If you select genetics based on NM$ (or CM$, FM$, or GM$), it will be important that understand the updates so that you know what you’re selecting for as you create your future herd.
These traits were first released last year, but this is the first proof round where they will actually be included in the NM$ formula.
The new NM$ breaks down a bit differently than in the past. What are the keys to know about the new breakdown?
By choosing to adapt this terminology, we can better discuss your best future herd. A herd made up of efficient, trouble-free 4-Event cows. The term ‘efficiency’ also allows us to most accurately categorize each trait. For example, a trait like RFI (part of Feed Saved) does not have a clear place when we’re limited to the bucket options of production, health, or conformation.
Conformation – With the update, this bucket has very little emphasis and is included at less than 4% weight placed on udders and feet and legs in the NM$, CM$, FM$, and GM$ formulas.
You’ll need a new frame of reference for a bull’s NM$. On average, males and females will increase about 100 NM$. That means bulls that are currently around $850 for NM$ will increase to around $950 NM$. These are the expected increases that the whole industry will see before accounting for any differences from new, August proof info – it’s based solely off the new NM$ formula calculations.
Industry updates create noise – and questions. And that can be distracting.
