In order to allow you to compare these potential young herd sires with the breed average, we have listed their percentile rank along side the
EPDs of several of the most economically important traits. This allows you to make quick reference when selecting for specific traits to fit
your needs.

EPD and Performance Information
The EPDs in this catalog reflect the new base used to calculate EPDs for Limousin cattle. They now have the same look as Angus EPDs. For
commercial producers this rescaling helps simplify the use of Limousin EPDs by managing the set of rankign benchmarks similar of both breeds.
While EPDs of the two breeds cannot be directly compared, if you know the benchmark within the Angus genetic evaluation, you also know the
EPD benchmarks within the Limousin evaluation. Twice a year EPDs are recalculated to include any new data that has been submitted to NALF.
This is don to keep them up to date and improve accuracies. With this in mind, expect EPDs to change on the animals you purchase. The EPDs for
the Lim-Flex caves reflect the combined EPDs of the Angus Association and the current information in the Limousin EPD bank from the sires and
dams of that breed. As this is a fairly new development, the accuracies will be low.
Performance EPDs—
CD EPDs: Stands for Calving Ease Direct and is important when choosing sires to produce calves born easily. The higher the number,
the better.
BW EPDs: Express the difference in birth weight on the progeny of the bulls being compared.
WW EPDs: Express the difference in pounds at 205 days on the progeny of the bull being compared.
YW EPDs: Do the same as WW except it is the weight at 365 days.
MA EPDs: Predict differences in weaning weights from daughter’s calves due to genes inherited for milk.
CM EPDs: Stand for Calving Ease Total Maternal and are important for choosing sires that produce replacement females that give
birth to their first calf easily. The higher the number, the better.
SC EPDs: Are expressed in centimeters of scrotal circumference, and compare the difference expected in sons of the animal. Scrotal
EPDs are a good indicator of age of puberty of both the sons and daughters of the animal.
Carcass EPDs—
CW EPDs: Express the difference in pounds of carcass weight.
REA EPDs: Express the difference in square inches of rib eye area.
YG EPDs: Due to the limited range and usefulness of Limousin in fat thickness EPDs, they have been replaced witht hemore informa-
tive EPDs for yield grade 1. YG EPDs are favored and indicate genetic differences for yield grade and cutability of offspring.
Fat EPDs: Express the difference in the inches of back fat.
MS EPDs: Express the difference in the amount of marbling or flecks of fat in the rib eye.
$MTI Dollar Value Indexes are used to rank animals according to net genetic merit for profit from geentics for post-weanig growth
and carcass performance.
This information should help you analyze and sort the bulls to fit your specific needs. We realize this is a lot of data to use, so please ask us if you
