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

 Why are we working on these novel traits?
 Because they have great economic importance.
 Further, they have heritable genetic variation.

 We do have EPDs for feed intake and fertility, but they are not as pervasive as other (weight and carcass) traits.

Continued phenotypic data collection and recording is critically needed. But, the breed associations have to do something with the data. Otherwise, progressive seedstock producers will look outside breed associations for genetic evaluations. This will not be a great outcome for commercial cattle producers.

Nine breeds are already incorporating genomic information into EPD, with many other breeds right on the cusp of releasing genomic-enhanced EPDs.

As genotyping becomes more common and more animals are genotyped, many of the current limitations are eliminated. But, there is continued room for statistical approaches to be refined.

 Genotyping entire cohorts (groups) fixes many of the problems.

Many groups are rapidly expanding the amount of cattle genomic sequence data. But, substantial effort will be required to turn this data into deliverables and information for the beef industry.
