Effective progeny counts for interim EPD derived from differing combinations of pedigree, performance and genomic data In addition to the work described above, research projects around the US have been undertaken to identify markers for a variety of traits that are difficult and/or expensive to measure. These include traits like heifer pregnancy, birth weight, feed intake, feed efficiency, disease resistance and the fatty acid profile of beef products. These traits offer significant opportunity to change the cost of production or profitability of beef production systems, yet have been difficult to improve using traditional tools like EPDs. These features make such traits good candidates for genetic improvement via marker assisted selection systems. Watch for inclusion of a number of these novel traits into genetic predictions and selection indexes.
