Steer Profitability Competition
Due to increasing interest from adult producers, the Steer Profitability Competition (SPC) is now inviting beef producers of all ages to take part in the IGS SPC program. Commercial, seedstock, and juniors alike from across the industry are invited to experience the opportunities and challenges associated with cattle feeding. The SPC will allow participants to measure and compare the profitability of their animals alongside other calves from a variety of breed types and backgrounds.
New Herdsire DNA Testing Requirement
In January 2025, the American Simmental Association membership voted to approve a resolution requiring a GGP-100K genomic panel on all herd bulls/natural service sires born on or after January 1, 2025.
While it will take time for this rule to impact the membership, it is imperative that seedstock providers begin planning. A genomic test has been required on all AI sires for some time; now, any natural service sire born on or after January 1, 2025, must meet the same DNA requirements (high density genomic panel) as AI sires and donor dams before any of their progeny can be registered. The following guidelines can help members, and those applying for registration, prepare for this change.

W/C Double Down 5014E Pedigree Update
The American Simmental Association has completed a pedigree correction for the bull W/C DOUBLE DOWN 5014E (ASA 3336150) following parent-verification DNA testing on his dam, W/C MISS WERNING 5014C (ASA 3211676), which resulted in a change to her recorded sire. This adjustment has altered W/C DOUBLE DOWN 5014E’s pedigree and breed composition, which in turn affects the breed composition and pedigree of his progeny. All impacted records were automatically updated in the ASA database immediately following his dam’s pedigree change. For questions regarding affected animals, please contact the ASA DNA Department at dna@simmgene.com, or 406-587-4531.
National Classic DNA Results Uploaded
DNA results have been uploaded to Herdbook for all animals that had samples taken during the AJSA National Classic in Madison, WI. To view your animal’s results, visit herdbook.org, log into your account, and search for the animal(s) tested in the “animal search” function. The best way to review results is through the “DNA Detail Report.” If you have any questions, please contact the DNA Department at dna@simmgene.com.
