current fed steer and heifer population U.S. beef industry allows comparison to previous audits method monitoring progress. In-plant cooler assessments collections carcass data took place from July 2021 November 2022. During in-plant evaluations, 10% 1-d production was surveyed for quality yield indicating characteristics carcasses (n = 9,746 carcasses). Distributions sex classes among sampled were (65.0%) (35.0%),...
Abstract The objective of this research was to determine the effects mid-gestational maternal inflammation on performance, carcass characteristics, and meat quality offspring. Pregnant gilts were administered either lipopolysaccharide (LPS; n = 7) or saline (CON, from days 70 84 gestation. Gilts assigned LPS treatment an intravenous injection reconstituted every other day with a beginning dose 10 μg LPS/kg body weight subsequent doses increasing by 12%, while CON received injections...
Today, the United States exports 2.2 million tons of pork and products annually, representing just over 26% U.S. production. In order to meet specific demands a growing export market, quality carcass characteristics are now integrated into breeding objectives. Color marbling 2 loin traits that influence consumer acceptability while correlations between early aged ventral have been established, it is unclear if those differ production objectives (meat vs. lean growth). Therefore, objective...
Feeding growing-finishing pigs supplemental fat is a common practice in the swine industry and can result improved feed efficiency reduced intake; however, dietary lipids also play key role determining pork composition. The objectives of current study were to evaluate effects feeding graded levels high oleic soybean oil (HOSO) on growth performance carcass characteristics. A total 288 raised two separate blocks (144 each) assigned one four diets containing either 25% dried distiller's grains...
Rapid assessment of pork quality by packers necessitates using early postmortem (∼1 d) traits as an indication aged (∼14 d). Efforts have been made to develop a grading system based on color and marbling the ventral side boneless loins. In order for this be successful, there must correlation between observed same consumers after aging. However, strength direction those correlations are unclear. It is also unknown if differ barrows (B) gilts (G). Therefore, objectives were determine loin...
The objective was to characterize ham and loin quality of carcasses ranging from 78 145 kg (average ∼119 kg). Hot carcass weight (HCW), back fat depth, depth measured on 666 carcasses. Loin pH, instrumental visual color iodine value clear plate (all 3 layers) approximately 90% the population. Quality measurements ham, 14 d aged chop, chop shear force (SSF) were evaluated 30% Myosin heavy chain fiber type determination completed 49 Slopes regression lines coefficients between HCW traits...
The objective of this study was to evaluate the effects increased pork hot carcass weight on loin quality and palatability top chops. Pork loins (N = 200) were collected from 4 different groups: A light (LT; less than 111.8 kg), medium-light (MLT; 119.1 medium-heavy (MHVY; 124.4), a heavyweight group (HVY; 124.4 greater). Following fabrication, chops assigned fat moisture analysis, Warner-Bratzler shear force (WBSF), consumer sensory panels, or trained panels. Chops HVY rated as more (P <...
The objective was: 1) to characterize the effect of marketing group on fresh and cured ham quality, 2) determine which traits correlated quality traits. Pigs raised in 8 barns representing 2 seasons (hot cold) production focuses (lean quality) were used. Three groups marketed from each barn. A total 7,684 carcasses used for data collection at abattoir. Every tenth carcass was noted as a select in-depth analyses. Leg primal weight instrumental color measured 100% population. On 10%...

Supplementation of vitamin E improves beef colour stability by minimizing lipid oxidation-induced myoglobin oxidation. Mitochondria affect redox stability, and dietary influences mitochondrial functionality in skeletal muscles. Nonetheless, the influence on proteome muscles has yet to be investigated. Therefore, objective this study was examine effect post-mortem longissimus lumborum (LL) muscle. Beef LL muscle samples (24 hours post-mortem) were obtained from carcasses nine (n = 9) E-fed...
