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 Markers of Bovine Respiratory Disease Complex (BRDC) Susceptibility

Complex diseases such as BRDC involve the influence of many genes and are by definition hard to predict. Genomic heritability estimates of BRDC susceptibility in Holstein dairy calves is moderately heritable (0.21). The Single Nucleotide Polymorphism assays are finding genomic regions associated with BRDC susceptibility, suggesting that genetic progress in these traits could be made by including the specific SNP markers that are indicators of BRDC disease risk in national cattle genetic evaluations.
