April 19 Webinar by Genetics Experts to Give Cattlemen Guidance on Creating the Best Herd
final webinar in series focuses on bull selection
CO (April 12, 2018) – This year’s edition of the NCBA Cattlemen’s
Genetics Webinar Series comes to a close April 19, with a special
presentation that puts a focus on honing bull selection. The
National Cattlemen’s Beef Association teamed up with six genetics
specialists from across the country to offer this series, which kicked
off Jan. 18. The Genetics Webinar Series was designed for producers who would
benefit from genetics knowledge, from the experienced seedstock breeder
to someone who might be new to the cattle industry and needs to better
understand genetics. It is being coordinated by the NCBA producer
education team. Earlier webinars were “The 4 S’s of Crossbreeding:
Simple, Structured, Successful and Sustainable,” “Show Me the Money!
Are there EPDs for Profit?”, and “Fake News: EPDs Don’t Work.” These
webinars can be accessed at www.NCBA.org
under the Producer Education tab. Titled “Putting the Tools to Use: Buying Your Next Bull,” the April 19
webinar puts the genetic concepts covered in the first three seminars
to work, as attendees will go to a virtual bull sale and select the
best bull from a sale catalog for two distinct production scenarios.
The webinar begins at 7 p.m. CDT. Leading discussion on the topic at the webinar will be Matt Spangler,
Ph.D., associate professor and extension beef genetics specialist at
the University of Nebraska – Lincoln, and Bob Weaber, Ph.D., professor
and beef extension specialist at Kansas State University. Joining in
the discussion will be other members of the eBEEF team, a group of six
genetic specialists from five academic institutions who have invested
time and resources in the advancement of the cattle industry through
genetics. According to Josh White, NCBA executive director of producer education,
the genetics webinar series has been an effective extension of NCBA
educational webinars, which was started several years ago. “Some of the
largest participations in our webinars have been for genetics topics in
the spring,” said White. “This 2018 partnership with the eBEEF team has
been a terrific addition to the education we can provide.” Cattle producers are invited to join the webinar live, although
“homework” for the seminar – available at www.NCBA.org
– is advised. The homework includes the eBEEF bull sale catalog and the
eBEEF bull selection scenario. For

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.
George Perry South Dakota State University NAAB Symposium
Assume that a cow breeds 30 cows per year for 4 years. Regardless of the year, bull price per calf sired was higher than the cost of semen.
We could have different bulls for different groups of cows. Bulls for heifers, bulls for maternal calves, and bulls for terminal calves. Consider breeding a calving ease bull to mature cows- you are giving up additional growth with that mating.
Sexed semen causes the differences in sexes of the calves that we would expect to see. The number of bulls and heifers in a calf crop can be skewed even if we do one round of artificial insemination followed by natural service.
Perry's groups used 6 herds with 878 cows breed to 5 different bulls. They used conventional semen and sexed semen from each bull. Gender skewed semen had a pregnancy rate of 52.4% and conventional semen had a pregnancy rate of 67%. When cows have displayed estrus (been in heat) at time of AI, pregnancy rate was 69%. Cows th…
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 cattle production pr…
