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

eBEEF.org Monday: Genetic Correlations and Antagonisms

Knowledge of which traits are antagonistic can be utilized to manage the impact of selection decisions on other correlated traits.  However, it is important to remember that although genetic correlations can sometimes create the need to exercise more care in selection to alleviate unintended consequences, these correlations can sometimes be utilized to our benefit.  Understanding the magnitude and direction of genetic correlations can assist in selection decisions.  Utilizing balanced selection for multiple EPDs in a breeding objective or using an appropriate selection index will ensure that genetic antagonisms don’t become a limiting factor for genetic progress.

See the eBEEF.org factsheet for more information.
