2017 North Carolina Cattlemen's Convention

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.

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.

ReproGene Workshops: High-quality, profitable beef made possible by genetic tests

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.
Also coming is the use of sex-sorted semen. This allows making heifers or bulls. The sex can be set before insemination.
Many new tools are available on the genetic side, Decker said. Mostly, the tests are breed-specific. Different tests are used for registered and commercial herds. However, some tests work on crossbred or mixed-breed cattle.
DNA samples can come from blood drawn from a calf’s ear or from the root bulb from tail hair. Many producers use convenient tissue sampling units that take a punch from the ear.
New technology allows breeding higher-value animals, selecting traits that improve pregnancy rates and carry through to final product at the packing plant.
To gain full advantage of the advances will take more attention to marketing of cattle. Further, genetic predictions can actually be used to place a value on the calf crop. Now, the producer can get paid for the genetic merit of their cattle through various programs.
Those attending can start on being a step ahead in building profits in their beef herds. As cattle prices fall, quality premiums gain value. Efficiency improves and adds sustainability.
Options will be explained in the three-hour sessions. A meal will be served at each location.

Red Angus DNA Scores Align with Carcass Results

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 the top-DNA-scoring steers produced heavier carcass weights as a result of faster rates of gain (21-pound advantage). They also had higher average marbling scores and higher quality grades, with notably more upper-two-thirds Choice grade carcasses.

Even in a softened fed-cattle market, the difference in value between the two groups was $50.60 per head favoring the high-DNA-scoring steers. Weight and marbling make a big difference when selling cattle on a grid.

“These cattle had the right combinations of genetics and management in addition to being fed to the correct endpoint,” explained Gary Fike, RAAA director of commercial marketing. “The fact that out of the 50 head in this comparison, there was only one Yield Grade 4 in the low-DNA group and none among the top-DNA steers, is a testament to that.”

Fike, who organized and conducted the field study, further noted that these results demonstrate how DNA can be successfully used in commercial operations. “This is real-world data,” he said. “By using DNA testing and eliminating low-scoring animals for the traits of interest, producers can be confident they are building superior genetic value into their herds. That is why we recommend testing all replacement heifer candidates and culling low-scoring females before breeding."

The Red Angus Association of America serves the beef industry by enhancing and promoting the competitive advantages of Red Angus and Red Angus-influenced cattle. RAAA provides commercial producers with the most objectively described cattle in the industry by seeking and implementing new innovative technologies based on sound scientific principles that measure traits of economic importance.
