Are We Embracing Science and Technology?

Reprinted with permission of the Missouri Angus Trails

In the summer of 2014 we held a Cattlemen’s Boot Camp at the University of Missouri with support from the Angus Foundation and the American Angus Association. Why did we hold this boot camp? First of all, we take every opportunity to work with good people, and when we were approached by the folks at the Angus Association, we jumped at the opportunity to host the event. But, more importantly we wanted to host this event to encourage cattle producers from across the region to embrace recent and emerging advancements in science and technology.

thompson research center_0443 In the United States it has become popular to distrust or outright dismiss a scientific perspective. We see this trend on the nightly news, in print articles, and on social media. People from all walks of life, from all political parties, and all levels of economic achievement choose not to accept as fact certain topics for which science has reached a consensus. This attitude of rejecting science is not what America was built upon. The founding fathers, men like Thomas Jefferson and Benjamin Franklin, embraced science. Science and technological advancements allowed us to be on the winning side of two world wars. Adoption of technology and research-based best practices has allowed us to be the world leader in agriculture. Now is not the time to turn our back on science and technology.

Technology has been improving at an ever increasing pace. Ninety percent (90%) of the world’s data has been generated in the last two years. Genetic research provides an incredible platform to back this up. In 2000 it cost $10,000 to sequence 1 million base pairs of DNA. Today we can sequence that same amount of DNA for 10 cents! Couple this with improvements in computing and data analyses, and it is clear scientific advancement has never had so many tools to drive improvement.

All considered, however, the adoption of technology in the beef industry has continued to be troublingly slow. The use of artificial insemination and genomic testing in the beef industry continues to lag behind other livestock industries. Specialists in the University of Missouri Extension system continue to provide producers with tools to improve their herds. Beef producers can access information on pasture renovation to decrease fescue toxicosis, forage and hay management to reduce waste, artificial insemination practices to reduce labor and time burdens, and genomic testing to improve their herds. University of Missouri Extension is focused on improving production of Missouri cattle operations. But, producers must be willing to accept and embrace new practices and technologies for this information to impact their profits.

Study your operation for one moment. Are you doing the same things simply out of tradition and ease? Or, are your decisions driven by evidence, profit, and sustainability? When presented with new technology or management practices, do you reject them out of hand, or do you study them and evaluate how or if they may or may not work in your operation? Do you know how your farm is performing, and if so, at what level? Are you recording and tracking data to measure how you are doing? By implementing a data-driven, science-based philosophy new opportunities will be open to your herd. Specialists in the University of Missouri Extension system and the Missouri Angus Association are here to assist you in this process if you come with the desire to embrace science and technology. Are you ready to take the next step?

"Why Do Many Reasonable People Doubt Science?"
Discussing the National Geographic Article

“Science is not a body of facts,” says geophysicist Marcia McNutt ... “Science is a method for deciding whether what we choose to believe has a basis in the laws of nature or not.”
One of the attitudes I try to help beef producers embrace is a scientific, data-driven mindset. This applies to all phases of their operation, from reproduction, nutrition, health, genetics, and other management practices. In the March issue of the Missouri Angus Trails magazine, I encourage producers to take a science-based approach to farming and ranching. If you are a Missouri producer who uses Angus genetics, I encourage you to subscribe to the Missouri Angus Trails. (Also, watch for an article by me in the Missouri Hereford News.)

Joel Achenbach wrote an interesting piece in National Geographic asking "Why Do Many Reasonable People Doubt Science?" With the recent measles outbreak, this topic has been in the news recently. I suggest you make some time to read it. Here are some of my favorite quotes:
The idea that hundreds of scientists from all over the world would collaborate on such a vast hoax is laughable—scientists love to debunk one another. 
I have been on the giving and receiving end of this debunking, and I can attest that scientists love to prove each other wrong! Science truly is self-correcting.

“Science will find the truth,” Collins says. “It may get it wrong the first time and maybe the second time, but ultimately it will find the truth.”

Doubting science also has consequences.

Being right does matter—and the science tribe has a long track record of getting things right in the end. Modern society is built on things it got right.

I strongly believe that a technology-driven attitude is part of what made the United States special. I hope we never abandon that philosophy.

