UNDERSTANDING EBVS

An animal’s breeding value is its genetic merit, half of which will be
passed on to its progeny. While we will never know the exact breeding
value, for performance traits it is possible to make good estimates.
These estimates are called Estimated Breeding Values (EBVs).
In the calculation of EBVs, the performance of individual animals
within a contemporary group is directly compared to the average of
other animals in that group. A contemporary group consists of animals
of the same sex and age class within a herd, run under the same
management conditions and treated equally. Indirect comparisons
are made between animals reared in different contemporary groups,
through the use of pedigree links between the groups.
EBVs are expressed in the units of measurement for each particular
trait. They are shown as + ive or - ive differences between an individual
animal’s genetics difference and the genetic base to which the animal
is compared. For example, a bull with an EBV of +50 kg for 600-Day
Weight is estimated to have genetic merit 50 kg above the breed base
of 0 kg. Since the breed base is set to an historical benchmark, the
