Pedigree diversity is your best defense to rising inbreeding rates

Aug 24, 2025 | Educational Blog

In a world where genetic-selection intensity is at an all-time high to meet growing consumer demands with fewer resources, maintaining genetic diversity remains a key focus. At CentralStar, we offer a diverse lineup of sires that deliver industry-leading performance no matter which selection index you use.

Select Sires proudly represents 21.6% (108) of the top-500 Herd Health Profit Dollars® (HHP$®) sires currently active across both young and proven lines. With only nine A.I. companies represented by 10 or more sires on this elite list, it’s important to consider the diversity Select Sires offers while maintaining the elite traits your herd requires.

Genetic diversity continues to be important as inbreeding continues to rise from 7.6% Expected Future Inbreeding (EFI) in 2015 to 9.4% EFI in 2020. As herd sizes grow, having a broad selection of diverse sires to spread across your population is vital. Utilizing genomic young sires is the fastest avenue to create genetic progress, but maintaining genetic diversity in this group is critical to risk mitigation and long-term success and sustainability.

Select Sires remains committed to maintaining diversity while meeting your herd’s needs. Of the 99 uniquely-different paternal sires in the top-500 HHP$ list, Select Sires has 33, which is 18 more than any other company. The Select Sires lineup also offers the largest number of unique maternal and paternal sires among the industry leaders in both HHP$ and TPI.

Continuing genetic excellence while preserving diversity is no small task, but the Select Sires lineup is designed to do just that.