A Big Number for a Little Calf
MU’s dairy program produces a genetically outstanding animal

Written by Randy Mertens

If it wasn’t for genomic testing, Mogul Pastel would be just another heifer calf valued around $750. But her Holstein Association’s USA’s Genetic Total Performance Index (GTPI) is so far beyond average – at 2561 – she’s now recognized as the second highest rated red carrier Holstein calf in the country.

That number, in turn, led to another figure — $25,500 – the price she sold for at the Missouri State Convention Sale in January. She now lives in a New York dairy where she will improve their breeding program.

Pastel is a Holstein heifer born Sept. 9, 2014 at the Foremost Dairy Research Center, one of the research farms of the College of Agriculture, Food and Natural Resources, University of Missouri.

The Foremost Dairy Center is the Division of Animal Sciences’ 820 acre research and teaching farm west of Columbia. The center supports 425 cattle, including Holstein and Guernsey breeds. Its research aims to improve milk production and reproductive efficiency, dairy herd health, nutrition, and milk quality. Foremost plays a key role in the Division’s teaching mission, providing experiential learning opportunities through laboratory courses, undergraduate independent study, the dairy club, and graduate student research projects. The farm is also an essential resource for Mizzou’s College of Veterinary Medicine, supporting clinical training of veterinary students and research in animal health.

Students Help Create Something Unique


About a dozen MU dairy students work at the Foremost Dairy Center each semester, learning the operation of a working dairy farm.

Pastel was part of that learning experience. In fact, as a new management strategy, she was one of the first 20 calves at the farm tested using a genomic DNA panel to increase the reliability of her TPI. It was then her high genetic rating became apparent, said John Denbigh, dairy farm manager.

“We didn’t fully appreciate the significance initially of the high rating,” he said. “When we started getting numerous inquiries about her purchase, it was then we knew she was something unique.”

TPI, or total production index, is a guideline created by Holstein Association to rank Holstein cattle and assist dairy producers worldwide in identifying superior cattle with high production potential, and desirable health and fertility characteristics. TPI also measures an animal’s potential for superior feed efficiency and ability to produce milk. The index also measures the genetic ability to reproduce superior and healthy offspring.

An average Holstein’s TPI is around 1800. Pastel’s $25,500 price will go into the farm’s operating account. The farm’s previous best-selling cow sold for $5,000.

Pastel’s superior lineage came about by the suggestion of a pair of dairy students, Denbigh said. The students had attended a national dairy show and were impressed by the genetic characteristics of a bull named Mountfield Mogul. The students suggested he mate Mogul with a Mizzou heifer named Shameless Patty.

“Mountfield Mogul and Shameless Patsy both have superior genetics,” Denbigh said. “The students’ suggestion to use Mogul as a mating sire turned out to be good advice.” When additional data is not available a calf’s genetic merit is estimated as the average between the sire’s and mother’s ratings. But, with additional data from a genomic test, more precise ratings are achieved, and stars like Pastel can be found. Denbigh continued, “We didn’t expect the result we got. It was one of those things where the moon and stars aligned.”

Pastel’s 2007 Origins


Finding Pastel’s true genetic potential is an example of genomic research going back more than a decade at Mizzou. It was Jerry Taylor, curators’ professor and Wurdack Chair in Animal Genomics, and Robert Schnabel, research associate professor, who helped create the technology used to identify Pastel’s superior potential. In conjunction with USDA researchers, the pair created the Illumina BovineSNP50 BeadChip, an inexpensive and easily used device that investigates variant positions in the DNA of cattle and is used to evaluate genetic merit in both dairy and beef cattle.

Often referred to as a SNP chip, it allows scientists to obtain information concerning the DNA bases present in an animal at over 50,000 predetermined positions within the genome (the genome is the entire DNA of an animal). Since its 2007 introduction, this assay has been applied internationally within the dairy and beef industries to improve genomic selection options, said Jared Decker, assistant professor of beef genetics extension and computational genomics. This approach allows the estimation of an animal's genetic merit at birth from a DNA sample that may be obtained from hair roots, blood sample or even a nose swab.

