ALL BULLS HAVE BEEN GENOMICALLY TESTED To determine eligibility please refer to the Kentucky Bull Assessment Tool available at http://afs.ca.uky.edu/beef/KBAT-buyers When determining eligibility it’s best to use the bull’s most recent EPDs, those can be found on the American Simmental Association website www.simmental.org
BULL BUYER GUIDE: Definitions of Terms Expected Progeny Differences (EPDs): EPDs are the most accurate and effective tool available for comparing genetic levels. Back Fat (BF): Inches of backfat. Birth Weight (BW): Pounds of birth weight. Calving Ease (CE): Percent of unassisted births when used on heifers. Carcass Weight (CW): Pounds of carcass weight. Maternal Calving Ease (MCE): Percent of unassisted births in first- calving daughters. Milk (MLK): Pounds of weaning weight due to milk. Marbling (MRB): Marbling score. Maternal Weaning Weight (MWW): Pounds of weaning weight due to milk and growth. Ribeye Area (REA): Square inches of ribeye. Warner-Bratzler Shear Force (WBSF): Pounds of force required to shear a steak. Stayability (STAY): Percent of daughters remaining in the cowherd at 6 years of age. Terminal Index (TI): Dollars per cow exposed under a terminal-sire scenario.
Definitions of Terms Continued... Weaning Weight (WW): Pounds of weaning weight. Yearling Weight (YW): Pounds of yearling weight. Yield Grade (YG): Yield grade score.

EXPLANATION OF HOW TO UTILIZE API & TI INDEXES: First, determine which index to use; if you’re keeping replacements use API, if not, TI. Then, just as with EPDs, zero in on the unit difference between bulls. (As described to the left, index units are in dollars per cow exposed.) The difference can be used to determine how much a bull is worth compared to another. Or, put another way, how much you can pay for one bull compared to another. For example, when buying an all-purpose-type sire, you can quickly figure a bull scoring +100 for API is worth an extra $6,000 over a $50 bull if both are exposed to 30 cows over 4 years ($50 diff. x 30 hd. x 4 yr. = $6,000). A percentile- ranking chart is required to determine where a bull’s index value ranks him relative to other bulls in the breed. For more information, visit www.simmental.org.
