Interpretive Summary:

Technical Abstract: Tremendous advancement has been made toward the use of genomics in National Cattle Evaluation of beef cattle during the last several years. While the use of genomics to augment EPD has be positive, there still are very few genetic predictions for novel traits (e.g., feed efficiency, fertility, longevity, survival, disease resistance) that are not part of the regular cattle evaluation system. In order to improve genetic predictions for novel traits, protocols must be developed to increase the collection of phenotypes for these traits. The most efficient sources of phenotypic data include research herds like USMARC and commercial collaborators in the cow/calf, feedlot, and abattoir sectors. This presentation focused on strategies to obtain novel trait phenotypes from these sources and methods to optimize their use in genetic evaluation using strategies such as targeted functional genotyping and DNA pooling.
