Working in Extension brings new experiences daily, including recent conversations with cattle producers about interpreting genetic data for bull selection.
Today’s cattle genetics offer vast amounts of information, which can overwhelm producers deciding which traits matter most. With many expected progeny differences (EPDs) available across breeds, the challenge is to avoid data overload while making sound choices.
Traditional bull evaluation still holds value. Good EPDs combined with good visual appraisal typically indicate a useful animal. Conversely, poor visual structure or condition often outweighs strong genetic numbers because a bull must be structurally sound to breed effectively.
Key physical traits include feet and leg structure, scrotal size, and muscle shape. Many buyers also prefer bulls that are not over-conditioned or fat, making visual appraisal essential.
Beyond visual assessment, producers must determine which genetic traits align with their production goals. For example, feeder cattle producers may emphasize growth EPDs, while seedstock producers might prioritize maternal traits. Often, balanced trait selection is ideal to meet multiple herd needs.
Genomic enhanced EPDs (GE-EPDs) add accuracy by incorporating DNA information. Research by Dr. Charles Martinez at the University of Tennessee found that bull buyers often experience information overload reviewing catalogs.
Buyers rely most on visual appraisal and traditional EPDs, using GE-EPDs less frequently. The study also showed the order of information in catalogs affects decision-making, suggesting producers benefit from clear, focused data presentation.
Increasing EPD accuracy through genomic panels can accelerate genetic progress because bulls contribute half the genetics in a calf crop. Making informed bull selection decisions using both visual and genetic data can significantly impact calf crop value and farm profitability in today’s cattle market.
Continued education on interpreting and applying genomic data will help producers harness its full potential for their herds.
