Hereford and Red Angus Heifers Recruited for Genomics Research

The University of Missouri is recruiting 2,500 Hereford heifers and 2,500 Red Angus heifers to participate in a heifer puberty and fertility genomic research project. Heifers should be registered Hereford, registered Red Angus, or commercial Hereford or Red Angus. Hereford x Red Angus crossbred heifers targeted for the Premium Red Baldy Program would also be a good fit for the research project. Producers must be willing to work with a trained veterinarian to collect the following data: ReproductiveTract Scores collected at a pre-breeding exam 30 to 45 days prior to the start of the breeding season. PelvicMeasurements (height and width) collected at the same pre-breeding exam 30 to 45 days prior to the start of the breeding season. Pregnancy Determination Using Ultrasound reporting fetal age in days. Ultrasound will need to occur no later than 90 days after the start of the breeding season. In addition, heifers must have known birth dates and have weights recorded eithe

Congratulations to Esdras Tuyishimire who successfully defended his Masters thesis! You can watch a recording of his seminar above.  Discussion of genetic and genomic prediction using these traits is at the 29 minute mark.

  On April 22nd at 10 am Central Time, Esdras Tuyishimire will be presenting his Masters thesis work in a seminar titled, "Genomics of heifer pregnancy, days open, and days to conception in Red Angus heifers". Heifer Pregnancy is a discrete success versus failure observation. Esdras investigated using what day of the breeding season did a heifer conceive (Days to Conception) and how many days of the breeding season was a heifer open (Days Open) as alternative ways to look at heifer fertility.  You can watch a recording of Esdras' seminar:  https://blog.steakgenomics.org/2022/05/video-genomics-of-heifer-pregnancy-days.html   Thanks to the Red Angus Association of America for providing the data for Esdras' research!

BIF 2021: Increase Adaptability Through Use of Hair Shedding EPDs

Decker explains the importance of utilizing hair shedding EPDs to increase animal adaptability. “Hair shedding is linked to milk production, reproduction and possibly animal welfare. Hair shedding is easy to collect and predict so it may play a role in selecting genetics with an improved adaptability to heat stresses,” said Jared Decker, University of Missouri associate professor. He gave his presentation “A Piece of the Adaptability Puzzle: Multi-breed Hair Shedding Genetic Effects and EPD” during the Beef Improvement Federation (BIF) Symposium June 23 in Des Moines, Iowa. Cow efficiency and adaptability is a multi-pronged and complicated puzzle. Researchers have pursued the identification of local adaptation and region-specific genomic predictions in beef cattle using hair shedding scores as an indicator of tolerance to heat stress. Hair shedding scores measure how early the winter hair is shed off in the spring and summer. Cattle tend to shed their winter hair from front to back an

BRTF Webinar: Beef Heifer Puberty and Fertility Genomic Research, What genetic prediction should borrow from reproductive management

 The Beef Reproduction Task Force invited me to present in their 2022 Webinar series. You can watch the webinar below or on Facebook. Thanks again to BRTF for the opportunity to present!
