Fifteen ruminally and 12 esophageally fistulated steers were used in two 28-d trials (late
summer and early winter) to determine the influence of method of supplementation on forage
use and grazing behavior. 1Ceatments were: 1) self-feeding supplement with salt to limit
intake; 2) daily hand-feeding supplement and salt; 3) daily hand-feeding supplement without
salt. Forage intake was not affected by season or supplementation method; however, total diet
organic matter digestibility was higher in the late summer (P<.01) and lower when steers
received supplement without salt (P<.05). Supplementation method did not affect the time that
animals spent grazing or the distance travelled; however, both were greater (P<.01) during the
summer period. Self-feeding supplement did not appear to adversely affect forage use in
grazing beef steers.
