This study was conducted to evaluate the effects of supplementing energy daily vs. on alternate days at two levels (1.5× and 2× daily amount) on forage utilization and performance of growing steers grazing stockpiled cool-season perennial grass (CSPG) pasture. Forty-five crossbred yearling steers were stratified by initial body weight (BW) (358 ± 18 kg) and randomly assigned to one of the nine CSPG pasture paddocks (5 steers paddock⁻¹). Each paddock was randomly assigned to one of the three replicated (n = 3) supplementation strategies. A pelleted feed (30.3% neutral detergent fibre; 32.0% starch; 7.2% crude fat) was formulated to provide 3.2 Mcal kg⁻¹ of digestible energy and offered daily (DLY) at 0.6% of BW, or on alternate days at two levels: 0.9% [low alternate (LA)] and 1.2% [high alternate (HA)] of BW. After a 70 d grazing period, forage utilization of DLY (65.2%) was not different (P ≥ 0.69) when compared with LA (63.7%) or HA (65.0%). Also, final BW and cumulative average daily gain of DLY (435 kg and 1.1 kg d⁻¹) were not different (P ≥ 0.11) when compared with those of LA (424 kg and 0.9 kg d⁻¹) or HA (428 kg and 1.0 kg d⁻¹). These results suggest that it is possible to reduce the frequency and amount of energy supplementation in grazing-growing cattle without reducing animal performance.
