Abstract

Two hundred fifty-five purebred Angus bulls had their performance tested by the Wardens Farm in Council Bluffs, Iowa over a 14-year period. The bulls feed intake was recorded individually, and performance and ultrasound measurements were determined. Performance and body composition data were used to estimate required feed intake by Perry and Fox (1997) model, and estimated and observed DMI were compared. Average estimated DMI was 25.84 lbs/day and average observed Dry Matter Intake (DMI) was 24.93 lbs/day. The results indicated that the model is promising in estimating feed intake of purebred Angus bulls, but a few adjustments may be needed in certain situations to increase accuracy in estimating intake of bulls.
