* Spring 2018 THE Enrollment is now OPEN

Spring 2018 THE inventories are due December 15, 2017. An enrollment Packet was mailed to you if you do not have an email address on your account. You can either complete the paper inventory and mail it to ASA (postmarked by December 15, 2017), or update your inventory online via Herdbook Services. See THE Information for more information.

* Registering an animal of another Breed - Foundation Registration

If you are registering an animal out of a sire of another breed, this sire must be registered in another breed association and then registered with ASA as a foundation animal.

If you are registering an animal out of a cow of another breed that is registered in another breed association the animal will have a more complete pedigree and EPDs if the cow is registered with ASA as a foundation animal.

There is information on registering foundation animals here.

* Oculocutaneous Hypopigmentation (OH)

This is a cosmetic genetic trait affecting Simmental cattle.  For more information on genetic defects click here  

* Within Herd Genetic Trends

You can now see the genetic trends of your herd for 9 EPDs. You can also compare your genetic trend to the genetic trend for all animals in ASAs database. Select the "Trends" option under the "Herd Mgmt" tab above (after logging in). More..

* Check your Performance Advocate Score

"Performance Advocate Scores" are now displayed for THE herds on ASA web site. More..

* Avoid processing delays! Required tests for sires and donor - 

All bulls with semen collected and donor cows must be have a high density DNA SNP analysis. And all sires and donors cows with a carrier in their lineage (CL, DL) or who come from a risk population (PR) for specified genetic defectives must be tested for that defective before registration certificates and EPDs are available on new progeny. Please plan ahead; tests can take from 4 to 8 weeks. No testing is required on dams of natural calves. More..
