EPD percentiles graph: A graph of an animal’s EPD percentiles is included along with the report, something several breed associations offer. This visual representation shows how the individual’s EPDs compare to the breed average, which is denoted by the line at the 50 per cent mark. (See more below)

EPDs: Inside the numbers

Breaking down a real-life EPD report to understand how to evaluate and apply genetic predictions

Expected Progeny Differences (EPDs) predict the average performance of an animal’s future progeny for a specific trait, compared to other individuals’ progeny within the breed. They predict average group performance, rather than foretelling individual performance.  “If you have a bull with a weaning weight EPD of +50 and another one with a weaning weight EPD […] Read more

Canada’s First Look at Residual Feed Intake EPDs

Canadian Hereford breeders have long believed in the breed’s feed efficiency and now they’re collecting the numbers to back up that claim. Exceptional breeder participation in the Canadian Hereford Association’s (CHA) residual feed intake (RFI) research project has led to Canada’s first-ever expected progeny differences (EPD) for RFI and a related trait called residual intake […] Read more

Five steps to a successful calving season

Preparations in advance makes calving season both easier on you and your herd

Calving season is an exciting time of year in most operations. It is exciting to see new calves hitting the ground, but it can also be exciting in more of a pending emergency sort of way. Most herds that have successful, low-drama calving seasons have several things in common, regardless of their calving season, most […] Read more

Revising the bull pen

Each year, the Dickinson Research Extension Center reviews the bulls from the previous year to cut back on what bulls need to be overwintered. Because the bulls are bought based on their ability to transmit the right genes into the cow herd, their expected progeny difference (EPD) values already have stood the evaluation tests of when they were purchased.
