Accomplishments
Objective 1: Improve meat quality, safety, and value at all levels of the supply chain to enhance competitiveness and to evaluate economic impact of these new approaches.
Continued advances in understanding the hydrodynamic pressure process (HDP) and its application to reduce variability in tenderness and improve consumer acceptance of meat have been made. Concerns about the inconsistency in instantaneous improvement in tenderness when using HDP were shown to be of minimal concern. Provided that meat is treated with HDP anytime after 2 days postslaughter, HDP significantly improves meat tenderness. The research implication is that HDP can reduce aging time of retail beef for enhanced tenderness. The economic implication is reduced energy requirements for refrigeration. Examining the synergy of HDP with diacetyl for reducing or eliminating bacteria in ground beef is also encouraging (ARS&VPI).
Research was conducted to investigate the role of the calpain/calpastain system in the development of pork tenderness. Research results indicate that the CAST gene affects the textural integrity of fresh pork. Work was also conducted to investigate the link between the postmortem process and pork quality. This study indicated that the duration of time from stunning to evisceration was positively correlated with loin-chop shear force levels(IA).
On going research investigating the use of image analysis and the Japanese pork fat models as bench marks for measuring pork fat color indicate that the value of U.S. retail pork cuts, as measured by subcutaneous fat samples, failed to meet the criteria for premium Japanese no.1 and no.2 categories. Preliminary work on using image analysis to estimate beef marbling is underway (NV).
Work on refining a prediction system for ruminant animal growth and composition is ongoing in collaboration with AgResearch of New Zealand. The refined model predicts empty body weight and fat content more accurately than the current U.S. NRC or Australian SCA systems (U-C Davis).
Several issues related to consumer preference for beef were investigated by researchers at the Nebraska and Colorado stations. Initial results indicate that consumers preferred wet aged beef to dry aged beef. The study also found consumers are willing to pay for country-of-origin labeling
Recent work has been completed on the topic of traceability and certification for red meat in the U.S. and the U.K.. The study finds that U.S. consumers place greater trust in the public sector relative to the private sector for meat certification. The opposite is true in the U.K. (UT).
Objective 2: Evaluate the impacts of the changing structure of the meat industry including price discovery under alternative pricing systems, trading institutions and methods of delivery.
Preliminary research at South Dakota State University (SDSU) indicates that the rate of return to retained ownership of weaned steer calves is positive and is affected by ranch of origin management practices and health management practices before calves are placed in the feedlot. Retaining ownership is one method of adding value to cow/calf operations. The information value of mandatory price reporting for live cattle relative to voluntary price reporting is being investigated at SDSU. Statistical analysis indicates that the former voluntary price reporting system was providing accurate information to South Dakota producers.
The effect of recent structural changes in the U.S. Agriculture on agricultural markets is investigated using experimental economic methodology. Results indicate that private negotiation trading improves the bargaining position of buyers relative to sellers of ag commodities in spot markets (WY).
In Oct of 2002, The ERS released a new series of retail prices. ERSs data base contains monthly average retail price data for selected cuts of red meat and poultry, based on electronic supermarket scanner data. The data set contains information on volume sold and the discount affects of featuring. The data set accounts for approximately 20% of U.S. supermarket sales.

Impacts
- The pork-fat-color analysis seems to show that barely and white corn produced whiter pork fat, which is preferred in the Japanese market.
- Research indicates that HDP can reduce aging time of retail beef for enhanced tenderness. The reduced energy requirements for extended refrigeration (aging) alone can result in significant savings and increased profits for the meat industry.
- Research results indicate that the CAST gene affects the textural integrity of fresh pork.
- The duration of time from stunning to evisceration was positively correlated with pork loin-chop shear force levels.
- The USDA has made available new scanner data on retail meat sales to the public in October of 2002.
- The rate of return to retained ownership of weaned steer calves is affected by ranch of origin management practices and health management practices before calves are placed in the feedlot.
