What Role Does Inbreeding Play in Genetic Base Changes?
April 3, 2025
Genetic base changes include both corrections for observed genetic trends in the population and adjustments to account for future inbreeding. After the April 2025 base change, observed changes in Predicted Transmitting Abilities (PTAs) for individual animals may not match the base change values as closely as they have in the past. This is not due to any errors in the evaluation. It reflects Expected Future Inbreeding (EFI) changes in the population that are larger than they’ve been in the past.

Starting December 2017, the CDCB will publish the second Ayrshire haplotype affecting fertility. The publication of this important information for the Ayrshire breed is possible thanks to the research led by AGIL researches and the cooperation with CDN, who confirmed the preliminary results obtained in the US population.
