  1. The American Hereford Association (AHA) currently produces expected progeny differences (EPDs) for 17 traits and calculates three profit ($) indexes.

  2. To understand the inheritance of the scurred trait, it is important to understand the genetics involved in how the horned/polled trait is inherited. Five keys to understanding include: Polled is dominant to horned, so those animals that carry one gene for polled (PP) and one for horned (Pp) will be polled.

  3. 11 Οκτ 2023 · Hereford cattle carry dominant polled genetics, originally derived from a mutation. By selectively breeding polled Herefords, the horns can be removed. Breeding polled Hereford bulls to horned cows results in polled offspring, eliminating the need for dehorning.

  4. Possessing a typically large, muscular, red frame, with a white face, crest, dewlap and underline—it is one of the two most common purebred beef breeds in the US. The horned Hereford was developed in Herefordshire, England in the mid 18th century.

  5. Understanding Hereford EPDs The American Hereford Association (AHA) currently produces expected progeny differences (EPDs) for 17 traits and calculates three profit indexes. AHA’s genetic evaluation makes use of a Marker Effects Model that allows the calculation of EPDs by incorporating the pedigree, phenotypic and genomic profile of an animal.

  6. 3 Αυγ 2023 · Hereford cattle are known for their distinct markings, including a white face and red body. They are available in two main varieties: the traditional, horned Hereford and the polled (naturally hornless) Hereford. The latter resulted from a genetic mutation that breeds true, meaning that polled bulls will only produce polled offspring.

  7. Polled Hereford are medium framed cattle with distinctive red body color with the head and front of the neck, the brisket, underside, and switch in white. They have well developed fore-quarters, a deep brisket, broad head and stocky legs.
