cattle, barley, corn, energy, associative effects
Rolled barley was substituted for 0, 25, 50, 75 or 100% of the whole shelled corn in finishing diets fed to steers for 84 days. Increasing barley substitution resulted in a linear (P=.12) decrease in ADG and a quadratic (P<.05) decrease in DM1 with no effect on feed conversion. At the termination of the study, barley substitution caused a linear reduction in carcass weight (P<.01) and dressing percent (P<.01). The 100% substitution of barley for corn reduced (Pc.05) the percentage of carcasses grading choice. Dietary net energy values calculated from steer weights, gain and feed intake increased linearly (P<.10) as barley content of the diets increased, possibly reflecting positive associative effects. Published energy values for barley may not be suitable for least cost pricing in all feeding situations.
