Red Angus EPDs – Ranch Tested, Building Ranchers' Trust

The abundance of data presented to producers to use in genetic selection decisions has become almost excessive. The majority of bull sale catalogs contain actual and/or adjusted weights and ultrasound measurements, ratios for every trait, and Expected Progeny Differences (EPDs). The Red Angus Association of America (RAAA) has long been an advocate of simplifying selection decisions by placing sole selection emphasis on EPDs. When asked why, the response given is that “the research community has proven that EPDs are superior to actual or adjusted weights in estimating an animal’s genetic merit.” However, no real proof based on Red Angus data is presented to the producer to validate that claim. 

RAAA believes in the science behind our genetic selection tools and can validate their reliability with multiple examples demonstrating the effectiveness of EPDs.
