Simmental milk EPDs
« on: February 27, 2020, 10:42:01 AM »
I am new to breeding Simmentals and cant help but notice how many bulls have horrible milk EPDs.

Seems like about every bull I want to use ends up with a milk EPD in the bottom 95% of the breed.

Are the daughters out of bulls with a low milk EPD milking good? Lots of breeders are using these bulls extensively so I cant help but think its not really reliable.

Seems there would have to be some justification for a bull thats been used 4-5 years that has a low milk EPD but I may be wrong.

We had Simmental-influenced cattle since 1984... never had one that didn't have plenty of milk.
You do realize that the Milk epd is not a maternal trait... it's a production trait, and comes with a feed price tag, just like the other production traits... WW & YW.   
Don't know that I ever gave any significant consideration to Milk epd when choosing a SM sire... except trying to find one that wasn't too high!

First thing youve got to do is to stop interpreting EPD levels as inherently good or bad.   You used the word horrible to describe a low value.  Thats not a sound approach.  The EPD unit of measurement itself is nothing but data.  This data only identifies a particular level of performance  Only once its viewed within the context of the RESOURCES available in your production environment can that data THEN be used as useful information.

With a breed like Simmental whose origins are dual purpose-  the milk levels of those in the top percentiles represent dairy production levels and are wayyyy too high for any commercial beef application.  This likely holds true for any milk production levels (EPd) above the 50 percentile mark. 

I dont know Simmental bloodlines but if the breeders you mention are cattleman and theyre using bottom 95th percentile milk EPd bulls, my speculation is that this bottom 95% milk level is still adequate.
