Expressed in number of calves, is a predictor of the number of calves a sire’s daughters are predicted to produce by 6 years of age compared to that of other sires’ daughters Predicts progeny with lower pulmonary arterial pressure which decreases the risk of contracting high altitude disease (HAD) and right sided congestive heart failure Indicates the favorability of progeny who shed their winter hair coat earlier in the spring (putting less energy into thermoregulation)

Indicates differences in genetic merit for the likelihood of unassisted births in first- calf heifers, expressed as a trait of the heifer. Evaluates differences in genetic merit for the maternal component of calf weaning weight, predominantly due to milking ability of dams (or daughters). Expressed in units of teat size score, indicating a sire will produce daughters with smaller teat size Expressed in units of udder suspension score, indicating a sire will produce daughters with tighter udder suspension Describes genetic differences in age at puberty as indicated by adjusted yearling scrotal circumference. Quantifies genetic differences in the probability of acceptable (calm) versus unacceptable (wild) temperament. Measures differences in breeding value for pounds of carcass weight at a constant age. Communicates genetic differences in fat thickness measured adjacent to the ribeye between the 12th and 13th rib, at a constant age. Describes genetic variation in carcass muscularity as measured by ribeye area between the 12th and 13th rib, at a constant age.
