But, with exciting news, the blog is about to become a lot more active! Jamie Courter began as the new MU Extension state beef genetics specialist in the Division of Animal Sciences on September 1, 2023.

Here is my take—we need to make our decisions on a single metric that takes all available information into consideration. These metrics are expected progeny differences (EPDs) and economic indexes. EPDs combine performance records, information from relatives, information from correlated traits, and—in the case of genomic-enhanced EPDs—results from DNA tests. EPDs are the most accurate measure for a particular trait of the bull's merit as a sire. Economic indexes combine multiple EPDs and economic values of each trait to create a single measure of the bull's merit for increasing a producer's profit. We should not be selectin...
