Sample Scenarios and Performance Data
Angus Bulls
Scenario
Rank these bulls in the order they should be selected as potential herd sires for
use on a purebred Angus operation in the upper Midwest. This operation prefers
to purchase bulls with indicators of early puberty. The top 20% of the female
progeny will be retained as replacement heifers. Primary income from this
operation comes from the sale of yearling bulls to commercial cattlemen who
retain ownership of their calves and sell market steers on a grid that pays
premiums for yield grade 2 and 3 cattle that grade choice or better. Feed and
labor resources are adequate.

Limousin Heifers
Scenario
Rank these heifers in the order they should be selected as potential
replacements for a purebred operation. Income is derived from the sale of
yearling bulls to commercial producers to be used primarily as terminal sires. A
few elite heifer calves are sold to 4-H and FFA members for exhibition at state
and national shows. This operation retains the top 35% of its heifer calves, so
even though growth and muscle are emphasized, maternal traits are still
important.

Chiangus Heifers
Scenario
Rank these heifers in the order they should be selected as potential
replacements for a two breed (Chiangus x Hereford) rotational crossbreeding
system, located in the west. The top 20% of female progeny will be retained as
replacements. All steer progeny and non-replacement females will be marketed
at weaning as source and age verified cattle. Replacement heifers must be
structurally correct females that excel in volume and fleshing ability. Feed
resources are adequate, but labor at calving is limited.

Suffolk Ewe Lambs
Scenario
Rank these ewes in the order you would select them for a purebred Suffolk
operation in the Western part of the U.S. Primary income is from the sale of
range rams to cross on whitefaced ewes. This operation is known for sheep that
excel in multiple births, performance and muscling.

Corriedale Ewe Lambs
Scenario
Rank these ewe lambs as replacements for a registered Corriedale sheep
operation whose primary income is from the sale of rams and ewes to other
seedstock producers.
The owner of this flock desires to improve the
performance and Scrapie resistance of his sheep, while maintaining their fleece
quality.

*Fleece Spinning Count – defines the wool fiber diameter. The range can be
from less than 36 to greater than 80. An 80 represents a very fine diameter,
whereas a 36 is coarse. All animals in this class fall within acceptable spinning
counts to meet breed standards.
Duroc Breeding Gilts
Scenario
Rank these gilts as you would select them as replacements for a purebred Duroc
operation that sells boars to commercial farrow to finish operations. All hogs not
retained as replacements or sold as boars are marketed on a lean-value basis.
All hogs are housed in confinement.

exhibitors. All progeny not marketed as show pigs will be fed to market weight
and sold on a lean value basis. This swine herd is managed as a total
confinement operation.
