Subtle Shifts, Significant Impact: Van Doormaal on the Continuity and Enhanced Precision of the Modernized LPI

Brian Van Doormaal, Chief Services Officer for Lactanet, emphasizes the subtle changes in the modernized LPI and their alignment with producers’ objectives. “It’s not the relative weighting that determines how much of an impact breeding for these traits could have,” Van Doormaal explained during the Open Industry Session webinar. “It’s your expected response when you breed for these traits. And in these cases, the expected response is relatively high.” 

Van Doormaal underscores that the modifications will not compromise producers’ ability to concentrate on specific traits. He asserts, “When all the numbers are crunched, and the newly introduced traits are brought into the index, the list of top-rated bulls in the categories will remain largely unchanged today.” 

He reassures that the anticipated consistency in top performers reflects the robustness of the current system. “What I believe we’ll be looking at next April is an LPI that will be 98 percent correlated with today’s LPI,” he noted. This continuity alleviates concerns among breeders about potential disruptions or strategic shifts. 

Moreover, Van Doormaal points to the high expected response rates from breeding for the newly emphasized traits. This outcome is rooted in rigorous data analysis and the integration of new genetic discoveries, enhancing the predictability and efficiency of the breeding process.
