INFORMATION
AOD: The actual age of the dam when she calved the bull offered for sale.
CE: Calving Ease, U =Unassisted
Advertisement
BW: Actual weight at birth
WW: Weaning weight in lbs. Adjusted to 205 days.
WI: Weaning Index - Weaning weight as a % of average WW of contemporaries.
YW: Yearling weight in lbs. - calculated as adjusted 205 day weight + (ADG on feed x 165 days)
YI: Yearling Index - Weight gain from Weaning to Yearling as a % of average gain of contemporaries. NOTE: All Indexes are calculated within herds, as management may differ somewhat.
EPD s : EXPECTED PROGENY DIFFERENCES
EPDs are a powerful tool that is available for making genetic progress. EPDs incorporate the performance of the individual, along with the performance of all its relatives.
CE: Calving ease - the higher number predicts more calving ease.
BW: Birth. A lower EPD predicts lower birthweights.
WW: Weaning. High weaning EPDs predict higher weaning weights.
YW: Yearling. Higher yearling EPDs indicate greater expected yearling weights.
MILK: Milk EPD should be used to predict the milking ability of the daughters of the bulls in question. Higher milk EPDs project more milk.
REA: Rib Eye Area in sq. in. Describes difference in rib eye size.
MARB: Marbling. Describes marbling potential of calves expressed as difference in grade score.
FAT: Fat thickness in inches. Predicts difference in fat measured at the 12th rib.
CW: Carcass weight in lbs. Predicts differences in hot carcass weight of progeny.
Percentile Tables have been added to take some of the confusion out of the EPDs. A trait listed as 5% would mean that bull is in the top 5% of the breed for that trait. 49% would be slightly higher than breed average, while 51% would be slightly lower than breed average.
TEST INCLUDES PARENT VERIFICATION
