PLAIN CITY, Ohio, September 25, 2025 – The Roy A. Wallace (RAW) Symposium on Reproduction was recognized with the 2025 Marvin and Arlene Large Pioneer Award during the Applied Reproductive Strategies in Beef Cattle (ARSBC) meeting in North Platte, Nebraska. In 2017, Marvin and Arlene Large of Imperial, Nebraska, were recognized for inventing the Large Breeding Barn and the Marvin and Arlene Large Pioneer Award was established in their honor. The availability of this breeding barn and the ease it brought to timed-A.I. has been attributed to the increased use of fixed-time A.I. in the beef industry.

The RAW Symposium on Reproduction began in 1996 when Select Sires invited a small group of reproductive physiologists to discuss recent progress and the direction of future research efforts regarding practical methods of estrous synchronization of beef cattle. Wallace’s contention to the group was “we can do better,” indicating that current methodologies were not good enough to encourage increased use of A.I. in beef cattle.

In what became an annual meeting, known first as a think tank, this process repeated itself as the group gathered to share new data generated during that year’s breeding season and began to identify emerging research questions. Over time, the group expanded to include a broader network of reproductive physiologists, graduate students and key industry figures.

The think tank meetings were instrumental in the formation and growth of the Beef Reproduction Task Force (BRTF), serving as a foundation for collaborative research, extension efforts and industry-wide progress in the implementation of reproductive technologies.

Roy Wallace played a pivotal role in the discussions and evaluation of data, consistently advocating for practical systems that would enhance the use of artificial insemination among beef producers. His commitment to bridging research with real-world application left a lasting impact on the industry. Following his unexpected passing in 2008, the think tank was renamed the Roy A. Wallace (RAW) Symposium in his honor, recognizing his contributions and legacy in advancing reproductive technologies in beef cattle.

The RAW Symposium continues to be a vital forum for sharing new findings and addressing emerging challenges within the beef industry. The symposium continues to foster collaboration, promote evidence-based practices, and support the ongoing advancement of reproductive technologies.
