Genetic Accounting

By Jackie Atkins, Ph.D., Director of Science and Education at the ASA On a daily basis, cattle operations face management decisions that can make the enterprise either more or less successful. It’s not always easy to know what the right decision is but with some thought and advice from trusted sources, usually the choice becomes…

eBEEF.org – A Great Animal Breeding and Genetics Resource

Have you checked out eBEEF.org yet?  eBEEF is an effort of 6 extension specialist to provide accurate information about breeding and genetics in beef cattle.  The eBEEF team, Drs. Darrh Bullock, Jared Decker, Megan Rolf, Matthew Spangler, Alison Van Eenennaam, and Robert Weaber, gathered material in one spot for an excellent animal breeding resource.  eBEEF has…

Contemporary Grouping

Proper contemporary group design and reporting is vital to evaluating the genetic potential of sires.   You might think reporting all your calves as one contemporary group will make their EPDs more accurate but the reality is you want to assign contemporary groups that reflect how the calves were raised for the best results.  Read the following article,…

American Simmental Association Science Blog

The ASA science blog is your online resource for frequently asked questions about animal breeding at the ASA.  For the past two years we have used a science forum to post brief summaries of topics concerning DNA testing, genetic conditions, and genetic evaluation in beef cattle.  As many of the topics lend themselves better to…

ASA provides genetic evaluation for commercial cattle: Commercial Option in Total Herd Enrollment

Commercial Option is for commercial producers who are interested in having EPDs and economic indexes calculated on their entire herd.  EPDs and indexes are provided on all females and herd sires, while group average EPDs and indexes are provided on steers. This information provides commercial producers with an unparalleled opportunity to make within herd…

Why would animals with good phenotypic measures have mediocre EPDs for the same trait?

keepThe “off-the-cuff” answer is when it comes to animal genetics, what you see is not necessarily what you get. Animals with tremendous individual phenotypes (e.g., heavy weaning weights, stellar reproductive records) can certainly have lackluster genetic value for those traits and vice versa. The reason for this is because an animal’s phenotype is the result…
