YW EPD - YEARLING WEIGHT Expressed in pounds, predicts growth potential from weaning until yearling between sires. The higher the number the better. MILK EPD - MILK A predictor of a sire’s genetic merit for milk and mothering ability as expressed in his daughters compared to daughters out of other sires. TM EPD - TOTAL MATERNAL A prediction of the total contribution of a sire’s daughter to calf performance. The higher the number the better. SC EPD - SCROTAL CIRCUMFERENCE Expressed in centimeters, a predictor of the difference of scrotal size compared to other sires. The higher the number the better. REA EPD - RIBEYE AREA Expressed in square inches, a predictor of the difference in ribeye area size. The higher the number the better. %IMF EPD - INTRAMUSCULAR FAT Expressed as a percentage, a predictor of the difference for percent intramuscular fat (marbling) in the ribeye muscle. The higher the number the better. ($M) EPD - MATERNAL INDEX Is designed to balance weaning weight with maintenance and fertility. Index includes BW, WW, Milk, YW and SC. The higher the number the better. ($T) EPD - TERMINAL INDEX Is designed for when cows are mated in a terminal system. Index includes YW, REA, IMF and Fat. The higher number the better.
($FE) EPD - FEED EFFICIENCY INDEX Balances post weaning growth with the RFI EPD. Designed to select for animals that excel in feed efficiency and post weaning growth. The higher the number the better. CALVING EASE 5 star (the easiest calving bulls, breed to first time heifers). 4 star (breed to larger frame more developed first time heifers) 3 stars or less (breed to mature cows only) MATERNAL Estimate of maternal efficiency NOT milk. The bulls are scored from 1 to 5 stars. Five star bulls will produce the most profitable and good uddered cows in the industry. Based on calving intervals, udder quality, and mothering ability. EFFICIENCY This refers to post weaning gain, conversion, and residual feed intake. Scored from 1 to 5 stars, where 5 star bulls will produce efficient easy keeping replacement females and top end profitable feeder calves.
CARCASS Balanced combination of ribeye area and intramuscular fat (marbling).
DISP.- DISPOSITION Scored from 1 to 5 stars, with 5 stars being the best. 3 star bulls are best suited for big country. RFI - RESIDUAL FEED INDEX Actual RFI data obtained from our feed efficiency portion of the bull test. RFI is defined as the difference between an animals actual feed intake and its expected feed intake based on size and growth. The lower the number the better. $P - $ PREMIUM An accumulation of average daily gain, feed conversion ratio and residual feed intake. The higher the number the better.
