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

Angus University: Focusing on Fertility

Image
 On October 27, 2020, Kelli Retallick and Duc Lu from Angus Genetics Inc. gave a seminar on AGI's research into haplotypes affecting fertility. The dairy industry has been reporting these haplotypes that cause pregnancy's losses for years.  I appreciate that Kelli and Duc emphasized that these should be treated like any other EPD, simply tools that help make selection and mating decisions. No scarlet letters needed! Jerry Taylor reported on USDA funded work on this topic at the 2019 BIF Symposium.  http://blog.steakgenomics.org/2019/06/bif-2019-developing-dna-tests-for.html   Let me know if you have questions about this research or these types of tools!

New research creates DNA tests for heifer fertility

Researchers seek Hereford and Red Angus heifers in include in the trials. By Heather Smith Thomas Reprinted with permission of BEEF Magazine. You can’t sell a calf that’s never born. That’s why fertility is the most important trait in beef cattle because it all has to start with a pregnancy. A heifer that settles early in the breeding season and continues to have a calf on time every year is much better than a heifer that does not breed, breeds late, or has only one calf and then comes up open and must be replaced by another heifer that is expensive to develop. There are a number of methods producers utilize in selecting heifers, but accurate tools to select heifers for fertility and early puberty have not been available—until now. The University of Missouri is doing a research project looking into the genetics of fertility and heifer puberty, led by Jared Decker, state beef genetics Extension specialist. He recently received a grant from USDA-NIFA (National Institute of Food and Agric

A trio of researchers will purchase one GreenFeed Pasture System with the grant Written by Logan Jackson   A trio of researchers in the University of Missouri College of Agriculture, Food and Natural Resources (CAFNR) Division of Animal Sciences recently received a 2020 Research Equipment Grant from C-Lock Inc. to purchase one GreenFeed Pasture System, which measures the amount of methane, carbon dioxide, oxygen, hydrogen and hydrogen sulfide gases released by cattle. GreenFeed Pasture System, C-Lock Inc. Jared Decker, associate professor and state beef Extension specialist, Eric Bailey, assistant professor and state beef Extension specialist, and Derek Brake, assistant professor, are the trio leading the project for CAFNR. Their focus will be on using GreenFeed for the prediction of cow efficiency genetic merit (cow efficiency EPD) by combining gas production data, metabolic theory, and genomic and pedigree data. C-Lock Inc., founded in 2009, developed and patented GreenFeed. This is
