CLARIFIDE® Plus presents comprehensive ways to combine wellness and other genetic trait predictions into economic-based indexes that measure profitability. The two indexes are Wellness Trait Index™ (WT$™) and Dairy Wellness Profit Index™ (DWP$™).
First, what is a selection index? Selection indexes help producers select for several traits at once, taking into account genetic relationships and economic values. A selection index, such as DWP$, provides comprehensive and specific information on wellness and other performance traits to provide clarity and opportunity to make more profitable animal rankings and decisions.
To learn more about this new offering and set of indexes, let’s zoom in to take a closer look at the two indexes, WT$ and DWP$, to see how they differ and learn the benefits of each.
Focus on wellness, with Wellness Trait Index
The Wellness Trait Index (WT$) focuses exclusively on wellness traits — mastitis, lameness, metritis, retained placenta, displaced abomasum, ketosis and polled — and quickly estimates expected differences in lifetime profitability related to those traits. For example, clinical mastitis is reported to be the most common and overall costly disease condition of dairy cows and, as such, makes up 41% of the relative selection emphasis in the WT$.1
Focus on profit, with Dairy Wellness Profit Index
Dairy Wellness Profit Index (DWP$) describes variation in expected profitability of dairy animals attributed to genetic potential differences for production, fertility, longevity, health and wellness traits. DWP$ differs from other economic indexes because it includes direct predictions for economically important diseases via the addition of wellness traits. By including more characteristics affecting profitability, DWP$ describes more genetic variation in profitability than other indexes.
