ResumenThe influence of supplemental tocopherol level (0, 250 and 500 IU RRR--tocopherol/d/steer) and injectable retinol form (retinyl propionate vs retinyl palmitate) on growth performance, carcass characteristics and plasma tocopherol and retinol concentrations were evaluated in 108 Holstein steers fed a steam flaked corn-based finishing diet during 314-d feeding period. There were no treatment interactions (P>0.10). During the initial 112-d period, dietary supplemental tocopherol tended to increase ADG (linear, P=0.07) and DMI (linear, P=0.06). Overall 314-d ADG, DMI, gain efficiency and carcass characteristics were not affected (P>0.10) by dietary supplemental tocopherol. Overall DMI tended to be greater (3\%, P0.10) for steers injected with retinyl palmitate vs retinyl propionate. It is concluded that vitamin E supplementation above basal requirements may enhance growth performance during the initial 112-d phase. However, the overall effect on growth performance and carcass characteristics was not appreciable. Injectable retinol ester form did not affect overall ADG, gain efficiency, or dietary NE. Based on plasma retinol concentrations, the bioavailability of retinyl palmitate is greater than that of retinyl propionate.es_ES
