The American Simmental Association (ASA) is excited to introduce two new annual awards recognizing producers who exemplify the practical application of performance-driven cattle production: the ASA Seedstock Producer of the Year and the ASA Commercial Producer of the Year.

These awards are designed to recognize Simmental breeders and commercial cattle producers who use objective information, genetic selection and sound management decisions to create value within their own operations and throughout the beef industry.

The new awards will complement ASA's existing Golden Book and Lifetime Promoter awards, which will continue to recognize individuals for their longstanding commitment to the betterment of the Simmental breed and the greater beef industry.

The ASA Annual Meeting and Board Meeting is officially scheduled for January 13–15 at the Marriot Hotel Gateway Park, Denver, CO.

We are looking forward to collaborative discussions to shape the year ahead. Stay tuned for details and the official agenda coming soon.
