A Q&A on DWP$ and WT$ – Dairy Wellness Profit $ / Wellness Trait $

Dairy Wellness Profit $ and Wellness Trait $ indexes

The Dairy Wellness Profit $ and Wellness Trait $ indexes may have you wondering whether you should adjust your genetic plan to include this information. We want to help you decide what’s best for your dairy. So we answer a few questions about DWP$ and WT$ to help you better understand these indexes.

What is Dairy Wellness Profit $ (DWP$)?

Dairy Wellness Profit $ (DWP$) is a genetic selection index. It equates to a genetic plan of 34% production–56% health–10% conformation. This differs from TPI (46-28-26) and the overall NM$ index (43-41-16).

The breakdown of the weight on health is different as well. DWP$ puts 30% of the health trait weight on WT$. This leaves 26% for the CDCB evaluated health traits of PL, DPR, SCS, DSB, DCE, CCR, HCR.

What is Wellness Trait $ (WT$?)

WT$ is a combination of the Wellness Traits (ketosis, displaced abomasum, retained placenta, metritis, mastitis and lameness). This means it is an index analogous to a 0-100-0 index, with 100% weight on health traits. However, those weights are divided between the various Wellness traits that Zoetis calculates.

Do each of the Wellness Traits get their own evaluation?

Yes. They are then combined into a Wellness Trait $ index to combine the expected impact.

Does Alta test all bulls for DWP$ and WT$?

No, but we test the sires that we predict will do well on the respective indexes. We test our bulls that have favorable health trait values and rank well on a 34% Production-56% Health-10% Conformation index. We list the top ten DWP$ sires and top five WT$ bulls in each of three categories: G-STARS, FUTURE STARS and daughter-proven sires.

What is Alta’s testing plan going forward?

This will be dependent on the feedback from the customers and the demand for this information. In the short-term we will continue to test those sires that rank well on a traditional 34-56-10 index.

How can we predict which sires will do well on these indexes?

Because the correlation between DWP$ and a traditional 34% production – 56% health – 10% conformation index is very high, we can predict quite well which sires will rank well on the DWP$ index.
