Effect of feeding frequency on feedlot steer performance123

Crossbred yearling steers (n = 270; mean initial BW = 318 kg) were used to determine the effect of feeding frequency on feedlot performance and carcass characteristics. Steers were stratified by BW and randomly assigned to pens. Pens were then randomly assigned to 1 of 3 treatment groups: once-daily feeding (1X), twice-daily feeding (2X), or 3-times-a-day feeding (3X). Steers were fed a standard high-concentrate steam-flaked-corn based finishing ration for 170 d. Steers were housed in pens measuring 6.1 × 18.3 m. Feed was delivered to steers in fence-line (3.7 m in length) concrete bunks (0.31 m per steer). Pen served as the experimental unit, and cattle were slaughtered at a constant days on feed. Average daily gain was similar for steers fed 1X or 2X per day; however, ADG (P < 0.03) and ADFI (P < 0.04) were greater in steers fed 3X when compared with steers fed 1X or 2X. Feed efficiency was similar for all 3 treatment groups. Steers fed 3X had a greater hot carcass weight (P < 0.01) than did steers fed 1X or 2X. No differences were detected between the treatment groups for USDA QG or YG. These data indicate similar performance between feeding 1 or 2 times per day; however, feeding 3 times a day increased ADG, ADFI, and hot carcass weight.
