Each contemporary group should encompass same sex calves, managed and treated alike,
from the same weaning contemporary group, to be considered a proper contemporary
group for ultrasound. All animals within a contemporary group are to be scanned
on the same day or over no more than three consecutive days. An example would be:
If ten animals from the same weaning contemporary group are scanned on the same
day, they will be in the same contemporary group for ultrasound.
Yearling bulls and heifers that are sent to a central test can be included in national
cattle evaluation procedures for carcass EPDs. To be evaluated, the test animals
must be in a proper ultrasound contemporary group. The above paragraph explains
contemporary grouping. An example of a proper contemporary group would be: Two or
more bulls from the same weaning contemporary group, taken to a central bull test,
will have carcass EPDs generated relative to their weaning group. In contrast,
if just one bull is sent to a bull test, that bull will be evaluated as a contemporary
group of one. If two bulls from separate weaning contemporary groups are sent to
a bull test, those two bulls will be evaluated as separate contemporary groups of
one. It is important to note that the bull's own scan record will not be used to
calculate EPDs if the bull is a single animal in a contemporary group. Thus, if
any parent of this bull has interims, then the bull will have no carcass EPDs.
Many breeders will scan their yearling animals at the same time other yearling traits
are being measured. If the scan weight is to be used as a yearling weight, the breeder
is responsible for submitting the weight as a yearling weight to the Association.
The scan weight will not automatically be used as a yearling weight.
Determine Test Type
Test type describes the management of the animals.
R=Ranch Test (bulls)
C=Central Test (bull test)
The diet code describes how the animals were fed.
- 0% concentrate (no grain, on pasture, some hay)
- Less than (<=) 50% concentrate (Example: whole corn silage, or supplemented with hay)
- Greater than (>) 50% concentrate (Example: full feed, show feed, bull test)
