CE ..... Calving Ease – predicts the ease with which a bull’s calves are born to first-calf heifers or mature cows. Larger number indicates higher percent- age of unassisted births for calves sired by this bull. BW ...... Birth Weight – predicts the difference in average birth weight of a bull’s progeny compared to other bulls. WW ..... Weaning Weight – predicts the difference in average 205-day weight of a bull’s progeny. YW ...... Yearling Weight – predicts the difference in average 365-day weight of a bull’s progeny compared to other bulls. MCE ...... Maternal Calving Ease – The ease with which a sire’s daughters calve as first-calf heifers or mature cows. Larger number indicates higher percentage of unassisted births for calves born out of this sire’s daughters. Milk .... Milk – predicts the milking ability of a bull’s daughter. A positive value indicates above average milking ability. MWW ...... Maternal Weaning Weight – predicts the weaning weight of a bull’s daughter’s calves in pounds. A positive value indicates higher-than- average weaning weights. CW ..... Carcass Weight – predicts the difference in average hot carcass weight. A positive number indicates heavier-than-average carcass weights.
REA .... Ribeye Area – predicts the average difference in ribeye area be- tween the 12th and 13th rib of an animal’s progeny. Express in sq. inches. MARB .. Marbling Score – A subjective evaluation of the amount and distri- bution of intramuscular fat (IMF) measured between the 12th and 13th rib. A positive value indicates higher-than-average marbling. BF or FAT ..... Backfat – predicts the average differences between an ani- mal’s progeny in external fat thickness at the 12th and 13th rib. Express in inches at a given age endpoint. YG ..... Yield Grade – predicts the average differences in cutability and is expressed as a deviation. A negative or lower value is desireable just as a lower Yield Grade is desireable. STAY ..... Stayability – predicts the probability that a sire’s daughters enter- ing the herd will stay in production through 6 years of age. A higher value indicates greater stayability. API ..... All-Purpose Index – Evaluates sires for use on the entire cow herd with a portion of their daughters required to maintain herd size and the remaining progeny put on feed. TI ..... Terminal Index – Evaluates sires for use on mature Angus cows with all offspring put on feed. Maternal traits are not considered in this index.
