Fertility has long been one of the most economically important traits in dairy production, and the latest Sire Summary introduced a much-needed update to how fertility evaluations are calculated. As dairy cattle genetics have advanced, reproductive performance across the industry has improved significantly over the past two decades. To ensure evaluations continue to provide meaningful insight, the formulas used to calculate fertility traits have been refreshed to better reflect today’s dairy population.
For dairy producers focused on improving reproductive efficiency, Daughter Pregnancy Rate (DPR) remains one of the most valuable indicators to monitor. Higher DPR values generally translate to cows becoming pregnant sooner, reducing days open and supporting improved herd profitability.
Based on the updated fertility evaluation model, several ABS sires have emerged as standout performers for DPR.
Top DPR Stars
29HO22703 WHIPPET-ET
DPR: +2.8
WHIPPET-ET leads this group with an impressive +2.8 DPR. His ranking makes him a strong option for breeders seeking to accelerate fertility improvement while maintaining confidence in modern genetic performance.
29HO22735 REDWOOD-ET
DPR: +2.3
REDWOOD-ET continues to demonstrate balanced genetic value, including excellent fertility potential. His +2.3 DPR positions him among today’s elite fertility sires.
94HO22776 MIDAS-ET
DPR: +2.3
MIDAS-ET matches REDWOOD-ET with a +2.3 DPR, offering producers another high-ranking fertility choice as they build breeding programs focused on reproductive success.
29HO22695 WHIFFLE-ET
DPR: +2.3
WHIFFLE-ET also earns a +2.3 DPR rating, reinforcing his value for operations that prioritize fertility alongside overall herd performance.
29HO22723 HARLAN-ET
DPR: +2.2
Rounding out the list is HARLAN-ET with a +2.2 DPR. His strong fertility profile makes him a sire worth serious consideration for progressive dairy herds.
Why DPR Matters
Fertility impacts nearly every aspect of dairy herd profitability. Cows that become pregnant more efficiently typically spend fewer days open, maintain healthier calving intervals, and help producers maximize lifetime productivity. While no single trait should drive every breeding decision, DPR remains a critical component of a balanced genetic strategy.
The updated fertility formulas help ensure that today’s evaluations accurately reflect modern dairy cattle performance, giving breeders a more effective tool for identifying sires that can contribute to long-term reproductive success.
