GENOMIC ENHANCED EPDs
Doubet Ranch participated in the American Salers Association Cow Herd Genomic Project. We did our best to gather a tissue sample on every active cow and herd bull in our operation. Those DNA samples, along with every calf crop since, have been sent in for testing through the International Genetic Solutions group to help provide the most predictable EPDs to our commercial producers and ourselves in breeding future seedstock. In addition to genotypes the bulls in this catalog have been tested for parentage, color status, and polled status. This tool is a supplement to our very important production traits such as fertility, calving ease, mothering ability, grazing ability, and trailing ability to name a few. The Estimated Progeny Equivalent chart below give you some indication regarding what Genomic Enhanced EPDs can mean to you when purchasing a bull who has not yet had offspring.
Estimated Progeny Equivalents is the average number of progeny records it would take to see an equivalent change in accuracy from a genomic DNA test. For example, if a non-parent animal is genotyped, the accuracy of his/her EPD is akin to an animal that has already produced 25 offspring with a weaning weight record (see table below). Overtime, these estimates will change as statistical models are improved, the number of phenotypes increases, and the information from genomic data improves.