Predictions of genetic merit made through SNP data are now actively being used by Holstein breeders to make selection decisions on bulls. The industry received immediate benefits from substantial gains in the accuracies of predicted genetic merits early in an animal's life, allowing easier identification of superior animals at a lower cost. This permits more rapid genetic progress, Decker said. The SNP chip is now part of the criteria that identified Pastel’s superior traits.

Research is also continuing today at MU in improving dairy and cattle traits in other ways. The MU animal genomics group is involved in research to utilize DNA technology for the prediction of genetic merit for economically important traits in cattle, including disease susceptibility, feed efficiency, milk production, reproduction, and growth.

Results of the bovine respiratory disease research should conclude in about two years with the testing of a genomic tool to help identify animals with a prevalence to this disease.

“We have so much more information now,” Decker said. “The possibilities for profit are exciting.”

2015 Angus Convention to Host International Genomics Symposium

The American Angus Association® and Angus Genetics Inc. (AGI) will host the first-ever International Genomics Symposium as part of the 2015 Angus Means Business National Convention and Trade Show.

The event takes place Nov. 3 in Overland Park, Kan., and will provide cattle producers with cutting-edge information about advancements in genomics technology – and how these advances impact their businesses.

The symposium is sponsored by GeneSeek, a leading provider of comprehensive genomics solutions to the cattle industry, including the GeneSeek Genomic Profiler (GGP-HD).

“We are excited about the symposium and what it will mean for the cattle business,” says Dan Moser, AGI president. “Genomics is rapidly reshaping the way we produce livestock, and providing producers with the best information available will not only help us improve quality and consistency, but also make our industry more competitive.”

Genomics researcher and entrepreneur Richard Resnick (previously featured on this blog) will be the event’s keynote speaker. Resnick serves as CEO of GenomeQuest, a company that builds software to support genomic medicine, research and individualized treatments. Before becoming a bio-entrepreneur, Resnick was a member of the Human Genome Project at the Massachusetts Institute of Technology. Resnick will be one of several widely acclaimed experts on genomics technology to be speaking at the event.

“GeneSeek has partnered with the Angus breed since 2009, and our sponsorship of the symposium is a natural extension of our long-standing commitment to the breed and the cattle industry,” says Dr. Stewart Bauck, general manager of GeneSeek/Neogen Agrigenomics. “There is intense interest among cattle producers about genomics – and this event will go a long way in serving GeneSeek’s mission not only to advance the use of genomics technology, but also show the positive impacts it will have on producers.”

The rise of genomic testing and evaluation is reshaping the Angus business at an accelerating pace. In fiscal year 2014, genomic testing increased by 32%, and AGI recently reported that genomic testing in the first quarter of fiscal year 2015 grew by more than 56%.

The 2015 Angus Means Business National Convention and Trade Show takes place Nov. 3-5 at the Overland Park Convention Center in Overland Park, Kan. The first-ever convention last year attracted nearly 2,000 progressive producers from across the country. For more information about the convention, visit www.angus.org.


Avoid the Headache: Properly Submitting DNA Samples
Breed Improvement Session
Angus Means Business National Convention

DNA sampling
Tonya Amen, AGI
During the second portion of the Breed Improvement session, Dr. Amen answered the question "How can we avoid sample failure when DNA testing animals?" She gave four points:

  1. Have proper collectors on hand. Blood samples are preferred, as the process can be automated. Blood samples can also be archived, whereas tissue samples cannot be. Contact your DNA service provide or see the Angus website. Have samples properly identified. "You cannot invent your own collection system!" said Amen. A business card, airline barf bag, and other home-remedies won't work!
  2. Practice good sampling technique. Make sure you have a nickel sized spot that has soaked completely through the card. Do not send wet samples-mold will grow like crazy! Make sure samples dry overnight in a safe place (not the dash of your truck!).
  3. Package well. Padded envelopes work well.
  4. Consider shipping method. How long will the sample be in transit?


Staff at AGI have a mantra about blood card sampling—Donor Dams Die. Collect samples on your animals, even if you think you will never DNA test that animal. Better to be safe than sorry.
When sampling twins, hair samples are required due to twins sharing blood in the cows uterus.
If blood cards are stored at home, store in a cool dry place and do not store in plastic.
