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

ARSBC 2018: Tools for Timeliness, Estrus Synchronization Planner & Management Minder

Sandy Johnson
Kansas State University

There are 365 days in a year. There are 283 days of gestation, plus or minus. We have 82 days to get a cow cycling and breed.

Kansas State University and Iowa Beef Center have put together 3 versions of the Estrus Synchronization Planner, Excel, mobile, and multi-group.

The sync planner is freely available at http://www.iowabeefcenter.org/estrussynch.html.

In the tool, you select the type of protocol you are using (estrus detection, estrus detection with clean up AI, and fixed-time AI).


The mobile version is available at www.estrussynch.com.

They also have a multi-group version of the Excel estrus synchronization planner. It is important to enable macros within the Excel program so the sheet can work. This allows you to have two groups of heifers, or a group of heifers and a group of cows. This allows you to print out a calendar.

The estrus planner also produces a supply list.

The estrus planner is focused on the few weeks of breeding. Johnson has created a tool for the other 11 months of a year. This tool is called the Management Minder. This tool helps the routine management not to fall under the radar. Can remind about supply purchases, data collection, management timing.

Show-Me-Select Board Approves Genomic Testing Requirement for Natural Service Sires

Image
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 cat
