Genetic evaluation using single-step genomic BLUP in American Angus
Introduction Genomic selection in beef cattle has currently been performed with multistep methods, which uses deregressed EBV to estimate SNP effects and then direct genomic value (DGV) for selection candidates based on their genotypes (Meuwissen et al., 2001; Garrick et al., 2009). The main advantage of this approach is that the traditional BLUP evaluation is kept unchanged and genomic selecti...
متن کاملSire Evaluation for Milking Duration
ACKNOWLEDGMENTS This project would not have been possible without the help of several individuals within the dairy industry. My advisor, Dr. Stan Henderson, provided the opportunity to research this project. Dr. Henderson guided me throughout the project and assisted in obtaining these data. Dr. Henderson also assisted in compiling these data and developing the manuscript. Without the help of D...
متن کاملSire Evaluation for Economic Merit
Procedures for selecting sires are compared in terms of making maximum genetic progress in economic lnerit. A quadratic index, a simplified form of the quadratic index and a linear index to evaluate economic merit, and a restricted index to improve milk as much as possible while holding milk fat percentage constant, all result in nearly equal expected genetic progress in economic merit. Selecti...
متن کاملRunning head : Single - step genomic BLUP for Angus Genetic evaluation using single - step genomic BLUP in American Angus
Predictive ability of genomic EBV when using single-step genomic BLUP 1 (ssGBLUP) in Angus cattle was investigated. Over 6 million records were available on birth 2 weight (BW) and weaning weight (WW), almost 3.4 million on post-weaning gain (PWG), and 3 over 1.3 million on calving ease (CE). Genomic information was available on at most 51,883 4 animals, which included high and low EBV accuracy...
متن کاملBeef symposium: the evolution of beef cattle genetic evaluation.
During the 100-yr history of the American Society of Animal Science, there have been many tools that have been offered to the beef producers of the world. Advancements in reproductive and nutritional technologies have had major impacts on how cattle are managed. However, the advent of beef performance recording and the subsequent advancements in methodology for genetic evaluations and applicati...
