A Steak in Genomics™

I had the privilege of speaking during the North Carolina Cattlemen's Convention. Thanks to Daniel Poole and the North Carolina Cattlemen's staff for bringing me out. Below are my slides. Using DNA on your farm to select more profitable cattle from Jared Decker Midwest producers, if you would like to learn more about these topics (and many more) please attend one of our five  ReproGene Workshops held across Missouri.

Five meetings explain options. Making quality beef for more farm profits becomes predictable by using genetic testing. Meetings across Missouri will review current breeding technology and explain new genomic tools. University of Missouri Extension specialists plan meetings in Maryville, Kingsville, Macon, Springfield and Jackson. The five meetings are called "ReproGene:  Taking the next steps in beef cattle reproduction and genetics." Missouri herd owners can learn to produce more profitable cattle with better genetics.  EPDs, expected progeny differences, guided improvement. With genomic testing, all heifers in a herd can be DNA-tested. This provides accurate predictions of future calf performance. Now producers can use genetic information on the male and female side of the herd, Decker says. On the reproduction side, Dave Patterson will tell of new research that offers better conception rates from artificial insemination (AI). Split-time AI gets more cows pregnant....

Denton, Texas — Cattlemen and women frequently ask if DNA scores are truly predictive of phenotypic results. A recent study completed by the Red Angus Association gathered DNA data on a set of Red Angus calves and followed the cattle through harvest, collecting phenotypic data. The results illustrated the Igenity® DNA scores accurately predicted carcass weight, marbling score and overall carcass value. The cattle were raised and owned by Bob and Elaine Yackley of Onida, South Dakota, and fed at a custom feed yard. A total of 91 head of 2015-born steers comprised the group that was DNA tested with Igenity Silver and followed through harvest to obtain carcass data on each individual animal. The top 25 head with the highest DNA scores for Average Daily Gain (ADG) and marbling were compared to the bottom 25 head, which exhibited the lowest combined DNA scores for the same two traits. Summarized results for the two groups are shown in the table. This comparative analysis reveals that ...

By Elisa Marques Over the last 15 years, I have seen successful launches and some real flops in the path to genomics and biotechnology commercialization. If I were to think about the times we were successful, I would say that in almost all of those cases, we had mastered every single aspect of: Knowing Our Industry’s Players Understanding Our Audience Building a Team of Trusted Advisors The examples mentioned here are specific to the livestock industry, but the strategy itself goes well beyond this industry.

I have published a new fact sheet at eBEEF.org , titled " Hair shedding scores: A tool to select heat tolerant cattle. " Hair shedding scores are an easy and effective way to measure cattle’s ability to cope with heat stress. In this fact sheet, learn the how, when, and why of hair shedding scores. As part of our work in matching a cow's genetics to her environment we have recruited 8,000 cattle to participate in a hair shedding genomic project . Producers collected hair shedding scores on their cattle and are sending us DNA samples for genomic testing. This work was supported by the USDA-NIFA [grant number 2016-68004-24827, Identifying Local Adaptation and Creating Region-Specific Genomic Predictions in Beef Cattle ].

My second piece on genomic prediction was published in the Brangus Journal back in December. The Dance Steps of Genomics Part II: Using Genomics in Your Herd This piece discusses how we get started with genomic testing. What animals should we DNA test and when should we test them? The first article in the series is available here .  What do you think of the article? As always, your feedback is welcome. Loading...

Hat tip to Dr. John Cole, USDA, and Jesse Hoff for bringing this to my attention on Twitter . I need to make an important point: I am not a patent lawyer. I do not have a deep understanding of patent law and nothing in this post should be considered legal advice or council. On November 8, 2016 Canada issued a patent to Ben Hayes and Michael Goddard for genomic prediction. Genomic prediction is estimating an animal's breeding value (i.e. genetic merit) using DNA variants. See the Canadian Intellectual Property Office website for more detailed information about the patent. Meuwissen, Hayes and Goddard first published their work on genomic prediction in 2001. Hayes and Goddard filed for a patent of the method on December 21, 2007 with the United States Patent and Trademark Office. About 23 days later, the Illumina BovineSNP50 Beadchip, a DNA test that can test 54,000 DNA variants quickly and cheaply for cattle, was released at the Plant and Animal Genome Conference. This 50K ...
