Big Country Bulls:

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.

Lot Number

Three Generation Pedigree

Individual Perf. Data Ratio within Contemporary Group / # in Contemporary Group / Adj. Weights & Measurements

EPDs

Expected Progeny Difference (EPDs) is the best estimate of an animals genetic merit for a particular trait. It takes into account the animals own performance compared with its contemporaries and the performance of its relatives compared against their contemporaries.

Calving Ease (CE) Generally represent fewer unassisted births. Higher the number the better.

Birth Weight (BW) EPD Predicts calf size compared to other sires. The lower the number the smaller the calf.

Weaning Weight (WW) EPD Predicts overall growth potential from birth to Weaning. Higher the number the better. Yearling Weight (YW) The EPD predicts overall growth potential. Higher the number the better.

Milk (MK) Predicts the maternal contribution to weaning weight of the calf through milk production and other environmental factors.

Scrotal Size (SC) Actual scrotal circumference records, in centimeters, are adjusted for age of bull 365-days.

Ribeye Area (REA) Ultrasound scanning measurement of rib eye area. The EPD is a prediction of Total Muscle.

Intramuscular Fat (IMF) Measured using ultrasound scan technology. IMF is highly correlated to marbling

Indexes

Terminal Index ($T) is designed to be used when bulls are mated to cows in a strictly terminal system. The EPDs that are used in the calculation of $T are YW, REA, IMF and Fat.

Maternal Index ($M) is designed to balance weaning weight with cow maintenance and fertility. The index includes the EPDs for BW, WW, Milk, YW and SC.

Test Data

BBU Expected Progeny Differences & Indexes: EPD with EPD % Ranking within breed

Feed Efficiency Index ($FE) Balances post weaning growth (the growth from weaning to yearling) with the RFI EPD. This index is designed to select for animals that excel in feed efficiency and post weaning growth.

Test Data

Weight Per Day of Age (WDA) The animals Weight Divided their days of age at that date.

Average Daily Gain (ADG) Average Daily gain over the test.

Current Weight (CURRENT WT) Weight taken prior to catalog being printed. Approximately 40 day before sale.

Fleshing Ability (FLESHING) The natural Ability for the animal to maintain condition in a working environment. Graded from 1-5. 5 being the best.
