The American Angus Association® has recently updated its research heifer pregnancy genetic evaluation. Angus breeders continue to submit heifer breeding records to allow selection tools for reproductive traits to be developed.

The second research release includes updated sire heifer pregnancy expected progeny differences (HP EPDs). These EPDs are a tool to increase the chance of a sire's daughters becoming pregnant as heifers during a normal breeding season. “Even though reproductive traits are recognized as being lowly heritable, this research allows us to provide a genetic value to commercial producers in an area of high economic importance,” says Sally Northcutt, genetic research director for the Association.

The Spring 2008 heifer pregnancy research report contains HP EPDs and accuracies for 495 sires, with nearly 70 new sires added to the listing. The release of HP EPDs is in the form of a web-based research report found at http://www.angussiresearch. com containing sire EPDs with a minimum 0.30 accuracy. Printed copies are available on request. If you have questions, contact the Performance Programs Department at 816-383-5100.

The American Angus Association with headquarters in Saint Joseph, Mo., provides programs and services for more than 36,000 members nationwide and thousands of commercial producers who use Angus genetics. Go to for more information.
