Please make note that many of the animals were in different contemporary groupings at weaning; therefore, it is not fair to compare birth, weaning and yearling weights from one herd to another.
EPD’S Expected Progeny Difference ( EPDs) is the best estimate of an animal’s genetic merit for a particular trait. It takes into account the animal’s own performance compared with its contemporaries and the performance of it’s relatives compared against their contemporaries. Birth Weight (BW) EPD predicts calf size and calving ease. Weaning Weight (WW) EPD predicts preweaning growth potential. Yearling Weight (YW) EPD predicts overall growth potential. Milk EPD predicts the maternal contribution to weaning weight of the calf through milk production, behavior, immunity and other maternal environmental factors. Scrotal Circumference (SC) EPD predicts not only testicular size of male progeny but also daughters onset of puberty. Ribeye Area (REA) EPD predicts total muscle. Intramuscular Fat (IMF) EPD predicts % of intramuscular fat which is highly correlated to marbling. TERMINAL INDEX (TI) is a bio-economic index which considers six growth and carcass-related traits, each trait weighted according to its heritability and economic importance in a feedlot situation with carcasses valued by weight, yield, and quality grade. The value is expressed in standard deviation terms, which can be difficult to comprehend. IBBA advises breeders to evaluate the percentile rank rather than the actual index value. FERTILITY INDEX (FI) is a bio-economic index which considers six traits, each trait weighted according to its heritability and economic importance in a cow-calf enterprise. The value is expressed in standard deviation terms, which can be difficult to comprehend. IBBA advises breeders to evaluate the percentile rank rather than the actual index value.
HEIFER PREGNANCY (HP) is reported in percentile units and represents the probability of a sire’s daughters becoming pregnant during their first breeding season compared to daughters of other sires. STAYABILITY (ST) is reported in percentile units and represents the probability that a cow will have five consecutive calves compared to her yearling contemporaries. PERFORMANCE Individual performance data is provided as supplementary information as EPDs provide more reliable evaluation of genetics differences of animals. Actual Birth Weight (BW) are reported. Scrotal Circumference (SC) is adjusted to 365 days Brangus EPDs are calculated by the Livestock Genetic Services and are part of a program called the National Cattle Evaluation (NCE). EPD PERCENTILE RANKINGS Individual ranking relative to the entire breed population on a specific trait, represented in the form of a percentage, with 1% being best and 99% being worst.
