Genomics

Delivering Genomics Technology to the Beef Industry
Drs. Darrh Bullock, Matt Spangler, Alison Van Eenennaam, and Robert Weaber
This White paper summarizes the application of genomic information for beef cattle as of spring 2013

 

Basics of DNA Markers and Genotyping
Alison Van Eenennaam, Ph. D.
University of California – Davis
This two page article simply explains the fundamentals of DNA and how we use variations in DNA sequence for information about cattle (microsatellites, SNPs, etc.).

The Future Is Here
Wade Shafer, Ph. D.
American Simmental Association
This article explains how ASA uses genomic information in genetic evaluations and how adding this information can improve the accuracy of EPDs.

Marker Assisted EPDs
Matt Spangler, Ph. D.
University of Nebraska-Lincoln
This article summarizes the state of genomically enhanced EPDs for multiple breeds.

Current State Genomic selection Tools for Beef Cattle

Dr. Matt Spangler
UNL Beef Genetics Specialist
University of Nebraska - Lincoln

Genomic technology and its application are rapidly evolving. Dr. Spangler discusses the current application of genomic tools including testing for genetic defects, paternity, genomic enhanced EPDs, and the potential for marker-assisted management. This webinar also focuses on the evolution of marker panels, and how they are being used to date including the numerous breeds that are including this information into their EPDs.

 

Predicting Genetic Merit of Beef Cattle
Dorian Garrick, Ph. D., Rohan Fernando, Ph. D., Kadir Kizilkaya, Ph. D., James Reecy, Ph. D.
Current selection strategies result in annual rates of genetic improvement less than one-quarter of the progress that is theoretically possible if merit could be accurately predicted by breeding age, suggests research—by Dorian Garrick, professor; Rohan Fernando, professor; Kadir Kizilkaya,postdoctoral fellow and James Reecy, associate professor—summarized in this Iowa State University Animal Industry Report.

ASA Experience with Incorporating Genomics into Genetic Evaluation
Lauren R. Hyde, Wade R. Shafer, Stephen C. McGuire, Mahdi Saatchi, and Dorian J. Garrick
At the annual meeting of the American Simmental Association (ASA) in January 2011, the Board of Trustees voted unanimously to fund and initiate the development of genomically enhanced expected progeny differences (GE-EPD). The project required a large number of DNA samples representing heavily used Simmental-influenced bulls.

  • Multi-breed Stayability EPDs: Here’s what you need to know

    Feb 2, 2017 | 14:30 pm

    Multi-breed Stayability EPDs: Here’s what you need to know 1.) Multi-breed stayability: The new stayability EPD is calculated for all cattle in the database (not just for purebred and fullblood Simmental).  As stayability is a very important economically relevant trait for female production, the ability to have stayability calculations[…]

  • ASA releases the first evaluation with BOLT and Single Step genomic enhanced EPDs!

    Dec 28, 2016 | 12:06 pm

    ASA releases the first evaluation with BOLT and Single Step genomic enhanced EPDs! The Spring 2017 EPDs were released on 12/22/16 including a Multi-breed Stayability prediction using BOLT and single step genomic evalution (evaluating the genomics, pedigree, and phenotype information in one process rather than blending in the genomics later).  This marks the[…]
