Timothy N. Holt, DVM Lisa Herrick, Certified PAP Technician
At Redd Ranches, PAP selection has been a cornerstone of our breeding program for decades. As we select sires for use in our A.I. program, we carefully consider each sire’s individual PAP score, PAP EPDs when available, pedigree PAP history, and the proven performance of his progeny. Replacement heifers are only retained in our herd if they record a PAP score of 40 or lower, ensuring continued genetic progress for high-altitude adaptability. Combined with over 111 years of running cattle at high elevations, we believe this multi-generational selection for low PAP cattle provides our customers with genetics that can thrive and perform in demanding high-elevation environments. If you have any questions regarding PAP scores or how we incorporate them into our breeding decisions, we — along with Dr. Tim Holt, DVM — would be happy to visit with you.
