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

North American Limousin Foundation Releases Recalibrated GE-EPDs

By Joe Epperly, NALF assistant executive director

Limousin breeders and their commercial customers benefit greatly from new breeding and selection tools. The North American Limousin Foundation (NALF) has launched genomic-enhanced EPDs (GE-EPDs) with the fall 2015 international cattle evaluation. This provides GE-EPDs for all Limousin and Lim-Flex® animals that have completed DNA testing for genomic profiles.

A recalibration in cooperation with GeneSeek® and the Canadian Limousin Association has supplied genomic profiles on more than 4,500 Limousin and Lim-Flex animals. Molecular breeding values from either a high- or low-density genomic profile test are then blended into EPD calculations to produce GE-EPDs. This recalibration has led to the doubling of the number of animals included, the number of traits enhanced, and the genetic correlations.

The advantage to animals with GE-EPDs is increasing EPD accuracy values on many traits equivalent to having 8-20 progeny. This adds greatly to the predictability in selection for genetic merit of young, unproven seedstock. Animals that are genomic-enhanced will have the NALF GE-EPDs displayed on their animal detail screen and performance reports in the NALF-DigitalBeef platform. Traits that are genomic-enhanced are highlighted in yellow on these reports.

"We are excited to offer cutting edge tools for the selection of superior genetics to members and commercial producers purchasing Limousin and Lim-Flex animals. NALF has options for DNA testing that fit both your budget and needs for various traits," says Brittany Barrick, NALF director of registry and performance.

For questions regarding DNA testing options and procedures, contact Brittany Barrack, NALF director of registry and performance at 303-220-1693, ext. 57 or Brittany@NALF.org.
