History of the development of the Beef Reproduction Task Force (BRTF) and impacts of the BRTF on beef cattle reproductive management

Abstract Text:

The Beef Reproduction Task Force (BRTF) was formed during a period of evolving science that resulted in systems to allow producer-acceptable results with a single fixed-timed insemination.   The group organized and developed goals to enhance productivity and profitability of U.S. beef herds by integrating research and extension efforts with the intent of more effectively transferring the use of reproductive technologies to the field. A key early step was to coordinate efforts in identifying effective breeding management protocols for beef cattle and to clarify their associated acronyms. A short-list of recommended protocols and their acronyms for synchronization of estrus and ovulation in beef cattle was developed based on results from peer-reviewed, published research and a comprehensive review of data collected from the field.  The list of recommended protocols was developed by the BRTF in cooperation with veterinarians and representatives from associated industries.  The synergies of this larger industry-centered working group have resulted in ideas for research and broader educational reach.  Together the group has planned and hosted 17 in-depth meetings at locations in key cow-calf areas across the country since 2002.  These “Applied Reproductive Strategies in Beef Cattle” workshops targeted beef producers, AI industry personnel, veterinarians, allied industry representatives and academicians. A national media sponsor has provided online coverage of the meetings (www.appliedreprostrategies.com) since 2008.  The effectiveness of the team was recognized with the NIFA Partnership Award for Multistate Efforts in 2013.  A 2013 national survey of AI users indicated 97% of respondents (n= 425) were familiar with the BRTF recommended protocol lists. Recommendations from these guidelines were generally used by 65% and sometimes or occasionally used by 20% of respondents.  Resources developed by the group include the Estrus Synchronization Planner in a mobile and spreadsheet version, tools to evaluate cost differences of AI and natural service breeding and numerous publications and support materials on a beefrepro.info website.  The group has set in place a plan to bring in new members to help address changing industry needs.  The multi-state research and extension effort combined with the industry group’s insight and support have provided valuable information in a growing beef AI industry.
