Dr. Jamie Courter is your Mizzou Beef Genetics Extension Specialist

Image
By Jared E. Decker Many of you have probably noticed that things have been a lot less active on the A Steak in Genomics™   blog, but you probably haven't known why. In January 2021, I was named the Wurdack Chair in Animal Genomics at Mizzou, and I now focus on research, with a little bit of teaching. I no longer have an extension appointment. But, with exciting news, the blog is about to become a lot more active! Jamie Courter began as the new MU Extension state beef genetics specialist in the Division of Animal Sciences on September 1, 2023. I have known Jamie for several years, meeting her at BIF when she was a Masters student. I have been impressed by Jamie in my interactions with her since that time.  Dr. Courter and I have been working closely together the last 6 weeks, and I am excited to work together to serve the beef industry for years to come! Jamie holds a bachelor’s degree in animal science from North Carolina State University and earned a master's degree in animal...

BIF 2016: Genomics, return on investment - fact or fiction?

Tonya Amen
Consultant for Illumina, Inc.

One dairy operation was making $35 per year progress for net merit. After using genomics in late 2009, they were making $50 per year in progress for net merit. After they started testing females, this rate increased to nearly $80.
This dairy herd is now seeing $340 more in life time production by using genomics.

From 2005 to 2008, $B was increasing by $3.77 per year.
From 2009 to 2015, $B increased by $5.62 per year.

From 2013 to 2015, $B increased by $9.31 per year.
A 146% increase in genetic trend.

We have seen more rapid genetic improvement in Angus, Hereford and Simmental, all of which line up nicely with the deployment of GE-EPDs. Thus, it is possible (likely?) that this improved genetic improvement is due to the benefit of genomics.

In the dairy industry, genomics is equivalent to 25 production records, 25 conformation records, and 140 fertility records.
Genomics is saving the Canadian dairy industry $111 million dollars annually.
Genomics is saving the New Zealand Farming Coop $4.2 million annually. The genetic gain is increasing despite the cost saving.

A genomic test for Angus gives a breeder the same amount of information as 17 progeny with records for dry matter intake. A $47 test is much cheaper than doing a feeding trial on 17 progeny.

Three benefits:
1) Identify future problems
2) Identify current problems
3) Gives representative proxies for genetic merit of steer mates

There is also value in avoiding inbreeding. Inbreeding decreases performance, thus avoiding inbreeding helps us to avoid decreased performance. In dairy cattle, there is a $20 lost revenue per year for a 1% increase in inbreeding.

Selecting cattle for placement in a feedlot can be worth up to $38 per head. If we are just trying to use this information for different management, the value is less than $1 per head.

CLARIFIDE plus now can directly predict disease risk in Holstein cattle. As discussed previously, we see large reductions in feed efficiency due to health problems.

Amen's is pointing out that we see a $204 premium for heifers with genomics tests in the Show-Me-Plus program. This leads to a return on investment of 167% to 700%.

Show-Me-Select Board Approves Genomic Testing Requirement for Natural Service Sires

Image
All bulls purchased after February 1st, 2019 for use as natural service sires in the Show-Me-Select Replacement Heifer Program ™  must be DNA tested to have genomic-enhanced EPDs. All bulls used as natural service sires after February 1st, 2020 must have genomic-enhanced EPDs, regardless of when they were purchased. Seedstock producers classifying bulls as Show-Me-Select qualified in sale books must have genomic-enhanced EPDs on those lots. Bulls purchased prior to February 1st, 2019 will be grandfathered into the program, as is the common practice with all natural service sires. However, this grandfather grace period will end February 1st, 2020. At that time for a bull to qualify for use in the program, it must have genomic-enhanced EPDs. Why the change? The Show-Me-Select Replacement Heifer Program has the goal of producing premium heifers that perform predictably as 2 year olds. The program has a history of requiring Show-Me-Select producers to go beyond typical...

New Show-Me-Select Sire EPD Requirements Announced

Image
At the January 4th Show-Me-Select Board of Directors meeting, new service sire EPD requirements were approved. All sires, artificial insemination and natural service, must meet minimum Calving Ease Direct (CED) EPD requirements. In addition to yearly updates, two changes were made. First, no Birth Weight EPD requirement will be published. All commonly used breeds now have CED EPDs available. Second, all breeds in the International Genetic Solutions (IGS) genetic evaluation are now set to a common requirement. In the summer of 2018, breeds within the International Genetic Solutions switched to a single-step BOLT multi-breed genetic evaluation. The EPDs for animals in the IGS genetic evaluation are directly comparable across breeds. In 2017, the Red Angus requirement for CED was a CED of 8, which represents the 30th percentile. Less than 5% percent of heifers breed to a bull with a CED EPD of 8 or larger had calving difficulty. We feel that this require is meeting the need to re...

Bob Hough Comments on Changes at Breed Associations

Bob Hough recently posted the following comment on Facebook (posted with his permission): Early in my career at a breed association, the much beloved American Angus breed executive told me that the secret to success running a breed association was to have a top junior program, keep the books straight, and make sure the numbers (EPDs) don't change. This philosophy meant Angus valued stability in their genetic predictions over keeping them up-to-date with the latest science. The Angus Association also marketed extremely effectively the infallibility of their EPDs because of the size of their database. I will start with the later. Yes, a database needs certain critical mass to make sure the animals are tied, but that can be achieved in a modest size database. After that, data quality far and away outweighs data quantity in assuring the most precise and reliable EPDs possible. On the former point, Angus breeders are simply not use to change. This is not the case in most breed associ...
