Abstract

About 30 years ago there was concern in both the beef and dairy industries that too much emphasis was being given to accuracy of genetic evaluation. This article will discuss attempts to reduce emphasis on accuracy and, thus increase emphasis on the predictor of genetic value itself which is commonly known as estimated breeding value (EBV). Accuracy is a key component of more useful measures of risk such as standard error of prediction which can be used to create confidence ranges in units of measurement for true breeding value based on the EBV and the standard error of prediction. The concept of standard error of prediction can be extended to comparison of pairs of EBV. The influence of genomic relationships and Bayesian analyses on accuracies and standard errors of prediction will also be briefly introduced.
