E671 Elevation Still Leads at 15.2%: How Holstein USA’s August 2026 Top 15 All Connect

In 1966, a Virginia A.I. stud gambled $2,800 on a calf named Round Oak Rag Apple Elevation. Three years earlier, illness forced Lester Fishler to disperse his Nebraska herd, sending a pregnant cow to California where Pawnee Farm Arlinda Chief was born. Today, these two foundation sires still sit at number one and two on the Holstein USA influence ranking, their genetics woven deeply into the DNA of the top 400 proven sires. Discover the human decisions, the unexpected twists, and the enduring consequences that launched the two bloodlines still commanding the global dairy industry. **Key Moments:** - How Walter McClure and George Miller convinced a reluctant sire committee to pay a record price for a ten-month-old Elevation - The moment Wally Lindskoog spotted a pregnant cow in a catalog photo, leading to the birth of Chief in California - Why Elevation's first crop of bred heifers caused serious doubt before they finally calved and proved his worth - The way these two distinct bloodlines converged and branched out through legendary sons like Valiant, Starbuck, and Chief Mark - What the modern influence ranking reveals about the hidden cost of genetic concentration, including the spread of APAF1 and CVM Every pedigree breeder knows the names Elevation and Chief, but the sheer scale of their living legacy is difficult to comprehend. With 15.2% and 14.9% of the genes in today's top 400 proven TPI bulls tracing back to just these two sires, their story is not a museum piece—it is the bedrock of modern genomic reality. We unpack the era before genomics, when A.I. was transitioning to frozen semen and breeding decisions were made on faith, cow family knowledge, and intense physical evaluation. We map the descendants that carry this legacy forward—from O-Man and Mogul to Supersire and Shottle—proving that understanding today's sire list requires knowing the decisions made on two farms more than six decades ago. By examining the unintended spread of recessive haplotypes alongside unprecedented production gains, this history offers crucial perspective for breeders navigating today's concentrated gene pool.
