Why DNA?
Why DNA? Source: Food Economics and Consumer Choice (Jeff Simmons, 2008)
Technology defined Practices: Doing it better Products: Using new innovative tools and technologies Genetics: To enhance desired traits in plants and animals Food Economics and Consumer Choice (Jeff Simmons, 2008)
Why DNA? Increased accuracy of selection
Why DNA? Faster rate of genetic improvement
Why DNA? Traits that are difficult and/or expensive to measure and have a large economic impact Carcass traits Feed Efficiency Fertility Immune response Tenderness Longevity Marker-assisted selection has the potential to greatly improve how quickly we can make genetic progress in many traits for which we do and do not currently have EPDs. Dr. Mark Enns, Colorado State University June 2009 Brangus Journal
Why DNA? Parentage Added seedstock value Multi-sire pastures Genetic evaluation for commercial cow-calf producers Solve problems
Why DNA? Manage genetic defects Salvage valuable genetics.
Why DNA? Greater return on assets $
2003 single marker/ single trait limited adoption 2008 Multi-marker tests for a few traits reported in a variety of formats no tie between DNA test results and national genetic evaluation or breed associations GE-EPDs 2012 panels with thousands of markers for many traits results reported in units of the trait incorporation of DNA information into national genetic evaluation 2020 seamless submission of genotype data to national genetic evaluation/breed associations DNA information used for traceability, parentage, genetic defects, selection, marker-assisted management, product differentiation Modified from Van Eenennaam GeneSeek 9/12/2012

Value of Genomic Enhanced EPDs 1. Risk reduction through improved accuracy of selection 2. Value of time 3. Rate of genetic progress
How long will it take to get the same level of EPD accuracy with progeny versus pulling a sample at birth, branding or weaning to get GE-EPDs? $
