AMERICAN ANGUS ASSOCIATION - THE BUSINESS BREED

Functional Longevity

Cow longevity is a major factor in ensuring a herd remains profitable and sustainable. Ensuring females will remain in the herd and produce a calf year after year will contribute to the long-term success of the herd.

The data leveraged for this EPD is production records submitted by members on their females through the Angus Herd Improvement Records (AHIR). The base of this data comes from Inventory Reporting, which is the whole-herd reporting program of the American Angus Association.

Inventory Reporting is designed to ensure every female in the herd is accounted for each year by recording a calf or providing a reason she did not calve. These records collected over the course of the female’s lifetime are essential in to informing the Functional Longevity EPD.
