Carcass merit project: development of EPDS and genetic marker validation
Carcass and Warner-Bratzler shear force
data on strip loin steaks have been obtained
on over 4,200 cattle from contemporary
progeny groups from the most widely used
sires in 15 beef cattle breed associations (16
breeds). Trained sensory panel evaluations
have been conducted on over 1,500 strip loin
steaks from a sample of contemporary
progeny groups from sires included in the
QTL (quantitative trait loci) validation
component of the project. One breed association
has published Warner-Bratzler shear
force Expected Progeny Differences (EPDs)
for 57 sires of two breeds. DNA analyses
and screening have been completed for 11
QTL on eight sires from several breeds.
EPDs for carcass traits, Warner-Bratzler
shear force, and sensory panel traits may be
completed for several breeds within the year
2001. Information from this project should
allow seedstock producers to improve carcass
traits, tenderness, and other palatability
traits through classical genetic selection or
through DNA marker-assisted selection
