Using Ultrasonic Backfat, Ribeye and Other Measurements to Predict Carcass Composition of Young Bulls
Recent genetic evaluations have tended to use ultrasound measurements on young seedstock cattle—primarily yearling bulls—rather than carcass measurements from commercial progeny.

Ratio of Calf Weaning Wt. to Cow Wt. is Not an Effective Criterion for Evaluating Efficiency
Even though previous research at South Dakota State Univ. (Dinkel and Brown, 1978) showed that the ratio of a calf’s weaning wt. to its dams wt. as an indicator of cow efficiency had very little advantage over weaning wt. alone in predicting efficiency (TDN consumed by cow and calf divided by calf weaning wt.), there continues to be interest in its use as a measure of efficiency.

Barley Can Replace Hay in Gestating Beef Cow Diets
Previous research has shown that when hay is scarce and/or expensive, corn can be limit-fed to replace a portion of the hay in the diet of pregnant cows as a means of reducing feed costs.

Effects of Early Weaning on Performance and Carcass Traits of Bulls and Steers
Previous research has demonstrated that, compared to steers, intact bulls gain faster and produce carcasses that are leaner, have less marbling, and are less tender. In recent years, a significant segment of consumers has shown a preference for “natural” nonimplanted beef with a minimum of fat.
