Brief Summary of Minutes of Annual Meeting

The committee met at Montana State University on May 31 and June 1, 2011. There were ten committee members present at the meeting. The W-2177 annual meeting was held in conjunction with regional committee W-1010. Dr. Bret Hess, AES Director at the University of Wyoming and the administrative advisor for W-1010, acted as administrative advisor for the W-2177. Joint committee station reports were provided by members from their respective stations. Project renewal discussions were conducted given that the project expires September 30, 2012. Committee members discussed the long history of collaborative research that has been conducted by past and present members of W-2177. It was decided that a sub group of committee members led by Drs. Tonsor and Oltjen would meet in the fall of 2011 to develop a new five-year proposal for the project.

Outputs include 43 publications. Activities: Bailey (USU) led an analysis of the impact of bovine spongiform encephalopathy (BSE) announcement on the stock prices of agribusiness firms. The impact of the BSE announcement on prices in the chicken, pork, and beef markets was also conducted. Another analysis examined whether or not the U.S. BSE announcement had led to structural changes in the export demand for U.S. beef products in our major trading partners. Belk (CSU) continues to develop new high-resolution imaging technologies to more accurately predict beef eating quality. Calkins (UNL) conducted a restaurant consumer preference study involving source verified Nebraska beef conducted in restaurants located on the east coast and the southwestern part of the United States. Additional work determined if Warner-Bratzler shear force methodology for measurement of meat tenderness could be conducted on the same steaks subjected to slice shear force, determined alternative muscles for traditional Japanese and Korean beef recipes. Fausti (SDSU) led an analysis of the national marketing pattern for slaughter steers and heifers was undertaken to determine the market share and the trend in market share of individual animal pricing marketing channels versus pen level marketing channels. Miller (Texas A&M) examined exit velocity as an indication of animal temperament, eating behavior, live animal performance and efficiency, RFI, carcass characteristics, and tenderness. Temperament class impacted carcass characteristics and tenderness of heifers while RFI classification had minimal effects on carcass and tenderness characteristics. Additional work determined if growth-enhancement technologies affect carcass and tenderness characteristics in feedlot heifers with divergent tenderness genotypes. Nelson and Busboom (WSU) have conducted substantial work with regard to objective four. They have extensively researched fatty acid composition of adipose depots of raw and cooked muscle steaks, examined impacts of diet and aging on palatability of steaks, and determined the threshold level of detection of EPA and DHA in grain-fed ground beef after refrigerated storage. Oltjen (UC-Davis) evaluated producers' costs and benefits associated with participating in animal identification programs. A model of the cow-calf production system was developed showing the interaction of management decisions and use of individual records associated with animal identification. Additional work will show the impact of beef production systems on beef quality. Parcell (U-Missouri) evaluated economics involving the timing of A/I breeding trials in Missouri cow-calf operations. Paterson and Kott (MSU) examined relative feed efficiency of feedlot cattle, beef mineral supplement cyclical behavior, and identifying bull genetic traits that affect feedlot performance. Pendell (CSU) examined the impacts of animal identification and tracing systems adoption on the U.S. meat and livestock industry. Tonsor (KSU) assessed cow-calf preferences for animal identification and traceability. Additional work contributed to animal welfare discussions and associated media impacts on beef demand. Milestones: The overall objectives of this project are to 1) evaluate the cost/benefit of traceability and assess its value in market-based programs; 2) develop science-rooted strategies and technologies to reduce food-borne illness and improve the effectiveness of policies related to food safety and trade; 3) assess supply chain management strategies to identify and overcome barriers that interfere with the transmission of consumer preferences to producers; 4) enhance palatability, processing, and marketing of beef by studying instrument grading, beef flavor and tenderness technologies, and carcass cutting strategies; and 5) determine factors influencing domestic and international consumer preferences for beef. Members have completed substantial gains with regard to objective one. Reports and ongoing work by Oltjen, Pendell, and Tonsor on the costs and benefits of animal identification systems were used by USDA in their decision to stop the NAIS program and in subsequent assessments shaping voluntary identification and traceability systems. Less work this year focused on objectives two and three. Substantial work by Belk, Calkins, Nelson, and Busboom has contributed to objective four. Finally, consumer preferences for beef have been assessed by Calkins and Tonsor in several venues.
